Z-Wave has come a long way since its introduction in the early 2000s. From the original standard to Z-Wave Plus and Z-Wave Plus V2, each generation brings meaningful improvements to range, battery life, and performance. Now, Z-Wave 800-Series represents the most significant leap forward yet.

The Evolution of Z-Wave

To understand what makes the 800-Series special, it helps to look at how Z-Wave has evolved over the years.

The original Z-Wave protocol established the foundation for mesh networking in home automation, allowing devices to communicate with each other and extend the network's reach. Z-Wave Plus (500-Series) arrived around 2013 and brought improvements including 50% better range, 250% longer battery life, and faster processing speeds compared to the original standard.

Z-Wave Plus V2 (700-Series), released in 2018, pushed the boundaries further with additional range improvements, enhanced security through S2 encryption, and SmartStart functionality that simplified device pairing. The 700-Series became the go-to choice for premium smart home devices and earned a reputation for reliability and efficiency.

What Makes Z-Wave 800-Series Different

The Z-Wave 800-Series, built on Silicon Labs' latest chipset technology, takes everything that worked well in previous generations and improves upon it significantly. Here's what sets it apart:

Extended Range

The 800-Series delivers up to 1.5 miles of range in open air with Z-Wave Long Range (ZWLR) mode. While real-world performance in homes will vary based on walls, interference, and building materials, this represents a massive improvement over previous generations. For large homes, outbuildings, or properties with detached garages, this extended range can eliminate the need for additional repeaters.

Faster Communication

With improved RF performance and optimized protocols, 800-Series devices communicate more efficiently. Commands execute faster, and the mesh network responds more quickly to changes. This translates to snappier control when you're turning on lights, locking doors, or adjusting thermostats.

Better Battery Life

Battery-powered devices like door sensors, motion detectors, and smart locks benefit from the 800-Series' improved power efficiency. Manufacturers report battery life improvements that can extend the time between battery changes by months or even years in some applications.

Enhanced Security

Building on the S2 security framework introduced with Z-Wave Plus V2, the 800-Series includes hardware-level security features that make it even more resistant to tampering and unauthorized access. All Z-Wave 800 devices support S2 authentication out of the box, ensuring encrypted communication throughout your smart home network.

Backward Compatibility

One of Z-Wave's greatest strengths has always been backward compatibility, and the 800-Series continues this tradition. Your existing Z-Wave and Z-Wave Plus devices will work with 800-Series controllers and hubs. This means you can upgrade your system gradually without replacing every device at once.

Z-Wave Long Range Support

Perhaps the most exciting addition is native support for Z-Wave Long Range (ZWLR). This new mode allows point-to-point communication over much greater distances than traditional mesh networking. While standard Z-Wave mesh mode remains available for dense installations, ZWLR opens new possibilities for properties where devices are spread across larger areas.

Security Panels That Support Advanced Z-Wave Features

If you're looking to build a smart home system around a modern security panel, several options from Alarm Grid support Z-Wave for home automation control. These panels integrate security monitoring with Z-Wave device management, allowing you to control locks, lights, thermostats, and other smart devices from a single interface.

IQ Panel 4

The IQ Panel 4 represents IQ's (formerly Qolsys) latest generation of touchscreen security panels. It features built-in Z-Wave support for home automation along with PowerG sensor compatibility for long-range wireless security. The panel's 7" HD touchscreen makes it easy to manage both security and smart home functions from one central location. The IQ Panel 4 must be on version 4.4.0+ to support Z-Wave Long Range.

The IQ Panel 4 is available in multiple configurations:

• IQ Panel 4 AT&T LTE with PowerG/345 MHz
• IQ Panel 4 Verizon LTE with PowerG/345 MHz
• IQ Panel 4 AT&T LTE with PowerG/433 MHz
• IQ Panel 4 Verizon LTE with PowerG/433 MHz
  IQ Panel 4 AT&T LTE with PowerG/319.5 MHz
  IQ Panel 4 Verizon LTE with PowerG/319.5 MHz

2GIG Edge

The 2GIG Edge is a sleek, modern security panel that combines a compact design with powerful features. It includes Z-Wave support for home automation devices and offers advanced capabilities like facial recognition for touchless disarming. In order to support Z-Wave Long Range, the panel must be on firmware version 3.1.3.011+.

Available versions include:

• 2GIG Edge AT&T LTE
• 2GIG Edge Verizon LTE

Honeywell Home ProSeries PROA7PLUS

The First Alert PROA7 and PROA7PLUS are professional-grade security panels with optional Z-Wave support. Out of the box, they support ProSeries encrypted wireless sensors. With the addition of a PROTAKEOVER module, they can also support many legacy wireless sensors, and when you install the PROWIFIZW module, the system adds WIFI connectivity and support for Z-Wave home automation devices. When paired with Total Connect 2.0, you can arm, disarm, and control compatible devices remotely through the app.

At this time, the PROWIFIZW does not take full advantage of everything Z-Wave 800-Series offers, including Z-Wave Long Range. Thanks to Z-Wave’s backward compatibility, 800-Series devices will still work, but they’ll behave more like 700-Series devices when used with this controller. You still get solid Z-Wave performance today, and if Resideo updates the platform in the future, these newer devices should be well-positioned to benefit.

Options include:

• First Alert PROA7PLUS
• First Alert PROA7
• PROLTE-A2 - AT&T LTE Communicator
• PROLTE-V2 - Verizon LTE Communicator
• PROTAKEOVER Module
• PROWIFIZW WIFI & Z-Wave Module

2GIG GC Touch

The 2GIG GC Touch is another excellent option that combines security and smart home control. With its 7" high-resolution display and Z-Wave gateway functionality, the GC Touch provides a comprehensive solution that includes home security, home automation, energy management, and emergency monitoring.

Available in:

• 2GIG GC Touch AT&T LTE
• 2GIG GC Touch Verizon LTE

Compatible Z-Wave Devices

When building out your Z-Wave network, you'll find a wide variety of compatible devices available. Popular categories include:

Smart Locks – Z-Wave deadbolts and lever locks from manufacturers like Yale, Schlage, and Kwikset allow you to lock and unlock doors remotely, create temporary access codes, and receive notifications when doors are locked or unlocked.

Smart Lighting – In-wall switches, dimmers, and plug-in modules let you control lighting throughout your home. Many users create scenes that turn on lights when the system disarms or turn off all lights when arming at night.

Thermostats – Z-Wave thermostats like the Honeywell T6 Pro integrate with your security system to provide energy savings. You can automatically adjust temperatures based on whether the system is armed or disarmed.

Garage Door Controllers – Z-Wave garage door controllers let you open, close, and monitor your garage door status from anywhere. Get alerts if the garage door is left open or automatically close it when arming your system.

Water Valves – Smart water valves can automatically shut off your main water supply if a leak is detected, helping prevent costly water damage. This is a perfect example of how automation, working in conjunction with an alarm system, can save you money and prevent messy cleanup.

Making the Switch to Z-Wave 800

If you're starting fresh with a new smart home installation, choosing Z-Wave 800-Series devices whenever possible makes sense. You'll get the best performance, longest battery life, and most advanced security features available.

For those with existing Z-Wave networks, there's no need to rush out and replace everything. Backward compatibility means your current devices will continue to work as you gradually add 800-Series products. Over time, as you replace older devices, your network will naturally evolve to take advantage of the latest technology.

When shopping for Z-Wave devices, look for the Z-Wave 800 or "800-Series" designation on product packaging and specifications. As more manufacturers release 800-Series products, the selection continues to grow across all device categories.

Resideo announced this week that the 6148 keypad family is discontinued upon stock exhaustion. The official technical notification confirms that the 6148, 6148ICON, 6148EX, and 6148SP are all going away. If you need a similar, budget-friendly alternative look no further than the 6150.

The 6148 was never a glamorous keypad. It didn't have a touchscreen. It didn't talk to you. It was just a simple, reliable Fixed English keypad that did exactly what it was supposed to do. And honestly, that's what made it great.

The 6148 was the kind of keypad you could explain to your grandmother over the phone. You pressed buttons, the system responded, and that was that. No learning curve. No software updates. No wondering if the display would freeze. Back when touchscreens were still a novelty, most homeowners just wanted something that worked. The 6148 worked.

The 6148ICON was the same idea but with pictures instead of words. Little icons showed you what each button did. Some installers loved it. Others thought it was unnecessary. But it found its audience with customers who preferred visual cues over text.

The 6148EX added a tamper switch, which made it popular for commercial installations where someone might try to mess with the keypad. The 6148SP served Spanish-speaking customers. Each version filled a specific need in the market.

Now they're all going away because that's how this industry works. Parts become obsolete. Manufacturing priorities shift. Products that served us well for years eventually reach the end of their run.

The good news is that Resideo has recommended solid replacements. The Honeywell 6150 Fixed English Keypad takes over for the 6148, 6148ICON, and 6148EX. It has the same Fixed English display and basic functions, plus four dedicated function keys for quick arming and emergency buttons. The only thing missing is the tamper feature from the 6148EX, so keep that in mind if tamper protection matters to your installation.

For the 6148SP, Resideo suggests upgrading to the First Alert VISTAH3 system with the VISTAHPKP or VISTAHLKP keypads. These offer Spanish and Portuguese language support on a 2x16 alpha display.

If you're still running 6148 keypads on your VISTA system, now is the time to think about stocking up or planning your upgrade. Once the remaining inventory is gone, it's gone for good.

It's strange to get sentimental about a keypad. But the 6148 represents an era of alarm products that valued simplicity and reliability above all else. No apps. No cloud connections. Just a keypad on the wall that lets you arm and disarm your system. There's something to be said for that.

The alarm industry keeps moving forward. Panels get smarter. Keypads get touchscreens. Everything connects to the internet. That's progress, and it's mostly good. But every now and then, when a product like the 6148 gets discontinued, I think about how far we've come and what we've left behind along the way.

If you have questions about replacing your 6148 keypads or need help choosing the right option for your VISTA system, reach out to us at Alarm Grid. The best way to reach us is at support@alarmgrid.com. We're here from 9:00 AM - 8:00 PM EST Monday - Friday and we're happy to help you navigate the transition.

This post is a quick intro to the new 2GIG GC Touch, plus the top initial questions and answers circulating among dealers and forums. Documentation is still scarce at launch, so this post collects the most commonly asked questions we’ve seen and summarizes the early answers.

Caveat: This information is based on initial reports and community/dealer chatter about the GC Touch and may contain errors. Consider the Q&A below to be “early info” rather than final specs, we’ll update this post as more official documentation becomes available.

2GIG GC Touch:

Quick overview

The 2GIG GC Touch (Verizon LTE version and AT&T version) is positioned as a budget-friendly successor to the GC2/GC2e series: a modern touchscreen panel that retains broad backward-compatibility with legacy sensors but trims some premium features found on 2GIG’s flagship 2GIG Edge (Verizon LTE and AT&T LTE) model.

Early reports indicate the GC Touch emphasizes compatibility and value. It supports legacy 345 MHz sensors, adds support for encrypted 345S/eSeries devices, and improves wireless zone capacity over the old GC2 family.

Below are the top 20 questions installers and end users are asking right now, grouped by topic, followed by the current answers being reported. Again this is early info and may change.

Upgrading & Compatibility

1. Can I replace my old 2GIG GC2 or GC2e with the GC Touch?
   ○ Yes. It is designed as the direct "budget-friendly" successor to the GC2e series.
2. Will my existing 2GIG sensors (legacy 345 MHz) work with the GC Touch?
   ○ Yes, it is fully backward compatible with legacy 2GIG 345 MHz sensors and Honeywell 5800 series sensors.
3. Can I use my old GC2 power supply with the new panel?
   ○ No. The GC Touch uses a 14VDC adapter. You must swap out the old 12VDC transformer to avoid damaging the new unit.
4. Does the GC Touch fit the same mounting holes/backplate as the GC2?
   ○ It covers a similar wall footprint, but the backplate is new and must be replaced.
5. Will my old TS1 secondary keypad work with the GC Touch?
   ○ No. The legacy TS1 keypad is not compatible. You will need to use the Alarm.com app or a newer compatible secondary touchscreen. We don't currently know if one will be available.
6. Does it work with 2GIG eSeries (Encrypted) sensors?
   ○ Yes, it supports both the older non-encrypted sensors and the newer encrypted “eSeries” / “345S” sensors.

Features vs. 2GIG Edge

7. What is the main difference between the GC Touch and the 2GIG Edge?
   ○ The Edge is the “flagship” with Facial Recognition and a glass-to-edge screen. The GC Touch is the value model with a plastic bezel and no facial recognition.
8. Does the GC Touch have Facial Recognition disarm?
   ○ No, that feature is exclusive to the 2GIG Edge.
9. Does the GC Touch have Bluetooth disarming?
   ○ Yes, you can pair a smartphone to disarm the system automatically when you arrive home.
10. Does it have a built-in glass break detector?
    ○ No, the Edge has a built-in glass break; the GC Touch does not.
11. Does the GC Touch support Z-Wave Long Range (LR)?
    ○ It features the Z-Wave 800-series chip, which supports Z-Wave long range. However, the panel software must also support it, and it's unknown at this time if it does. Regardless, even without the addition of Z-Wave long range, the Z-Wave 800-series chip offers a significant improvement in range and speed over the older 500-series chip found in the GC2e.

Installation & Troubleshooting

12. What is the default Installer Code for the GC Touch?
    ○ 1561 (standard 2GIG default).
13. How do I reboot (power cycle) the panel without opening it?
    ○ Usually via the menu: Toolbox > Advanced > Reboot.
14. Why does the screen look different than my old panel? (Dark Mode)
    ○ The GC Touch introduces a “Dark Mode” UI that matches the 2GIG Edge style — a major visual change from the bright GC2 interface.
15. How do I add the new “345S” sensors?
    ○ With no installation documentation available, the exact process for adding sensors is not available. We'll provide full documentation as soon as it becomes available.
16. Does it support 5G cellular?
    ○ No. It uses an LTE (4G) communicator (AT&T or Verizon), which is standard for security systems today.

General & Smart Home

17. Can I view my Alarm.com cameras on the panel screen?
    ○ Yes, like the Edge, the GC Touch supports live view of compatible Alarm.com doorbells and cameras.
18. Does it work with Apple HomeKit?
    ○ Not directly. It integrates with Alarm.com, which can be bridged to HomeKit via Siri Shortcuts — there is no native HomeKit support on the panel itself.
19. How many wireless zones does it support?
    ○ Up to 128 wireless zones, which is double the capacity of the older GC2 (which maxed at 60).
20. Is there a secondary keypad available for it?
    ○ At launch, users are typically directed to use the mobile app, but a dedicated wireless keypad (like the 2GIG-PAD1-345) can typically be used for basic arming/disarming.

The 2GIG GC Touch looks to be a sensible, value-focused upgrade for GC2/GC2e customers. It has a modern touchscreen, broader sensor compatibility, and a big jump in wireless zone capacity, while intentionally leaving some flagship features (like facial recognition) to the 2GIG Edge.

Keep in mind this post compiles early reports and community feedback, so details may change as official documentation is released. Installers should confirm power, backplate, and keypad compatibility before a takeover, and end users should contact their alarm dealer for provisioning or account setup. We’ll update this page as 2GIG publishes final specs and installation guides so check back for the latest, and download this initial FAQ for a quick reference.

Resideo Technologies has announced an automatic firmware update rollout for several AlarmNet LTE communicators used in security systems. These updates are designed to enhance cellular connectivity and ensure a more stable, reliable link between your system and the AlarmNet cellular network.

According to MyWebTech Technical Notification #136, Resideo will begin pushing firmware updates over the air within the next 30 days to select radios used in burglary and residential fire applications. These updates are part of an ongoing effort to maintain optimal performance and address prior cellular connectivity issues.

Affected Radios & Latest Firmware Versions

• Honeywell Home LTE-IV — Firmware 4.1.31.0
• Honeywell Home LTE-IA — Firmware 4.1.31.0
• Honeywell Home LTE-XV — Firmware 4.0.62.0
• Honeywell Home LTE-XA — Firmware 4.0.62.0
• Honeywell Home LTE-L3V — Firmware 4.0.54.0
• Honeywell Home LTE-L3A — Firmware 4.0.54.0
• Honeywell Home LTE-HSV — Firmware 2.14.16

Many of the affected communicators, though still active in the field, have been discontinued by Resideo and AlarmNet. Because they are no longer offered by Alarm Grid, discontinued products are not linked above.

These updates will occur automatically, and no action is required from end users in most cases. However, communicators with low backup battery voltage, or with a missing backup battery, may not successfully complete the update. In those instances, the communicator battery should be replaced so that the update can occur.

A small number of systems may briefly display a “radio trouble” condition when the communicator reboots after the update. This condition can typically be cleared by entering a valid user code + 1 (Off) twice on the system keypad.

Notes on Fire Radios

The same technical notice also reminds users about firmware updates for certain commercial fire communicators (HWF2V-COM, HWF2A-COM, LTE-CFV, LTE-CFA). However, Alarm Grid does not support commercial fire alarm systems, and these devices are not sold or supported by us. If you work with fire alarm communicators, contact your fire system provider or Resideo technical support for further assistance.

Summary

Resideo’s automatic update process ensures continued reliability for AlarmNet-connected communicators. As long as your communicator is in good working order and has adequate power and a good backup battery, it is likely that no action will be required on your part. With a possible exception of a disarm command to clear a communicator trouble display on some VISTA systems.

Alarm Grid will continue to keep you informed of any further changes that may affect system performance or connectivity.

We first told you about the new lineup of First Alert CX4 cameras in September. At that time, there wasn't much information available about the cameras and their specs. Now, Resideo has announced the release of the cameras and mounting accessories. So, let's take a closer look at them.

Each camera in the new CX4 lineup offers 8MP ultra-high-definition image quality. Intelligent AI-based event detection can distinguish people, vehicles, animals, and packages. The main differences between the various camera styles come down to design, mounting style, and placement options. Below is a quick reference table showing how each camera fits into your installation plan, along with the compatible accessories for that model.

Back in 2019 we told you about the Lyric Gateway's end-of-life. Recently we found that an unregistered Lyric Gateway can't be activated. This is because of a disconnect between AlarmNet360, the platform used to register, and the panel. If you have a registered Gateway, you are not affected.

Since the Lyric Gateway hasn't been available since 2019, this is likely not an issue that will affect a lot of people. But, since the secondary market for alarm panels is alive and well on platforms like ebay, and because the Lyric Gateway can't be programmed through the panel's touchscreen, it's still necessary to get this information out there.

When Resideo discontinues a product, they continue to fully support that product for five (5) years, then it moves to limited support. That means Resideo will only provide written documentation for the product to anyone requesting support. They will not provide over-the-phone troubleshooting.

Between 2019 and now, if we had an issue with a Lyric Gateway not registering properly, we could contact Resideo technical support and they would assist with the registration. Their support team has access to tools that we don't and can resolve some issues with registration that we can't. However, now that the Gateway has entered limited support, Resideo tech support will no longer offer this assistance.

So, if you see a Lyric Gateway for sale in some secondary marketplace, we recommend you give it a pass. If you have an unregistered Lyric Gateway with any SIX Sensors paired with it, you'll need to take special steps to keep those sensors viable for use with a new panel.

1. Be sure sensors are powered on. Be sure that every SIX sensor that is paired with the Gateway panel is powered on and within range of the panel.
2. Default the Lyric Gateway When you're ready to move the SIX sensors to a new First Alert PROA7, PROA7PLUS, or VISTAH3 panel, remove the set screw in the bottom edge of the panel, then either pull the rear cover off, or pull the panel away from the rear cover (if wall mounted). This will expose the battery, RJ45 port, and the microswitches on the back of the panel.
   • For Rev. 1.00 panels, reboot the panel. To do so, using a paper clip or similar small tool, depress the center microswitch on the back of the panel (see image below) until the panel reboots. Once the panel boots back up, you have five (5) minutes to complete the default. Otherwise, you'll need to reboot again.
   • For Rev. 1.01.0215.531+ you can skip the power cycle and move straight to Step 3.
3. Perform the default. On the rear of the panel, just below the RJ45 Ethernet port you'll see three microswitches. As you face the back of the panel use a small tool, paper clip, or similar item to press and hold down the left switch for twenty seconds, or until the panel prompts you to enter the Installer Code. After twenty seconds, or once prompted for the Installer Code, release the switch. If prompted for the code enter the panel's current Installer Code. This will set the panel back to factory defaults. As part of the default, a signal will be sent from the panel to all SIX sensors releasing them so that they are no longer paired. All SIX sensors previously programmed with the panel that receive this message are now free to be paired with a new panel.

Any paired SIX sensor that doesn't receive a release signal from the panel, either by the sensor being removed via AlarmNet360 or by defaulting the panel, will be unable to pair with a new panel.

It was a crazy day across the internet. Like a lot of other websites you might use, Alarm Grid was affected by the disruptions from the outage at Amazon Web Services (AWS). We wanted to let you know what happened, how it affected us, and the good news that things are getting back to normal.

What Happened?

According to Amazon, at around 3:11 AM EDT Amazon's huge AWS US-EAST-1 region (which is a massive data center in Virginia) started having issues. The first signs of trouble were increased latencies and error rates for sites and applications serviced by US-EAST-1. This regional data center runs a huge portion of the internet, so when it has a bad day, it can create a domino effect that takes down lots of services.

The crux of the problem appears to have been two-fold. Early in this event, at around 5:00 AM EDT, Amazon identified an issue with DNS resolution to the DynamoDB endpoint within the US-EAST-1 region. DNS or Domain Name System is how a URL like alarmgrid.com gets tracked down to its source IP address. By 6:35 AM EDT, Amazon reported that this issue had been fully mitigated.

The second source of trouble has to do with an underlying system designed to monitor the health of AWS load-balancing servers. It's unclear exactly what happened with this system currently, but mitigation efforts are progressing well for that issue as well. You're likely still seeing latency with some sites and apps that you visit. At 4:03 PM EDT, the AWS Health Dashboard said:

"Service recovery across all AWS services continues to improve. We continue to reduce throttles for new EC2 Instance launches in the US-EAST-1 Region that were put in place to help mitigate impact. Lambda invocation errors have fully recovered and function errors continue to improve. We have scaled up the rate of polling SQS queues via Lambda Event Source Mappings to pre-event levels. We will provide another update by 1:45 PM PDT."

How Did This Affect Alarm Grid?

Alarm Grid uses AWS in several ways to keep our website and services running smoothly. When AWS went down, it meant we had trouble with:

• Access to our site: The site alarmgrid.com has been unavailable at times, throughout the day today.
• Website features: You might have noticed our site was super slow, or that parts of our customer portal weren't loading at all. If you are attempting to place an order, you may see some issues. Please, retry any failed operation. You can reach out to support@alarmgrid.com if you need assistance.
• Our own support tools: Our web-based phone system was affected earlier in the day, but seems to have recovered as of now.

We know how frustrating this is, especially when you're trying to get something done. We sincerely apologize for the headache. Our site is up, but is still experiencing significant latency as of this writing. Rest assured, we're here and we'll help however we can.

Good News: Things Are Coming Back Online!

As of this afternoon, AWS says they've identified the issue and are well on their way to a resolution. We're already seeing our systems come back to life, and the Alarm Grid site should be getting back to normal.

What Wasn't Affected

Fortunately, monitoring services were apparently unaffected. We received no reported issues from our central station partners: Criticom Monitoring Service for customers in the United States, and Rapid Response for our Canadian customers. Alarm signal processing continued as usual. Likewise, the Total Connect 2.0 and Alarm.com remote services also appear to have been unaffected.

A Few Quick Stats on the Outage:

Just to show how big this outage was, at its peak, Downdetector.com showed nearly ten thousand reports for AWS. It also caused problems for major services like Snapchat, Ring, Roblox, Fortnite, and many others.

Due to an ongoing strike by the Canadian Union of Postal Workers (CUPW), the delivery of packages through Canada Post is currently suspended. As a result, Alarm Grid will temporarily use UPS to fulfill all Canadian orders until postal service in Canada resumes. It's unclear how long that may be.

This measure ensures that Canadian customers continue to receive their equipment and supplies without unnecessary delay. When we ship international orders, the cost of shipping is calculated at checkout, based on the postal code of the delivery address.

Once the strike is resolved and regular Canada Post operations resume, Alarm Grid will revert to our usual shipping methods for Canadian customers. You can check back here for an update as soon as that happens.

The Resideo PROSIX line of wireless sensors currently works with the PROA7, PROA7PLUS, and VISTAH3 panels. These encrypted sensors offer excellent range, reliability, and security. But to get the most out of your investment, it helps to follow some basic rules for installation and upkeep.

New to PRO Series sensors? This simple guide shows you how to place, pair, and care for Resideo PROSIX devices with your PROA7 or PROA7PLUS panel.

What To Do First

1. Plan install locations: Walk your home and decide where each sensor should be mounted. We'll talk more about mounting considerations next.
2. Name your zones: Make a short list like “Front Door,” “Kitchen Window,” “Hall Motion.” This makes setup quick and easy.

Sensor Placement Basics

Door/Window Contacts

• Protect any opening a person can reach from outside. If you’re on a budget, start with the highest-risk spots: ground-level doors and windows, especially those at the back of the home or in darker, hidden areas. Cover additional openings as your budget allows.
• Mount the sensor on the frame and the magnet on the moving portion of the door or window.
• Keep the magnet and sensor properly aligned and as close together as possible when closed. Check your model’s maximum gap specification and make sure the closed gap doesn’t exceed it.
• Avoid mounting directly on ferrous metal. If the frame is metal, use included spacers if provided. Aluminum doors usually don't pose a problem. A PROSIXCTV can be used to add a separate contact, such as the Honeywell 947-75T, that is made specifically for mounting on steel doors.

Motion Sensors

• Place on a wall or in a corner with a clear view of the room, about 6–8 feet high.
• Avoid pointing at windows, fans, or HVAC vents.
• Do not aim directly at heat sources (ovens, space heaters, sunny glass).
• If you have pets, follow the specific mounting instructions in the installation guide. The PROSIXPIRV offers up to 80 pound (36kg) pet immunity when the instructions for pet immunity are strictly followed. Generally speaking, mount where any animal, regardless of size, can't come within six (6) feet of the front of the sensor.

Glass Break Sensors

• Verify in the installation instructions that the PROSIXGB is suitable for the type and size of glass you want to protect.
• Mount the PROSIXGB in the same room as the glass to be protected.
• Avoid thick curtains or heavy drapes between the sensor and the protected glass.
• Set the sensitivity level for the PROSIXGB based on the distance between the detector and the protected glass.
• Mount on a wall or ceiling with a clear “line of sound” no more than 25' (7.6m) from the protected glass.

Tip: If you’re unsure about a mounting location, temporarily tape the sensor in place, finish setup, and test the glass break before permanently mounting.

How to Pair a PROSIX Sensor

1. On the panel, tap Menu (≡) > Tools > Installer Code (Default 4112) > Programming > Peripherals > + Key (upper right). The panel is now in listening mode.
2. Put the sensor into enrollment by pulling the battery tab on brand new sensors, or by opening the device's cover to activate the tamper.
3. Once the panel detects the sensor, give it a clear name, such as “Front Door” or “Living Room Motion.” Program any other sensor-specific fields, such as Response Type and Service for sensors that can use more than one zone, e.g., PROSIXCTV and PROSIXSMOKEV. For sensors with a single function Service will be filled automatically.
4. Be sure to click Save and close the sensor cover if the tamper was used to pair it with the panel.
5. Once you exit programming tap Menu (≡) > Sensors and check the signal strength of each PROSIX sensor in the location where it will be permanently mounted. Once a good communication path is confirmed, permanently mount each sensor and do a final signal strength check.

Important Note: If a sensor won’t enroll, confirm it isn’t paired to another panel. An unpaired sensor shows a rapidly blinking LED when you pull the battery tab, fault the sensor, or open the cover. A slow blink indicates the sensor is already paired. If possible, factory-default the sensor; otherwise, remove/release it from the previous panel, then enroll to the new one.

Battery Care

• Use only the battery type listed on the sensor’s Install Guide, or Data Sheet.
• Always remove all batteries, wait a full ten seconds, then insert new batteries. This helps to clear any low battery signal. Always read the sensor instructions for any special notes about installing new batteries. For example, the PROSIXCMBOV requires that all new batteries be installed within 15 seconds of beginning the battery install process.
• For sensors with multiple batteries, always change all batteries at the same time. Don't mix old and new batteries and don't mix batteries from different manufacturers.
• You can check the battery level of other sensors by tapping Menu (≡) > Tools > Installer or Master Code (4112 and 1234 by default, respectively) > System Test > Test Sensors > Start Test > OK. The siren will sound for a few seconds. Go around and fault each sensor. Then check the panel for the signal strength and battery level of all tested sensors. If any other sensor batteries are low you can go ahead and change them to prevent future low battery messages on the panel.

Important Note: PROSIX sensors use two-way supervision, meaning they require an acknowledgement (ACK) from the panel after sending a check-in signal. If the panel is powered down or removed, a sensor will repeatedly attempt to check-in, quickly draining its battery. To preserve battery life, remove the batteries from your PROSIX sensors whenever the panel will be out of service for an extended time.

When powering the system back up, always power on the PROSIX transmitters before the PRO Series panel. The panel uses Frequency Agility to select the best RF channel and then instructs the sensors to follow. If the panel changes channels while the sensors are still off, they won’t receive the update. This leaves them in a state of limbo, unable to communicate with the current panel or with any new or defaulted panel.

Monthly Test

1. Put the system in test mode with your monitoring company if you subscribe to full monitoring. You'll need to provide your name, address, and false alarm password, as well as a duration for the test.
2. Enter the panel's Walk Test Mode.
3. Open and close each protected door/window and confirm it shows on the panel.
4. For motion detectors, follow the sensor's instructions for entering Walk Test Mode. For the PROSIXPIRV remove and replace the batteries. This removes any transmit inhibit designed to conserve battery life and enables the sensor LED. The motion will remain in Walk Test Mode for ten minutes. Walk in front of each motion sensor and verify you see it trigger when you walk in the protected area.
5. For glass break sensors, we linked above to an FAQ on using the Honeywell FG701 to perform a functional test. The FAQ is written describing the steps with a Honeywell 5853, but they translate to the PROSIXGB very well.
6. Exit test mode and confirm the system displays the proper status with no trouble conditions present.

Safety and Mounting Tips

• Use the included screws for permanent installs where possible.
• Clean the mounting surface before using double-sided foam tape. Press firmly in place for a full 30 seconds.
• Keep sensors dry and indoors unless the model is rated for outdoor use.

Quick Reference: Which Sensor Goes Where?

Keep Your Panel Updated

Connect your panel to WIFI so it can receive the latest over-the-air (OTA) firmware updates. The PRO Series panels will not download firmware using cellular data. The PROA7PLUS comes from the factory with the PROWIFIZW installed. The PROA7 comes with no built-in communicator, so it will need to have a PROWIFI or PROWIFIZW added.

Firmware updates can improve stability and sensor compatibility. When firmware updates for PROSIX sensors are available, they are included in the panel's firmware package. Once the panel updates, the sensor firmware will be pushed by the alarm panel to each sensor.

Update 12:30 PM EDT: Total Connect 2.0 Email Notification Issue Resolved

This morning, Resideo identified and resolved an issue that was affecting Total Connect 2.0 email notifications. The temporary problem was caused by a third-party vendor, Mailjet, and may have prevented the delivery of system notifications, password reset emails, and welcome messages.

Apparently, the undelivered email messages were queued, and when service was restored these messages went through. This may cause some Total Connect 2.0 notifications to arrive out of sequence until all queued messages are delivered. Any time you receive a notification that you question, log into Total Connect 2.0 and check the Activity screen as well as the current status page. You can also check the panel's Event Log from the touchscreen by tapping Menu (≡) > Events.

Who Was Affected?

The service disruption was reported at approximately 8:44 AM EDT. If you were expecting an email from Total Connect 2.0 this morning and did not receive it, you were likely affected by this brief outage.

Why Redundancy Matters

This incident highlights the importance of enabling multiple notification methods. We strongly recommend setting up push notifications on your mobile device as a reliable backup. For customers affected by today's email issue, push notifications would have still been delivered successfully, ensuring no critical alerts were missed.

As of approximately 12:30 PM EDT the issue has been resolved. If you're an Alarm Grid monitored customer and you continue to have any issues receiving email notifications for TC2 alerts, you can contact our support team by calling 1-888-818-7728, M - F 9:00 AM - 8:00 PM. You can also email us at support@alarmgrid.com.
