October 2025 Archives

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.

We appreciate your patience and understanding while this situation unfolds. Our team is monitoring the developments closely and will continue to prioritize fast and reliable delivery for all of our customers.

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.
