Recessed Door/Window Alarm Sensors Posts

Sometimes we like to speculate about security system sensors and equipment that, for whatever reason, has yet to be announced for built by manufacturers. Today, we're going to discuss some sensor ideas that we wish existed in reality, but for now only remain ideas inside of our own heads.


Keep in mind that while these ideas may seem very plausible and realistic, they are still nothing more than ideas at this point. None of these ideas have been announced or mentioned by manufacturers, and it's likely that these concepts may never become a reality. This is just for fun, and we're merely floating around ideas. Don't get your hopes up and expect these sensors to be available on our website any time soon. And if you happen to be a manufacturer reading this, then take notes, as we think these products could be big hits.


PowerG Heat Sensor


The PowerG lineup is known for its excellent diversity, as it offers sensors of nearly all types. But one sensor that is noticeably absent from this lineup is a standalone heat sensor. We regularly get requests from Qolsys IQ Panel 2 Plus users who want a fire detection sensor for use in an area where a conventional smoke detector would be prone to false alarms. Such areas can include kitchens, garages, bathrooms, and attics.

We're pretty surprised that Johnson Controls hasn't produced a standalone heat sensor option for their PowerG lineup yet. It could be as simple as making it so that you can disable smoke detection on a dual-function smoke & heat sensor. This is already possible with the Honeywell SiXSMOKE, so we're sure this could be done for the DSC PG9936 as well. On that note, we would also love to see a PowerG equivalent to the Honeywell SiXCOMBO and finally give PowerG System users a truly complete life-safety sensor option with built-in smoke, heat, and carbon monoxide detection.


Honeywell SiX Series Recessed Contact

This is another one we're a little surprised isn't already a thing. While Resideo has been somewhat choosy about which sensor types to make available for the Honeywell SiX Series Lineup, most of the omissions are understandable. But the absence of a recessed door and window contact is a bit of a head-scratcher. Resideo has produced many wireless and wired recessed contacts in the past, so we're not quite sure why they would forget to make an encrypted option for the massively popular Lyric Controller. One theory we have its that they are afraid the wireless signal range would be too lackluster.

While quite not as popular as surface-mount contacts due to the hole-drilling that is required, recessed contacts are appreciated by many users who want an aesthetically pleasing install. It's not like Resideo doesn't already know this. We have seen them offer a wide selection recessed contacts in the past. The company previously went out of their way to make the Honeywell SiXMINICT after the standard Honeywell SiXCT was deemed by many to be too bulky. For now, Lyric users remain stuck using non-encrypted devices like the Honeywell 5818MNL if they want to add recessed door and window contacts to their systems.


Qolsys Dual-Tech Motion Sensor

We've gotten the impression in recent times that Qolsys isn't really making their 319.5 MHz S-Line Sensors a top priority, as they instead seem to be focusing on producing the best security panels possible. The most popular sensors for all versions of the Qolsys IQ Panel 2 Plus are the PowerG Sensors, which are sold under the DSC banner. And it's very telling that the upcoming Qolsys IQ Hub is expected to only support PowerG Sensors and forgo legacy frequencies entirely. But that doesn't mean that Qolsys 319.5 MHz Sensors don't have their merits, and we think that a Qolsys Dual-Tech Motion Sensor would be quite useful.

A dual-tech motion sensor uses both passive infrared (PIR) and microwave detection technology to sense movement. This is opposed to a standard motion sensor that just uses PIR. The advantage to a dual-tech motion is that both its PIR sensor and its microwave sensor must be triggered before the sensor will activate. This can be crucial for false alarm prevention. Dual-tech motions are also known to offer pet immunity, which is often a major selling point for those with dogs and cats. We have seen dual-tech motion sensors made for many different security systems, and users typically have a decent selection to choose from.

But you're a bit out of luck if you need a 319.5 MHz wireless dual-tech motion, as Qolsys never seemed to make one. That's a bit of a letdown, especially considering that the 319.5 MHz version is the most popular model of the IQ Panel 2 Plus. At least the DSC PG9984P remains an option for that system, as well as any other system that can support PowerG.


More Fall Detection Sensors

Nortek Control changed the game for medical alert sensors when they introduced the 2GIG F1-345 Personal Safety Pendant with fall detection technology. Qolsys soon followed suit with their own Qolsys IQ Fall Pendant. Both of these sensors have built-in accelerometers for detecting the rapid change in movement that occurs during a slip and fall accident. They also retained the capability of a traditional medical alert button, as a user can press and hold the button to alert the system during an emergency. We thought that emergency fall sensors would become the next big thing.

But oddly enough, the development of new fall detection sensors seems to have stalled. We have yet to Resideo try their hand at a fall sensor with an accelerometer. The same is true for a potential release for the PowerG lineup from DSC. We're not quite sure what the hold up is, as the offerings from 2GIG and Qolsys have proven to be quite successful. Some members of our team have also proposed the idea of having these sensors send a second alert to the system if a prolonged period of no movement occurs following a detected fall, as such a scenario may indicate that the individual has seriously hurt themselves. There has also been talk of using rechargeable batteries for these devices, in order for the sensor to work for a longer time period before a battery replacement is needed.


Right now, these sensors are just ideas. But the best idea of all is to sign-up for alarm monitoring! Alarm Grid offers monitoring plans for all needs and budgets.

Hi DIYers! Today, we're taking a look at our best wireless recessed door contacts. These devices are great for when you want sensors that are completely hidden and not visible when the door is closed. They take a little bit of extra effort to install, but it's worth it for many users!

Honeywell 5818mnl wireless recessed door sensor and window senso

When you have a recessed contact, you actually need to drill holes into the door and its frame. The hole in the frame is larger and sized to support the main sensor. The hole in the door is smaller and designed to support the magnet. Some recessed contacts use extremely small magnets that can be mounted without drilling holes. There is also the Honeywell 5800RPS, which uses a plunger switch rather than a magnet.

The key with wireless recessed contacts is knowing which ones are compatible with your system. This depends on the wireless receiver that your system has installed. If you have a hardwired panel with no wireless receiver, then you cannot use wireless sensors. It's really no different than any other wireless sensor. You might also want to know the size of the holes you will need to drill. For your convenience, we put together a nifty table that outlines nearly all of the information you could want:

A couple of weeks ago, we released a complete guide to door contact sensors. Today, we're taking a look at alarm window contacts. Admittedly, there's not much difference between door sensors and window sensors. Many can be used interchangeably. But there are a few tips to keep in mind.

Qolsys iq dw mini s encrypted wireless sensors for iq panel 2 qsFirst, let's review how alarm contacts actually work. It is the same general process for both doors and windows. These devices consist of two portions, those being a sensor and a magnet. When the sensor and magnet are in direct contact or very close proximity, a reed switch inside the sensor will remain closed. Once the magnet becomes separated from the sensor, the reed switch will be released, and the sensor will know to alert the system to let it know that the structure has been opened.

The key with window contacts is to place them so that when the window is opened, the magnet and the sensor will become separated. But when the structure is closed, the sensor are magnet will remain in direct or near-direct contact. It is almost always recommended to place the sensor on the stationary frame of the window and the magnet on the moving portion of the window that is opened and closed. This will prevent the more valuable sensor from being pushed around and potentially damaged. The magnet is designed to take much more abuse and use than the sensor itself. Positioning the sensor this way will also make it easier to wire the sensor if a hardwired contact is being used.

Honeywell 951wg wh 3 slash 8 diameter miniature recessed contactOne special note with window contacts is that they are only designed to let a system know when a window has been opened normally. If an intruder smashes a window to gain entry, they will avoid activating a window contact, as long as the sensor remains in contact with its magnet. This means that they might be able to gain entry without setting off an alarm. Fortunately, there are two other types of sensors that can be used to alert an alarm system to a broken window. These are glass break sensors and shock sensors. Glass break sensors detect the audible sound of a window being broken, while shock sensors detect the physical vibrations associated with a broken window. However, these sensors are used for intrusion support only. Unlike a standard window contact, they will not let the user know if the window has merely been left open by accident. But they are still recommended for users who want to know if a window has been broken. We generally prefer glass break sensors over shock sensors, since they tend to work more reliably. It can also be helpful to use monition detection sensors alongside standard window contacts to detect any movement in the building.

Just like door sensors, window sensors can be either surface-mounted or recessed. Another major distinction is whether they are wireless or hardwired. So really, window sensors can be grouped into four major types. These are wireless surface-mounted, wireless recessed, hardwired surface-mounted and hardwired recessed. Choosing the perfect variation for your window and the type of installation you want to perform is crucial for success. Fortunately, it's relatively easy to decide on the perfect type of window sensor for your needs.

Simply put, surface-mounted sensors are installed on the exterior surface of the window and its frame. This means that they will be visible when looking at window. However, these sensors are usually very small and discreet, so they won't normally be drawing direct attention to themselves. A major advantage to surface-mounted sensors is that they are very easy to install, since no holes necessarily need to be drilled. Instead, many surface-mounted sensors and magnets can be mounted using double-sided foam tape.

The other option is to use recessed sensors. These sensors are hidden inside the window and its frame so that they are out of view. To do this, holes must be drilled into both the window and its frame for the magnet and sensor. Using recessed sensors for windows is somewhat less common than it is for doors. This is because some windows don't have an effective solution for drilling a hole to insert a magnet. Additionally, some window manufacturers put disclaimers stating that drilling holes into the window will void its warranty. But if the window has space for a hole to be drilled so that the magnet can be accommodated, then a recessed window sensor can certainly work. Please note that recessed plunger switches aren't normally used with windows, but there's no definitive reason why they couldn't work in certain situations.

A special mention needs to go to the Honeywell 5800Micra. This is a recessed alarm contact specifically designed for use with windows. The advantage to the 5800Micra is that only one hole needs to be made in the window frame for the sensor. The magnet is small enough that it can be surface-mounted on the side or bottom of the window. It uses an adhesive backing to remain securely in place. This is a great way to achieve a recessed installation without having to void the manufacturer's warranty for your window. Please note that the Honeywell 5800Micra is a wireless sensor that operates at 345 MHz. It is part of the Honeywell 5800 Series, and it will only work with compatible systems.

Honeywell 5800micra wireless recessed window contactUsers must also decide between wireless and hardwired sensors for their windows. Wireless sensors are much easier to install, since no wires need to be run. They are the recommended option for almost any DIY installer. Assuming that you have a wireless system with a wireless receiver, there is almost certainly a contact that will work for you. Just make sure that the sensor operates at a frequency that is compatible with your panel. The most common wireless frequencies at 319.5 MHz, 345 MHz, 433 MHz and 915 MHz. Additionally, the encrypted Honeywell SiX Series Contacts, the Honeywell SiXCT and Honeywell SiXMINICT operate at 2.4 GHz WIFI.

If you go with hardwired contacts, the installation will be more challenging, since wires must be run. This can sometimes be an impossible task for the typical DIY user. However, there are two distinct advantages that make hardwired window sensors suitable for certain applications. For one, having them integrate with the building can add to the property value. Users also appreciate the fact that they never need to replace batteries for hardwired sensors.

Below is a table that outlines many of the window contacts available for purchase on the Alarm Grid site. It's actually the same as the one posted for our door contacts guide, only with some minor tweaks for windows. Make special note of the Honeywell 5800Micra at the very bottom!

Door contacts represent some of the most popular sensors that are used with alarm systems. Nearly every setup will incorporate these devices in some form. After all, knowing when a door has been opened is critical for most systems. But there is a lot to consider when choosing door contacts.

Honeywell 5816 wireless door window sensor

A door sensor is a device that is used to let an alarm control panel know when a door has been opened. When this happens, the system will respond depending on panel's current arming state and the programming settings for the zone. Some popular responses for door contacts include requiring a system disarm within the entry delay period, producing a simple chime and triggering an immediate alarm. These responses are present with virtually any door contact and system setup. A previous blog post of ours actually covers the Response Types for door sensors in greater detail. We recommend checking out that post for more information. But while the general functionality is the same across almost any contact, selecting the best option for your system might seem overwhelming.

Perhaps the first thing you should consider is whether you want a hardwired contact or a wireless contact. A wired contact will communicate with the panel through a direct hardwired connection. A wireless contact will communicate with the panel through wireless RF signals. The advantage to a wireless sensor is that it will be much easier to set up, since no wires will need to be run from the system to the sensor. But some users prefer hardwired sensors, as they essentially become a fixture for the building itself. Another advantage to hardwired contacts is that they don't use batteries. This means that a user will never have to buy new batteries for their hardwired contact. There are all types of door sensors in both the hardwired and wireless variety.

If you choose a hardwired contact, you will need to have a hardwired zone available on your system. Most hardwired contacts can be used with nearly any system that supports hardwired sensors. On the other hand, if you choose a wireless contact, you will need to have a wireless zone available. You will also need to make sure the wireless contact communicates at an RF frequency that is compatible with your system. Knowing which wireless RF signals are accepted by your alarm system is very important for getting sensors to work properly. Some of the most popular RF signals used by alarm systems include 319.5 MHz, 345 MHz, 433 MHz, 915 MHz and 2.4 GHz. Remember to always make sure the wireless door contact you choose operates at a frequency that works with your alarm system!

Honeywell pal t wh surface mount door contact and window contact

Another major distinction for door contacts is whether they are surface-mounted or recessed. A surface-mounted contact is visible on the outside of the door. A recessed contact is hidden inside the door and its frame. As a general rule, surface-mounted contacts are easier to install, since no holes need to be drilled. But the advantage to recessed contacts is that the end result can appear neater, since no sensor will be visible. We generally recommend that users installed surface-mounted sensors, due to the fact that they are easier to install and generally offer more reliable performance.

With that in mind, door sensors can be assigned to one of four major categories. These are wireless surface-mounted contacts, wireless recessed contacts, hardwired surface-mounted contacts and hardwired recessed contacts. Regardless of which category a door contact is assigned, these devices generally all work in the same way. Most door contacts consist of a sensor and a magnet. The sensor is installed on the stationary portion of the door frame, while the magnet installed on the moving portion of the door. In most cases, the magnet must be within a half-inch of the sensor. Placing the sensor itself on the stationary portion of the door helps prevent it from being damaged when the door is opened or closed. Once the door is opened, the magnet will separate from the sensor and cause a reed switch inside the sensor to activate. The sensor will then alert the system to let it know that the door has been opened. Please note that there are a few door sensors that are exceptions to this general operation. Namely, recessed sensors that use a plunger switch, like the wireless Honeywell 5800RPS and the hardwired Honeywell 956RPT.

Honeywell 5818mnl wireless recessed door sensor and window sensoBefore we get into general door contacts that would be used for most applications, we want to make special mention of some more unique sensors that would be used for specific setups. Honeywell offers many hardwired wide-gap contacts that can be used with garage doors and industrial applications. The advantage to these sensors is that they can utilize a much larger spacing gap between the sensor and magnet than what is possible with standard door contacts. We have seen some industrial contacts where the spacing gap can be up to 2.5 inches. That's five times the recommended maximum spacing gap for standard door contacts! Some examples of these industrial-grade hardwired contacts include the Honeywell 958, the Honeywell 968XTP, the Honeywell 959, the Honeywell 958-2, the Honeywell 950W, the Honeywell 960 and the Honeywell 7945. Many of these industrial-grade contacts are also suitable for outdoor use. Another option for a garage door is to use a tilt sensor, like the Honeywell 5822T or an Interlogix TX-E401.

But if a user requires a wireless contact for an outdoor application, there only option is really the Honeywell 5816OD. This wireless contact offers a recommended maximum spacing gap of 1.5" inches, and it is great for use with fences and outside doors. It has a nominal range of 200 feet when used with most systems. As a 345 MHz Sensor from the Honeywell 5800 Series, it will work with nearly any Honeywell Alarm System.

Honeywell is known for producing some outstanding security equipment, and their wireless door and window contacts are no exception. With wireless contacts available from both the 5800 Series lineup and the SiX Series lineup, there are certainly some great options. But with all the possibilities, it might seem overwhelming if you are just getting started. This guide will help you choose the perfect wireless Honeywell door and window contact for your needs.

Honeywell 5820l super slim wireless door and window sensorFirst, a user should understand exactly how a door and window contact works. Almost every wireless Honeywell door and window contact functions using the exact same principles. These devices consist of a sensor and magnet. The sensor is the "brains" of the operation, and it is responsible for sending signals to the alarm system. It is typically installed on or inside the door or window frame. The magnet is installed on or inside the door or window itself. The only wireless Honeywell contact that does not use a magnet is the Honeywell 5800RPS. This is a wireless recessed sensor for doors only that operates using a plunger switch.

For proper operation, the device's magnet should be installed very close to the sensor. We usually recommend placing it within a half-inch of the sensor. However, some 5800 Series contacts, like the 5816OD, can function properly with a slightly larger spacing gap. When the door or window is opened, the magnet will separate from the sensor. This will cause a reed switch inside the sensor to activate. When this happens, the sensor will send a signal to the alarm system so that the programmed Response Type can be performed.

It's also important to know the system compatibilities for the different Honeywell wireless contacts. Their wireless contacts come from two different sensor lineups. These are the 5800 Series and the SiX Series. The 5800 Series contacts are unidirectional devices that operate at 345 MHz. This makes them compatible with any Honeywell System or 2GIG System. But the SiX Series contacts are bi-directional, fully encrypted sensors that communicate using 2.4 GHz WIFI. These sensors only work with Honeywell Lyric Systems.

If you have a Honeywell Lyric Controller, then you can choose between any Honeywell wireless contact on the market. But if you have a LYNX Touch or a VISTA System with an added wireless receiver, then you are restricted to the 5800 Series contacts. Additionally, if you are using a 2GIG GC3 or a 2GIG GC2, then you can use either 2GIG Contacts or Honeywell 5800 Series contacts. Any alarm systems that do not accept the 345 MHz frequency are unable to use Honeywell contacts.

The only two contacts in the Honeywell SiX Series Lineup are the Honeywell SiXCT and the Honeywell SiXMINICT. These are both wireless, surface-mount sensors that work exclusively with Honeywell Lyric Systems. What makes these sensors special is that they feature 128-bit AES encryption. Whenever the sensor sends a command to the Lyric System, the system must then send a secure response back to the sensor. The command will only go through if this secure response is received. Many security experts refer to this as a "digital handshake", and it is excellent for preventing any hacking attempts or wireless attacks.

The SiXCT and the SiXMINICT do have a few slight differences. Most notably, the SiXMINICT is smaller and more compact than the SiXCT. The SiXCT measures at 3.13”L x 1.61”W x 1"D, while the SiXMINICT measures at 2.44”L x 1.25”W x .45”D. So users who want a smaller sensors should go with the SiXMINICT. But the benefit of the SiXCT is that it features a larger wireless range (~300 feet) than the SiXMINICT (~200 feet). However, only users with particularly large properties should have to worry about signal range. One thing that these sensors do share in common is that they can both be batch-enrolled with the Lyric Controller.

  • Honeywell SiXCT - The standard SiX Series contact. Features a 300 foot range and encryption. Will only work with Lyric Systems.
  • Honeywell SiXMINICT - The more compact SiX Series contact. Provides a 200 foot range and encryption. For Lyric Systems only.

But the SiX Series contacts aren't for everyone. For one, they will only work with the Lyric Systems. There are also no recessed contacts in the SiX Series lineup. Users who don't have a Lyric Controller or want a recessed sensor should look to the Honeywell 5800 Series instead. This is an incredibly diverse sensor lineup that has an appropriate contact option for virtually any situation. Any Honeywell or 2GIG System will work with these sensors. This includes any Lyric Controller, L7000, L5210, VISTA P-Series, 2GIG GC3, 2GIG GC2 and more. Most 5800 Series contacts feature a 150-200 foot wireless range that can be effectively doubled with the use of a 5800RP Wireless Repeater.

When selecting a 5800 Series Sensor, a user will choose between a surface-mount contact and a recessed contact. With a surface-mount contact, the sensor and the magnet are mounted on the outer surface of the door or window and its frame. But with a recessed contact, the sensor and magnet are installed inside the door or window and its frame. Surface-mount sensors are very easy to install, since they only require screws or double-sided foam tape. But the sensor will be visible on the outside of the door. Recessed sensors are more difficult to install since holes will need to be drilled. However, some users will appreciate the fact that recessed sensors are hidden.

For users who go with a surface-mount sensor there are certainly some great options in the 5800 Series. One of our favorites is the 5800MINI. This is a reliable sensor that boasts an impressive 200 foot range, despite its small size of just 2.2"H x 1"W x 0.25"D. This is arguably the best surface-mount contact in the Honeywell 5800 Series.

  • Honeywell 5800MINI - A small and discreet surface-mount contact. Offers a 200 foot wireless range. Great for almost any application.

But there are other surface-mount options than just the 5800MIIN. The 5816 is the most popular sensor that Honeywell has ever offered. It features a larger size and roughly the same range as the 5800MINI. But unlike the 5800MINI, the 5816 can be used as a wireless transmitter for a normally closed hardwired device. Honeywell also offers the 5820L Slim Line for narrow installations and the 5816OD for outdoor use.

  • Honeywell 5816 - Honeywell's most popular sensor. Can also be used as a wireless transmitter for a single NC hardwired device.
  • Honeywell 5820L - A slim line door and window contact that is great for narrow applications. Features a 150-foot range.
  • Honeywell 5816OD - A surface-mount contact for outdoor installations. Excellent for monitoring fences, sheds and detached garages.

Honeywell also offers some less popular 5800 Series contacts. These include the 5811 (discontinued), the 5814, the 5815 and the 5816MN (discontinued). While these sensors will work just fine, there isn't really any reason to choose them over another 5800 Series contact.

  • Honeywell 5811 - A small and discreet sensor that has since been discontinued. Replaced by the Honeywell 5800MINI.
  • Honeywell 5814 - Another compact sensor option. It is not as robust as the 5800MINI. Its wireless range is only about 100 feet.
  • Honeywell 5815 - An aesthetically pleasing surface-mount contact that has roughly the same functionality as the 5816.
  • Honeywell 5816MN - A discreet surface mount sensor that has been discontinued. Replaced by the Honeywell 5816MN.

There are also several great recessed contacts in the 5800 Series. The Honeywell 5818MNL is a relatively standard recessed contact that can be used with almost any door or window. It features a 200-foot range, and the installation only requires minor drilling. The Honeywell 5800Micra is a recessed contact for windows only. It is a very small sensor with an attached antenna for sending wireless signals. Finally there's the 5800RPS, which uses a plunger switch instead of a sensor and magnet. This sensor can only be used with doors. When the door is closed, the plunger switch will be pressed in. Once the door is opened, the plunger switch will come out and activate the sensor.

  • Honeywell 5818MNL - A standard recessed contact for doors and windows. It is easy to install, and it has a 200 foot range.
  • Honeywell 5800Micra - A small recessed contact for windows only. Its antenna must be adjusted carefully when installing.
  • Honeywell 5800RPS - A recessed sensor that uses a plunger switch instead of a magnet. For use with doors only.

Door alarm sensors, or contacts, are some of the most important devices used with security systems. These devices alert a user whenever their door is opened. They can be used on virtually any type of door. These might include a front door, a back door, screen doors, a patio door, a shed, cabinets and any door inside the building. We typically find that door alarm sensors are some of the easiest to use devices with an alarm system. But still, it can be helpful to read through a comprehensive guide explaining the full ins and outs of these devices. So it here is - everything you've ever to know about door alarm sensors.

Qolsys iq dw mini s encrypted wireless sensors for iq panel 2 qsThe Basics of Door Alarm Sensors

Most traditional door sensors feature a relatively simple design and premise. These devices usually consist of a sensor and a magnet. The sensor is placed on or inside the door frame, and the magnet is placed on or inside the door itself, within a half inch of the sensor. Opening the door will cause the magnet to pull away and separate from the sensor. When this happens, a reed switch inside the sensor will activate. This will cause the sensor to send a signal to the security system, letting it know that the door was opened. The system will then perform the appropriate response based on how the sensor's Response Type was programmed. At the surface, it's all very simple. Some examples of these traditional sensors include the Honeywell 5800MINI, the Honeywell SiXMINICT and the VERSA-2GIG Sensor. Traditional door sensors can be either surface-mounted or recessed.

There's also a second variation of door sensors, known as mechanical door sensors. This type of sensor features a physical switch that is pressed down when the door is closed. When the door is opened, the switch will pop up, causing the sensor to activate. From there, the system will perform the Response Type assigned to the zone for that sensor. This type of door alarm sensor is far less common than the other type of sensor. However, the end result is still the same - the system will still perform the programmed Response Type when the sensor is activated. An example of this type of sensor is the Honeywell 5800RPS. While you are less likely to come across this type of door sensor, it's still worth mentioning just in case. Mechanical door sensors are only available in the recessed variety.

Honeywell 5800rps wireless recessed door and window plunger sensTypes of Door Sensors - The Two Distinctions

Now that you know the very basics of door sensors, you can start thinking about the different types. While almost every door sensors operates using one of the two mechanisms mentioned above, there are two other distinctions that are commonly made between door sensors. These are whether the door sensor is wireless or wired and whether the door sensor is surface-mounted or recessed. These considerations will play a big role in determining which door sensor you choose to purchase for your alarm system.

A wireless door sensor will communicate with an alarm system wirelessly. This will prevent the need for running a wire from the system to the door sensor. This can make wireless door sensors significantly easier to install. Another great aspect of wireless door sensors is that they can usually be auto-enrolled with the security system. That said, a wireless sensor will need to have its battery replaced every three to five years. On the other hand, a wired door sensor will need to be physically connected with the alarm system. This can make the installation considerably more difficult in certain cases. However, a wired sensor will never require any battery replacements.

If you are using a wireless door sensor with a wired alarm system, such as a Honeywell VISTA Panel, then you will need to use a wireless receiver. This will allow the wireless signal to be received by the system. When choosing a wireless door sensor, make sure that the wireless frequencies it uses are compatible with your alarm system. For example, Honeywell Panels look for wireless signals that operate at a frequency of 345 MHz, while Qolsys Panels use signals that operate at a frequency of 319.5 MHz. If you try to use a wireless door sensor that does not communicate at the correct wireless frequency, then it will not function with the alarm system.

Honeywell 5800rp wireless repeaterThe other major distinction between door sensors is surface-mount sensors versus recessed sensors. Simply put, surface-mount sensors are installed on the outside of the door and its frame, while recessed sensors are installed in the inside. Surface-mount sensors require no drilling. In the easiest scenario, it is possible to mount them using a double-sided adhesive (foam tape). They can also be mounted using screws. With their easier installation, this is generally the preferred type of door sensor. Most users do not mind the fact that a small sensor will be visible on the outside of the door.

Honeywell 5820l super slim wireless door and window sensorHowever, for users who do want a more discrete installation, there are recessed door sensors. These sensors and their magnets need to be inserted into holes that are drilled into both the door and the frame. The exact size of the holes will depend on the specific model of the recessed door sensor that is being installed. Once the sensor and magnet have been installed, they will not be visible from the outside. That said, most users opt for surface-mount door sensors due to the easier installation.

Some Notes on Response Types

The primary function of any security sensor is determined by its Response Type. This refers to what action the system will take when the zone is faulted (e.g. the door is opened). Below are the Response Types that are most commonly used with door sensors:

  • Entry / Exit: If the door is opened while the system is armed stay or armed away, then the system will need to be disarmed within its entry delay period. If the system is not disarmed within this time period, then an alarm event will occur. Most alarms will feature two different Entry / Exit settings. This allows two different entry delay periods to be used on the same system for different zones.
  • Perimeter: If the door is opened while the system is armed stay or armed away, then an alarm event will occur immediately.
  • Interior Follower: If the system is set to armed away, an alarm event will immediately occur if the door is opened, assuming that an entry / exit zone is not faulted first. If an entry / exit zone is faulted first, then the system must be disarmed within its entry delay period, otherwise an alarm event will occur.
  • Interior With Delay: If the system is set to armed away and the door is opened, then the system must be disarmed within its entry delay period. If the system is not disarmed within this time period, then an alarm event will occur.
  • Day / Night: If the system is disarmed and the door is opened, a trouble event will occur on the system. If the system is armed away or armed stay and the door is opened, an alarm event will immediately occur on the system.
  • 24 Hour Audible: Opening the door will immediately cause a full system siren and an alarm to be set off, regardless of what state the system is currently in. This Response Type should not be used unless the door should never be opened for any reason.
  • 24 Hour Auxiliary: Same as 24 Hour Audible, but only the panel itself will produce a siren. Any external sirens or noisemakers will not activate. This zone type is ideal for emergency medical cabinets that would only be opened in a serious medical emergency.
  • 24 Hour Silent: Same as 24 Hour Audible, but no siren or sound will be produced.
  • Fire No Verification: Opening the door will immediately cause a fire alarm to be set off, regardless of what state the system is currently in. This is the ideal Response Type for fire doors.

Certain Response Types are only available for certain Device Types. Depending upon the panel you are using, not all of these Response Types will be made available for the Device Type of "Door". A way to work around this is to set the Device Type to "Other". This will allow you to set any possible Response Type for the door sensor.

2gig dw10 wireless slim door slash window contactOther Programming Settings

Programming a door sensor has to do with more than just the Response Type and the Device Type. Below are some of the other programming settings available for a door sensor. Please note that these settings are specific for a Honeywell Lyric Controller, and different settings may be available on another type of panel.

  • Serial Number: This is how the system will specifically identify the exact door sensor that is being used.
  • Loop Number: This tells the door sensor what function it should perform. Each door sensor usually has a specific loop number that should be set for the device to function as a door sensor. Some door sensors have multiple possible functions that can be used with the device. One example is the Honeywell 5816, which can be used as both a door sensor and as a wireless transmitter depending upon the loop number that is set.
  • Zone Descriptors: These serve as the name of the door sensor. The panel will announce the zone descriptors whenever the zone for that sensor is affected.
  • Alarm Report: This tells the system whether or not it should send an outbound signal to the central monitoring station. If you turn this off, then all the sounds and sirens will still be made, but a distress signal will never be sent to the central station. An example for turning this off might be if you are monitoring a liquor cabinet to make sure your teenage doesn't get into it. You might want a very loud siren to go off so that you know if this happens. However, you obviously wouldn't want the police to show up at your house in this situation!
  • Chime: This will have the panel produce a simple chime whenever the door is opened. Many panels will allow you to toggle between different chime options for the panel. Remember, you will still need to have the local chime for the system enabled from the main settings menu.
  • Supervision: This will have the system monitor the door sensor for low battery or loss of signal. Keep this enabled to make sure that the door sensor is always in proper working order. This setting is only used with wireless door sensors.

For any programming questions related to a specific panel, please consult the programming guide for that panel. This information is readily available on the Alarm Grid website in the form of FAQs.

Common Door Sensor Questions

Below are some questions that are commonly asked about door sensors:

1. How do I program my door sensor?

If it is a wireless door sensor, it can most likely be auto-enrolled.This is accomplished by accessing zone programming on the system and then faulting and restoring the door sensor three times to learn it in. You can fault and restore the door sensor by separating the sensor and the magnet and then clicking them back together. From there, make any necessary programming configurations on the panel. See the above information on Response Types and other programming settings.

If it is a wired door sensor with a hardwired VISTA Panel, then we recommend consulting this FAQ. You may also need to consult the VISTA 15P and 20P Programming Guide.

2. How long do door sensor batteries last?

A wireless door sensor will typically require a battery replacement every three to five years. Wired door sensors do not use batteries, and they will never require a battery replacement.

3. How close should the door sensor be to its magnet?

We usually recommend placing the door sensor magnet within a half inch of the sensor. Some sensors may allow for a greater separation distance than others before a faulted zone will occur. The closer the magnet is to the sensor, the less likely an unwanted fault or a false alarm is to occur.

4. Are there any encrypted wireless door sensors?

Yes, there are encrypted wireless door sensors. The Honeywell SiXCT, the Honeywell SiXMINICT, the Qolsys IQ DW MINI-S and the Qolsys IQ Recessed Door-S are all encrypted wireless door sensors.
