We're checking out the best environmental sensors for our top security system picks for the 2020 holiday shopping season, which are the Honeywell Lyric, the Qolsys IQ Panel 2 Plus, and the 2GIG GC3e. Environmental sensors include life-safety sensors, flood sensors, and temperature sensors.


If you haven't seen our alarm panel 2020 holiday buying guide or our security sensor 2020 holiday buying guide, then be sure to go and check those out, as they will give a nice introduction to this buying guide for environmental sensors. You will need to make the same compatibility considerations for environmental sensors as you do for security sensors. The sensors you choose must be compatible with your system and communicate at a wireless frequency that is accepted by the alarm panel you are using.

As a refresher, here are the compatible sensor lineups for our recommended systems. Just like last time, the sensor lineups that are italicized and underlined represent the encrypted sensors that provide extra wireless security and protection.

While security sensors look for signs of forced entry and unauthorized access, environmental sensors look for undesirable environmental conditions. Specifically, we offer environmental sensors that look for life-threatening conditions, such as a fire or the presence of carbon monoxide (CO) gas. We also offer environmental sensors for detecting floods, water leaks, and unusually high or low temperatures that indicate a broken HVAC system. We will cover each type of environmental sensor in greater detail later in this holiday buying guide.

Adding environmental sensors to your system offers a few advantages. For one, it makes your alarm system more versatile so that it is looking for more than just security breaches. You will also be able to check off more boxes on your certificate of alarm (CoA), and that could lead to bigger savings on your home owner's insurance. Make sure to check with your insurance company to see if that is the case.

Life-Safety Sensors

Life-safety sensors monitor for unsafe environmental conditions that could result in a loss of life. Specifically, this group is primarily comprised of smoke and heat detectors and carbon monoxide sensors. There are also special combination sensors and listening modules that we will discuss further down the line.

First, we will take a look at some of our most popular smoke and heat detectors. These sensors monitor for both the smoke and extremely high temperatures associated with a fire. It is recommended that you have at least one (1) of these sensors on each floor of your building, particularly inside of sleeping areas and in central and connecting areas such as living rooms and hallways.

When checking out these sensors, you might also look for one-go-all-go functionality. This means that when one detector on the network activates, all of the other compatible sensors on the network will also activate their sounders. This can be very important for ensuring that everyone is alerted to the emergency. Certain jurisdictions may require one-go-all-go as part of building codes, so check with your local fire marshal to see if that is the case.

Here are our top picks for smoke and heat detectors.

Now let's look at carbon monoxide sensors. These devices respond upon detecting unusually high levels of carbon monoxide (CO) gas. This gas is both odorless and tasteless, making it virtually impossible to detect without a proper sensor. The gas is extremely harmful to humans, and it can result in serious injury or death in a matter of minutes. We recommend installing at least one CO detector on each floor of your home or office. They are often installed outside of garages and furnace rooms where CO events are most likely to occur.

Here are our top picks for carbon monoxide sensors.

Lastly, we want to mention a pair of listening modules. These devices actively listen for the Temporal 3 (T3) sound of an activated smoke detector or the Temporal 4 (T4) sound of an activated carbon monoxide sensor. These are commonly used with wired smoke detectors and CO detectors that would otherwise have no way of interfacing with an alarm system. If your smoke detectors or CO detectors are one-go-all-go, then, a single listening module can take over your entire wired detector network.

Flood Sensors

Next, we'll be looking at flood sensors. These devices use probes to detect water caused by a flood or leak. It only takes a small amount of liquid to activate one of these sensors, so your system will be alerted before any serious damage occurs. Many of these sensors double as temperature sensors, so expect to see quite a bit of cross-over with that section as well. For best results, use your flood sensors in low-plane areas where leaks are likely to occur, such as underneath toilets, water heaters, and in basements. You might also see that some flood sensor have a reporting delay that is used for false alarm prevention. This will be listed in the notes section in the table when applicable.

Let's check out our top picks for flood sensors.

Temperature Sensors

The final type of environmental sensors we'll be checking out are temperature sensors. These sensors look for unusually high or low temperatures that indicate a broken HVAC system. When a temperature sensor is used for high-temperature detection, it should not be confused with a heat detector that looks for extreme temperatures only associated with fires. Instead, the high-end for a temperature sensor will usually activate at around 90°F. When a temperature sensor is used for low-temperature detection, it will sometimes be referred to as a freeze sensor. On the low-end, a freeze sensor will typically activate at a slightly higher than the temperature at which water freezes, which is 32°F. This is done to give the end user a bit of notice so that they can take action before the pipes freeze. You can typically expect a freeze sensor to activate between 40°F and 45°F. Most temperature sensors will offer both high and low temperature detection. And just like in the previous category, there is a lot of crossover with flood sensors, so you may see some repeats from the previous selection.

You have likely heard us talking about the benefits of PowerG Sensors at one point or another. Today, we figured we would break down the benefits of these sensors and explain why we like them so much. Let's take an in-depth look at PowerG Sensors and all of their wonderful benefits.


PowerG Sensors were originally designed for the hardwired DSC PowerSeries NEO Systems. By adding a compatible transceiver unit to your PowerSeries NEO, the system will be able to support PowerG Sensors. Johnson Controls, which you may know as the parent company of DSC, took the technology associated with PowerG Sensors, and brought it over to the Qolsys IQ Panel 2 System. This move was not a major surprise, as Johnson Controls also had partial ownership over Qolsys at the time, and Johnson Controls has since bought out Qolsys entirely.

The addition of PowerG support for the IQ2 marked the beginning of the Qolsys IQ Panel 2 Plus, which is how the system is still marketed and sold today. PowerG support is also available for the DSC Iotega, though that panel has largely flopped due to its lack of local end user programming. Today, the Qolsys IQ Panel 2 Plus represents the most popular panel for supporting PowerG. All versions and variants of the IQ Panel 2 Plus support PowerG Sensors, and their exceptional performance makes them the go-to choice for IQ2+ users who want equipment with the best versatility and protection.

Starting with the range, PowerG Sensors can be used from up to 2,000 feet away from the IQ Panel 2 Plus when they are used in an open air environment. By open air environment, we are talking about a perfect setting with a direct line of sight, and no obstacles between the sensor and the alarm panel. Most homes and businesses do not provide the ideal, "open air" environment, as there are usually walls and metal appliances present. When you see us mention that 2,000 feet open air range, take that with a grain of salt, because in practice, the range is likely a bit less. But still, we can undoubtedly say that PowerG offers arguably the best wireless range in the security industry. Even if its nominal range isn't quite as far as its "open air range", it is still a very powerful signal that can help you overcome the range issues that other sensor lineups may experience. It is great for use in detached garages, barns, multi-building complexes, and even just large industrial buildings.


To make matters even better, there is also a PowerG Repeater, the PG9920. This device will effectively double the range of any PowerG Sensor and help you overcome range limitations caused by thick walls and other obstacles or signal disruptions. The repeater works by taking the signal sent out from any PowerG Sensor and sending it out a second time with just as much power and force as when it was first sent from the original sensor. By strategically placing the repeater, it's theoretically possible to double the useful wireless range of these sensors. That would mean that they can be used from up to 4,000 feet away from the IQ2+ in an open air environment. And if your building is particularly large, you may even have repeaters going away from the IQ Panel 2 Plus System in different directions, including up and down in building stories above or below.

But PowerG Sensors offer more than just an impressive wireless range. They are also known for their exceptional security. This is thanks to their military grade 128-bit AES encryption. To put this as simply as possible, the PowerG Sensor and the panel share a unique encryption key at the time of pairing. The sensor must provide this encryption key to the panel whenever it transmits a signal. Additionally, the panel must then provide a return response with the encryption key as verification in order for the command to go through. In the past, we have referred to this two-way communication process as a "digital handshake". Because of this encrypted pairing process, a PowerG Sensor actively knows whether or not it is currently paired with a panel. You may need to factory default a PowerG Sensor before you can pair it with a new system.


PowerG Sensors also take proactive measures against RF jamming. When a wireless sensor communicates with an alarm panel, it does so at a certain wireless radio frequency (RF). When we talk about RF jamming, we are referring to any malicious technique that prevents wireless signals from reaching their intended destination. This is accomplished by blocking the receiver with a stronger signal at the same wireless frequency as the device that is legitimately trying to communicate with it. When this is done on an alarm system, the system doesn't receive the incoming signals from faulted sensors, and no action is taken during a security breach or an unfavorable environmental condition. Early wireless sensors did not take this into account, and this made RF jamming an effective way to defeat an older wireless system.

The way that PowerG Sensors overcome RF jamming techniques is through a process called Frequency Hopping Spread Spectrum (FHSS). This process involves splitting the RF bandwidth into multiple channels. Each independent channel represents a unique radio frequency for wireless communication to occur. The transmitter (the PowerG Sensor) and the receiver (the alarm panel) both agree on a set of channel hopping sequences that will take place. These sequences are encrypted and time-based for them to occur seamlessly. Since the transmitter and the receiver are both synchronized, they can switch between channels very rapidly. A potential intruder would never be able to re-tun an RF jamming device to keep up. In the case of the PowerG Sensors, the frequency hops occur between 912 MHz and 918 MHz. There are 50 different unique frequency channels that are used, and frequency switches occur 64 times per second. More information on FHSS is available here.

One other benefit of PowerG Sensors that we have never discussed previously is their Adaptive Transmission feature that helps them conserve battery life. This is why you will often see a PowerG Sensor with a very long expected battery life, sometimes more than ten (10) years). Adaptive Transmission involves two-way communication between the PowerG Sensor and the alarm panel. The alarm panel will tell the PowerG Sensor how well its signal is being received. The PowerG Sensor can then adapt its outgoing signal so that it reliably reaches the panel, without expending too much energy. The sensor and the panel regularly exchange this information so that the ideal amount of energy is always used in signal transmissions. This saves battery life in the long run.

We have also found that PowerG Sensors are extremely easy to enroll and they offer the reliable and effective performance that you should expect out of your security system. We wholeheartedly recommend them for use on the Qolsys IQ Panel 2 Plus, as well as any other compatible alarm system. It is expected that the upcoming Qolsys IQ Hub will also be able to utilize PowerG Sensors, so look forward to using PowerG Sensors on that panel once it is available.


For now, if you have any questions about PowerG Sensors or the systems that support them, or if you are interested in signing up for new alarm monitoring service, then please reach out to us by emailing support@alarmgrid.com. We'll be available to check your emails from 9am to 8pm ET M-F. We look forward to hearing from you!

If you're using a newer wireless security system, then you will definitely want to explore the encrypted sensor options that we offer! Encrypted sensors are virtually impossible to hack, and they can make your security system even more secure. There are many great options available.

Honeywell sixminictpk5 a 5 pack of sixminict encrypted wireless

As you know, a home security system or a business security system is an investment you make for the protection of yourself, your property, and those around you. A proper system should also give you peace of mind and make you feel safe. It doesn't do you any good if an intruder manages to defeat your system. But with encrypted sensors, that is extremely unlikely to ever happen.

If you aren't familiar with encryption, it refers to techniques for encoding data and signals so that only authorized individuals and/or equipment are able to access the information. When it comes to wireless alarm systems, encrypted sensors send protected signals that can only be accessed, received, and interpreted by the authorized panel.

When wireless systems first rose to prominence, they rarely, if ever, used encryption. This made many people wary of wireless security panels, and they felt more secure using wired ones. The lack of encryption wasn't seen as a fatal flaw, as an intruder would have to be extremely savvy and really know what they're doing to defeat even a non-encrypted sensor. To this day, many people feel totally comfortable and safe using non-encrypted equipment. Remember, most intruders don't have the knowledge to beat wireless sensors, even if they aren't using encryption.

But there are the rare, professional criminals who do take the time to extensively study security equipment, and they develop techniques for beating non-encrypted devices. This is very uncommon, but it's not unheard of. And if you aren't using encrypted sensors, then you are leaving yourself open to this small risk. Whether or not that means outfitting your system with all-new encrypted sensors, or even upgrading to a different system that is capable of supporting encrypted sensors is up to you. We just want to make you aware of your options.

Today, we're going to briefly look at some popular wireless systems and explore their encrypted sensor options, as well as their non-encrypted sensor lineups. This will help you learn more about your system, or one you are considering for purchase.


Honeywell Lyric Controller

Honeywell lyric controller encrypted wireless security system


The Lyric represents the first the first encrypted panel from Resideo, formerly known as Honeywell. The system has its very own lineup of encrypted sensors called the Honeywell SiX Series Sensors. The lineup is a bit limited, as its lacking options like an outdoor door and window sensor and a curtain motion sensor. But the good news is that these sensors are extremely secure with their military grade 128-bit AES encryption.

You can supplement your SiX Series Sensors on your Lyric System with devices from the Honeywell 5800 Series. These sensors are not encrypted, but the lineup offers more diverse selection than the SiX Series lineup. You could consider using encrypted sensors for the most vulnerable parts of your home or office, while using non-encrypted 5800 Series devices for areas where it isn't as important. The non-encrypted 2GIG 345 MHz Sensors are also compatible with the Lyric once the system is on Firmware Version MR3 or higher.


Qolsys IQ Panel 2 Plus

Qolsys iq panel 2 plus verizon lte with powerg s line and legacy


There are some outstanding encryption options available for the Qolsys IQ Panel 2 Plus, regardless of which version you have. Any IQ Panel 2 Plus System can readily support DSC PowerG Sensors. Not only do these sensors have an outstanding wireless range of up to 2,000 feet away from the IQ Panel 2 Plus, they also utilize military grade 128-bit AES encryption and Frequency Hopping Spread Spectrum (FHSS) technology.

And if you have the 319.5 MHz Version of the Qolsys IQ Panel 2 Plus, then you can also pair Qolsys S-Line Sensors, which use rolling code encryption. This rolling code encryption isn't quite as secure as the encryption used by PowerG Sensors, but it still does a good job of keeping your system protected. The S-Line Sensors will also utilize encryption when paired with the original Qolsys IQ Panel 2. The original IQ Panel 2 cannot use PowerG Sensors.

In terms of non-encrypted options, each IQ Panel 2 Plus can support one of three (3) non-encrypted radio frequency signals. The available options are 319.5 MHz, 345 MHz, and 433 MHz, and it is dependent upon which version of the IQ Panel 2 Plus you buy. Again, it is certainly possible to mix encrypted sensors with non-encrypted sensors on the same system. But with the diversity and selection of the PowerG lineup, you probably won't need to look outside too much.


2GIG GC3e

2gig gc3e wireless encrypted alarm panel


The big highlight when the 2GIG GC3e was introduced was its ability to support encrypted sensors. While it took a little while before its encrypted sensor lineup became available, we were very pleased with the result. The 2GIG eSeries Sensors use highly secure encryption to keep your system protected. It also seems that 2GIG is regularly expanding upon this lineup, as we have been seeing new eSeries Sensors hit the market it recent times. All of the 2GIG eSeries Sensors are compatible with the GC3e, as well as its little brother, the GC2e.

With the GC3e, you also get access to the Honeywell 5800 Sensors and the 2GIG 345 MHz lineup. Just like with the Lyric, there is a bit more of a diverse selection of non-encrypted sensors available for the 2GIG GC3e. You can definitely set up a mixture of encrypted and non-encrypted sensors to meet the needs of your business. But with new 2GIG eSeries offerings continuing to become available, you shouldn't have much trouble building a fully encrypted 2GIG Security System.

As you may recall, Qolsys recently released Firmware Version 2.5.0 for the IQ Panel 2 and IQ Panel 2 Plus. One thing we forgot to explain in greater detail is the new ability for IQ Panel 2 users to receive temperature sensor alerts from Alarm.com. Alerts can be sent via email and/or text.

Qolsys iq panel 2 plus verizon lte with powerg s line and legacy

We posted awhile back about the inability for Alarm.com users to receive alerts regarding temperature sensor activity. This issue has now been addressed with Qolsys IQ Panel 2 Plus Firmware Version 2.5.0. While this doesn't fix the issue for other security systems, it does provide an effective solution for anyone using temperature sensors with the Qolsys IQ Panel 2 or IQ Panel 2 Plus. Being able to receive remote alerts from Alarm.com regarding temperature sensor activity can be very important in case of a broken HVAC system causing an overly hot or cool home.

The solution comes from the new Sensor Group - 25 Non-Reporting. This Sensor Group is available for use with environmental sensors, including any temperature, flood and freeze sensors. When a zone uses this Sensor Group, activating the associated sensor, will result in an alert being sent to Alarm.com, but not a central monitoring station. Alarm.com can then automatically forward the alert to the end user through text and/or email, depending on their notification settings.

If you are looking for a temperature sensor for a Qolsys IQ Panel 2 Plus, we generally recommend the DSC PG9905 Temperature Sensor. As a PowerG Sensor, the PG9905 will work with all versions of the IQ Panel 2 Plus. There are also various legacy RF temperature sensors available if you cannot go the PowerG route for whatever reason. If you have an original IQ Panel 2 System, then you will want to consider 319.5 MHz temperature sensors, such as the Qolsys IQ Temp.

Remember that you will need an alarm monitoring plan with Alarm.com service to start using the Alarm.com platform. Examples of compatible monitoring plans include the Gold and Platinum Level Plans from Alarm Grid (Self or Full). We offer free technical support for all Alarm Grid monitored customers, and we are happy to help you set up a compatible temperature sensor for your IQ Panel 2 or IQ Panel 2 Plus if you are experiencing difficulties. Just email us at support@alarmgrid.com. Our support hours run from 9am to 8pm ET M-F, so keep that in mind when emailing our support team. We look forward to hearing from you!

Hi DIYers! Today, we want to discuss an unusual quirk we found with Alarm.com. It turns out that the Alarm.com platform cannot receive alerts from temperature sensors. This is important for any Alarm.com user who wants to receive remote alerts for unusually high or low temperatures.


When you use sensors with a security system, the expectation is that you will be able to receive alerts from an interactive service platform whenever the device is activated. But with Alarm.com, the platform cannot receive incoming signals from a system regarding faulted Temperature Zones. This means that you cannot use Alarm.com to receive text and/or email alerts regarding an activated temperature sensor.

We discovered this issue due to a customer using a DSC PG9905 Temperature Sensor with a Qolsys IQ Panel 2 Plus System. We quickly discovered that the issue also applied to any temperature used with an Alarm.com Security System. This is important to note, as we know that many users out there will want to know about any unusual temperatures in their homes and businesses. Many people rely on using these sensors with their security systems so that they know if their HVAC systems break before serious and expensive damage occurs.

Fortunately, there is still another way you can receive alerts from Alarm.com regarding an unusually high or low temperature. If you pair a Z-Wave thermostat with your system, then you can set up notifications to be sent out whenever the detected temperature goes outside of a set threshold. A good Z-Wave thermostat to use for this application is an Alarm.com ADC-T3000 Thermostat. This thermostat also supports the ADC-S2000 Temperature Sensor, which will allow you to monitor the temperature in a second area of the building as well.

Another option is to use the Total Connect 2.0 platform with a Resideo Security System instead. Unlike Alarm.com, the Total Connect 2.0 service can be set up to send out text and/or email notifications for any sensor type, including temperature sensors. The Resideo LYNX Touch and Lyric Systems also have designed Temperature Zones that are used with Z-Wave thermostats to end high-low temperature alerts to AlarmNet360 and TC2 whenever an unusual temperature is detected. Just make sure that any Temperature Zone is noted as such on your central station document. These zones are frequently mistaken for 24-hour auxiliary medical zones.

If you have any questions about the functionality of temperature sensors, the Alarm.com and Total Connect 2.0 platforms, or any of our other products or services, please email us at support@alarmgrid.com. Remember that our support hours are from 9am to 8pm ET M-F. We also recommend checking out our monitoring page to learn more about our monitoring services. We look forward to hearing from you and providing top-quality monitoring service for your home or business.

UPDATE: This issue was later addressed in Qolsys IQ Panel 2 Plus Firmware Update 2.5.0. Please see this post for more information.

Hi DIYers! We know it has been awfully chilly out there lately. We thought it would be a good time to talk about freeze sensors and the benefits they provide. These devices are strongly recommended for anyone who lives in a colder area who wants to make sure their home is kept temperate.

Honeywell 5821 wireless temperature sensor and water sensor exte

Also called temperature sensors, freeze sensors alert a security system when the ambient temperature falls below a certain threshold. Usually, this is around 40 degrees Fahrenheit. That way, the user can take proper action to prevent their pipes from freezing. Remember, water freezes at 32 degrees Fahrenheit, and serious damage can occur if nothing is done in time. There are all sorts of horror stories of this happening while people are away for the day or on vacation.

Freeze sensors are particularly useful when used with an interactive service platform, such as Total Connect 2.0. These services will provide you with mobile alerts so that you will know if a situation occurs while you are away. Nearly every panel we sell can connect with one of these services. You just need the right communicator and monitoring plan.

While there are some standalone temperature sensors, freeze detection is often a secondary feature on a device. In fact, you might already have a device with freeze detection capabilities in your home and not even know it! The feature is commonly found on smoke detectors and flood sensors, so it never hurts to find out if your existing devices can also do freeze detection. For multi-function devices, freeze detection will usually operate on a specific Loop Number, and a unique system zone for freeze detection must be programmed.

If you're in the market for a new freeze sensor, you have plenty of options to choose from. The main thing to keep in mind is whether or not the device will work with your security system. If you are looking for a wireless sensor, then it must communicate at a compatible frequency. If you go the hardwired route, then your system must be able to support hardwired sensors. You might consider getting a smoke detector or a flood sensor that also includes the freeze detection function.

If you have a Honeywell or 2GIG System, then you likely use 345 MHz Sensors. The Honeywell 5821 is a convenient option for reliable freeze detection. You can also add a probe to have the 5821 Sensor double as a flood sensor. If you want a combination smoke and heat detector with freeze detection built-in, you might consider a Honeywell 5808W3.

For Interlogix Systems and the original Qolsys IQ Panel 2, you will want a 319.5 MHz Sensor. The Qolsys IQ Temp is a viable option. There's also the Interlogix TX-E611, which doubles as a flood sensor. For users also looking for a smoke, the Interlogix SDX-135Z also provides freeze detection.

If you have a Qolsys IQ Panel 2 Plus or a DSC PowerSeries Neo, then your system supports PowerG Sensors. In that case, you might go with the DSC PG9905. This sensor will offer the impressive range of PowerG, as well as extremely secure 128-bit AES encryption.

For users who want to go the hardwired route, the best bet is often to go with a smoke detector that includes the feature. We often steer customers towards 2-wire smokes, since they are easier to set up. A good option is the System Sensor 2WTA-B, which also includes a built-in sounder.
