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. Check out our alarm monitoring plans while you're at it.

Thanksgiving is here once again! The Alarm Grid offices will be closed on Thursday, November 27th, so our team can enjoy time with their families. Our office will be open and back to normal hours on Friday, November 28th, at 9:00 AM EST. Despite our office being closed, central station monitoring will be handled as it always is; quickly and professionally.

Monitoring Station Contact Information

Even though our office is closed, your security system keeps working around the clock. Our central station partners at Criticom Monitoring Services (CMS) and Rapid Response will be monitoring systems and responding to alarms all day Thursday. We appreciate their professionalism and commitment to keeping our customers safe.

If you need to contact the monitoring station during the holiday to report a false alarm or put your system on test mode, here's who to call:

US Customers: Call CMS at (888) 818-7728 and press Option [9]. Have your name, address, and false alarm password handy when the operator picks up.

Canadian Customers: Call Rapid Response at (800) 932-3822 with your name, address, and false alarm password ready.

Quick heads-up: Make sure you give them the correct information. If you accidentally provide an incorrect password or your Duress password instead of your false alarm password, they'll dispatch help. Because that's exactly what the Duress password is designed to do.

For Technical Support - Email Us Instead

Here's something important: the monitoring station only handles alarms and emergencies. They can't help with technical issues, programming questions, or changes to your account settings like zone names or contact lists.

For anything like that, shoot us an email at support@alarmgrid.com. We'll get back to you as soon as we're back in the office. The holidays sometimes create a bit of a backlog, so thanks in advance for your patience when we return!

Thanksgiving Safety Tips

If you're traveling for Thanksgiving, please be sure to arm your system before you hit the road. Also, double-check that you know your false alarm password before you leave. Nothing says "happy holidays!" quite like realizing you can't remember your false alarm password while you're three hours, or even three states away.

If you're cooking this year, kitchen smoke and steam are notorious for setting off smoke detectors. If yours is connected to your alarm system and it goes off, just silence it quickly. For all-in-one panels like the IQ Panel 4 or PROA7PLUS, you'll see a prompt on the screen asking for your disarm code. For older VISTA systems, just enter your User Code and press 1 (Off), exactly like you're disarming the system.

The monitoring station will call you when a smoke alarm goes off. If it's just your burning turkey setting off the detector (we've all been there), let them know and give them your false alarm password. They'll ask some questions to make sure everything's okay, and you can decide together whether the fire department really needs to stop by.

Important: Carbon Monoxide Alarms

If your carbon monoxide (CO) detector goes off, get everyone out of the house immediately. Carbon monoxide is completely invisible and odorless, and it's dangerous - especially for little ones, like kids and pets.

The monitoring station is required to send help on CO alarms no matter what. Even if you call them and say you're fine, they're still dispatching the fire department. It's for your safety. The fire department has special equipment to detect carbon monoxide and make sure your home is safe to re-enter.

Happy Thanksgiving!

Thank you for choosing Alarm Grid. Whether you're hosting, traveling, staying home for a quiet day, or working through the holiday, we hope your Thanksgiving is exactly what you want it to be. May your turkey be moist, your family drama be minimal, and your smoke detectors stay silent!

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.

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.

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.
