Here at Alarm Grid, we try to help as many people as possible with their alarm system. Sure, we hope it will lead folks to choose us for their alarm monitoring needs. But it's also because we're simply helpful people. An alarm in your home or business should help quell fears, not cause them.

We've begun what I think of as "Silly Season". You may be familiar with this term from Nascar, but for us in the alarm industry, this is the time when a lot of home buying and selling occurs. During this time, we get a lot of calls that go something like this, "I just moved into a home with an existing alarm. We haven't been using it, but somehow it got armed, and now it's going off, and I don't know the code to disarm it. Please help!"

Moving into a new home is exciting, but it's also stressful and can be overwhelming at times. So, I've (Ms. Manners) put together this guide to help you, the person who moved out of the home in this scenario, to leave behind your alarm system in a way that's as stress-free as possible for all parties involved.

Ms. Manners Says: Notify Your Alarm Company

If your alarm system is monitored, be sure to notify your alarm company that you are moving out and that the system is staying behind. This may seem obvious, but many people assume that if they stop paying their monitoring fees, the alarm company will know they no longer want service and will cancel it on their own. This is not the case for a number of reasons! There may be contracts involved. There could be liability issues. So for many reasons - not the least of which is it's the polite thing to do - any time you wish to stop monitoring service to a particular address, you should notify the alarm monitoring company as soon as possible.

By notifying the alarm company, you do several things. You give them an opportunity to reach out to the new homeowner and introduce themselves. Hopefully, if you've had a good experience with your monitoring company, you will also put in a good word about them to the new homeowner. Both of these things give the company a leg-up when it comes to courting a potential new customer, and it also gives the new homeowner information based on your real-life experience, not just an advertisement in a new homeowner's mailer.

By notifying the monitoring company, you can also help to prevent any unnecessary dispatching of the authorities to this address. As bad as the scenario above is for the poor, uninformed new homeowner, it's worse for the police, fire, or EMS personnel who may respond to the alarm, which we know is false.

Remember, the person who signed up for the monitoring service at the address in the scenario above no longer lives there. That means the monitoring station is going to be calling people who have no idea what may be going on at this address (which is also an annoyance for the person receiving the call). In this situation, it is likely that the monitoring station MUST dispatch because if they don't (and there is some type of emergency) there may be repercussions for them. A monitoring station is always going to adhere to the adage, "Better safe than sorry." After all, safety is their business.

Ms. Manners Says: Default Users, But Not Zones

When you sell a house and the alarm system with it, you may think it's a good idea to set the alarm system back to factory default to allow the new homeowner a chance to program it as they see fit. Resist this urge! In most cases, what was your Front Door is now going to be their Front Door. What was your Kitchen Window is now going to be their Kitchen Window. John's Bedroom Window may become Jane's Bedroom Window, but this is a pretty simple thing to change and doesn't really call for the entire system to be set back to factory default.

When it comes to user codes, though, it is best to set these back to factory defaults. This will prevent the new homeowner from finding out what codes you used. After all, we are creatures of habit, and there's a good chance you'll use those same codes in your next system. Also, if you set the codes for the Installer and Master users back to their default, the new homeowner should easily be able to find out what they are by doing a quick search online. Then, if they find themselves in the messy scenario discussed above, they'll be able to get themselves out of it. Being able to get yourself out of a jam like this one can do wonders for your self-confidence.

System Manufacturers and their Default Codes

Use the information in the table above to set the codes in your panel back to their default values. If you don't see your panel listed, you can likely find the information you need with a quick online search. Performing this process is the single most helpful thing you can do for the new homeowner when it comes to the alarm system!

Ms. Manners Says: Leave Behind Good Notes

Any information you know about your alarm system, such as the manufacturer and model, the default installer code, and the default master code - each of which hopefully you have programmed into your panel by this time - will be helpful for the new homeowner. A list of zone numbers and their descriptions is also very much appreciated by a new homeowner. Leave them a note, tucked behind the keypad, or on a kitchen counter. Give them the sequence of keys to enter to disarm the system, or better yet, if you have the opportunity, show it to them, and then leave them a note to back up your demonstration.

If you're willing, leave them your contact information so they can contact you in the event that something unforeseen comes up. This is particularly important if your system is somewhat complex and has multiple home automation features integrated with it. I promise the last thing the new homeowner wants to do is bother you if they can avoid it. Everyone at Alarm Grid has talked with a frantic new homeowner who never even considered contacting the prior homeowner. It's usually something we suggest if we're unable to assist.

Fortunately, in most cases, we are able to assist, and we are happy to do so. This is just one of the many ways we make new friends here at Alarm Grid! I hope that anyone who is preparing to move out of a home and leave behind an alarm system will read this and use these suggestions to prepare.

If you happen to be moving into a home that already has an alarm system, and perhaps the previous homeowner didn't read this post, feel free to reach out to us. We're here Monday - Friday from 9:00 am to 8:00 pm Eastern Time. You can reach us via email, or by calling 888-818-7728.

While many alarm panels have been outfitted with LTE cellular communicators to accommodate the 3G and CDMA Sunset, one system that is being left behind is the Honeywell L5100. Luckily, we have two (2) great panel upgrade options if you want to continue receiving cellular alarm monitoring.

Without getting too in-depth, the 3G and CDMA Sunset will leave the Honeywell L5100 with no functional cellular communicator option. This is because any Honeywell GSMVLP5-4G units that are currently activated for monitoring service will stop working once the associated AT&T 4G Network is shut down. If you are still using a Honeywell L5100 with a GSMVLP5-4G for cellular monitoring, then it is crucial that you upgrade to a new system as soon as possible. This is the only way that you can continue receiving cellular monitoring service. Remember, cellular connectivity represents the most reliable communication path available for an alarm system. We strongly urge you to not wait until the end of the 3G/CDMA Sunset.

Unless you have some specific knowledge of security systems, then you may have trouble determining which alarm panel you should get to replace your Honeywell L5100. That is where we are able to help. We have two (2) recommended systems if you are needing to upgrade. Both of these system options will allow you to continue using the majority of your existing sensors, and they will provide some great new features that you can take advantage of. We will briefly discuss both of these options so that you can make an informed decision.

Honeywell Lyric

If you want to stick within the Honeywell banner, then the Lyric is a great option. It has two (2) excellent LTE cellular communicator options in the Honeywell LYRICLTE-A AT&T LTE Communicator and the Honeywell LYRICLTE-V Verizon LTE Communicator, and it can readily support all of the one-way Honeywell 5800 Sensors used with the L5100. This system is preferred by users who want to continue using Total Connect 2.0, as well as any Honeywell IP Cameras. The makes the Lyric the go-to option if you are currently using security cameras with your L5100. The Lyric is also preferred if you are a regular iOS user, and you want to integrate your security system with your Apple HomeKit Network.

Qolsys IQ Panel 2 Plus 345 MHz

For L5100 users who don't necessarily feel married to Total Connect 2.0, and who also don't really care about HomeKit compatibility, jumping ship to a different manufacturer is an option. The Qolsys IQ Panel 2 Plus 345 MHz is hard to ignore. It can also support your existing one-way Honeywell 5800 Wireless Sensors right out of the box. You will need to make the switch from Total Connect 2.0 to Alarm.com, but this transition is fairly seamless if you don't have cameras set up. And while the IQ2+ might not have HomeKit, it does offer its own unique benefits like Z-Wave Plus functionality, automatic Bluetooth disarming, and partitioning support. You won't find any of those features on the Lyric. Just remember to choose the 345 MHz IQ2+ in the silver and white box to continue using your old Honeywell 5800 Sensors.

We're Here to Help!

There isn't a truly one-size-fits-all solution for existing Honeywell L5100 users. For some, the Lyric is the best option. But other users can get more mileage out of the Qolsys IQ Panel 2 Plus 345 MHz. Although we gave you some general guidelines and considerations above, you may still want some more advice on which move to make. Our security system planners are happy to help you determine which system is right for you.

Upgrading early is the best way to ensure that you do not experience any interruptions in your monitoring service. If you are a Honeywell L5100 user looking to plan for the future, feel free to email our team at support@alarmgrid.com. We will check your email during our usual business hours of 9am to 8pm ET and respond back at our earliest opportunity. We look forward to helping you plan out the long-term security solution for your home or business!

We have made a discovery regarding the compatibility for the Honeywell L5100-WIFI for LYNX Touch Systems. It turns out that L5100-WIFI units with the updated MAC prefix of B82CA0 can be used with Honeywell L5100 Systems running a firmware version of at least 5.00838, but less than 5.05000.

If you aren't familiar with the Honeywell L5100-WIFI, it is an internet communicator that allows a compatible Honeywell LYNX Touch Panel to communicate with the Resideo AlarmNet Servers across an IP (internet protocol) network. The L5100-WIFI accesses the internet by connecting with a local WIFI network. Many users rely on the L5100-WIFI for inexpensive IP monitoring service. The communicator can also be used to set up the LYNX Touch System with Total Connect 2.0, provided that the user's alarm monitoring plan includes access to the platform.

If you recall back in the summer of 2018, it was announced that new Honeywell L5100-WIFI units had an updated MAC prefix, as it was changed from 00D02D to B82CA0. This had several implications. Starting with LYNX Touch Firmware 5.05000, Resideo locked the required MAC prefix so that only L5100-WIFI units with 00D02D were supported. This was later revised in Firmware Version 8.00183 to support the new MAC prefix of B82CA0. As a result, LYNX Touch Systems with a Firmware Version of at least 5.05000, but less than 8.00183, cannot support newer L5100-WIFI units with the MAC prefix of B82CA0. For LYNX Touch firmware in Canada, the required MAC prefix of 00D02D became locked with Firmware Version 5.15000.

However, we didn't realize that LYNX Touch Systems running firmware versions below 5.05000 (and below 5.15000 for Canadian models) do not have the locked MAC prefix requirement. This means that if you have a Honeywell LYNX Touch System with a firmware version of less than 5.05000, then you can use it with a newer L5100-WIFI unit with a MAC prefix of B82CA0. It still must meet the minimum firmware requirement to support the L5100-WIFI (Firmware Version 5.00838), but this allows for some new monitoring possibilities. Most notably, it allows certain Honeywell L5100 units use either the new L5100-WIFI model with the updated MAC prefix or the old model with the old MAC prefix.

In spring of 2019, it was announced that Resideo was no longer allowing Honeywell LYNX Touch Panels to receive over-the-air (OTA) firmware updates. Instead, firmware updates could only be applied locally using the Honeywell LYNXTOUCH-MSD Firmware Updater Tool. Initially, the updater tool was only compatible with the Honeywell L5210 and Honeywell L7000, but it was later made compatible with the Honeywell L5200 as well. But the updater tool was never made compatible with the Honeywell L5100. This makes it impossible to update the firmware for a Honeywell L5100 Security System, and there is no way to get the system onto Firmware Version 8.00123 or higher.

But since Resideo didn't begin locking the required MAC prefix to 00D02D until 5.05000, an L5100 running a firmware version of at least 5.00838, but less than 5.05000, can support all L5100-WIFI units, regardless of their MAC prefix. Therefore, if you have an old Honeywell L5100 System lying around that you were thinking could never be monitored again unless you found a used L5100-WIFI with the old MAC prefix, it may be a good idea to check its firmware to see if it falls in that range.

If you want to check the firmware for a Honeywell L5100, you can do so by choosing Security > More > Tools > enter your Master Code (default 1234) > Test. The firmware revision will be displayed at the top of the screen. This process is the same for any LYNX Touch System, so you can also use this method to check your L5200, L5210, or L7000 firmware. Below is a picture of a Honeywell L7000 on Firmware Version 9.00209..

If you find that your L5100 is running a firmware version of 5.05000 or higher (5.15000 or higher in Canada), then you will be limited to using the older L5100-WIFI with the MAC prefix of 00D02D. With any luck, you may be able to find a used model somewhere with the older prefix. But should your L5100 be running a lower firmware, then the system will be able to support any L5100-WIFI model, including the new ones that you can purchase from Alarm Grid. This is an excellent way to get an old L5100 System set up with low-cost IP monitoring.

Of course, if you have an L5200, L5210, or L7000, then it is recommended that you get the Honeywell LYNXTOUCH-MSD Firmware Updater Tool to upgrade the system firmware to the latest version. The latest firmware is 9.0213 at the time of this writing. Updating to the latest firmware version is always recommended. And as long as the firmware version is 8.00183 or higher, the system can support all versions of the L5100-WIFI, regardless of the MAC prefix.

If you have any questions about the L5100-WIFI or the Honeywell LYNX Touch Systems, then please reach out to us! We are best contacted via email at support@alarmgrid.com. Our hours for checking email run from 9am to 8pm ET M-F. This is also a great email to reach us if you are interested in starting new monitoring service. We look forward to hearing from you!

We have learned that the LYNX Connect App has been discontinued. The app can no longer be downloaded from the Apple App Store or the Google Play Store. Users wanting a second on-site option for controlling a LYNX Touch should use either a keypad or Total Connect 2.0, or upgrade to the Lyric.

The LYNX Connect App is a handy tool for many LYNX Touch users, It allows users to control a LYNX Touch System from a separate on-site device, all while enjoying the same user interface as the LYNX Touch System itself. The LYNX Touch Panel must have an L5100-WIFI Card installed and be on the same WIFI network as the device that is using the app to control the system. The app is designed for use with the L5100, L5200, L5210, and L7000 systems.

A very common application of the LYNX Connect App is to use it on a tablet that is mounted to the wall. By doing this, you can essentially have the tablet operate as a touchscreen keypad for the system. Many users find this to be a desirable option, as it is really the only way to obtain a secondary touchscreen controller for a LYNX Touch. By using a cheap tablet, you can readily establish a great secondary keypad for your system. Unfortunately, the discontinuation of the app means that this is no longer an option for many LYNX Touch users.

It turns out that all Firmware Versions 9 and higher for the LYNX Touch Systems does not work with the LYNX Connect App. In order to support the LTE communicators, a LYNX Touch System will need to be on some Firmware Revision that is higher than Firmware Version 9. The minimum Firmware Revision required depends on which LTE module you are using.

The LTE-L57A requires Firmware Revision 9.00.209 or higher, while the LTE-L57V requires Firmware Revision 9.00.201 or higher. Rather than update the app to make it compatible with the newer versions, Resideo made the decision to discontinue support. As a result, it is no longer possible to get the app for an Android or iOS device. Remember that the latest LYNX Touch Firmware Version is only available for the L5200, L5210 and L7000 Systems. If you have an L5100, then your system is running a lower Firmware Version, and it will still work with the app.

If you already have the LYNX Connect App downloaded, and your LYNX Touch System is running less than Firmware Version 9, then you can still continue to use the app. Many L5210 and L7000 users who use IP-only monitoring never upgraded to the latest Firmware Version. This is because the newer Firmware Versions only really benefit users with cellular connectivity. Just be aware that if you ever need to replace your Android or iOS device, you will not be able to re-download the app. And if you ever upgrade to Firmware Version 9 or higher on your panel, then the app will no longer work.

Remember that Firmware Version 9.00.201 or higher is needed to use the LTE-L57V, and Firmware Version 9.00209 or higher is needed to use an LTE-L57A. These updates are very important, as LTE is so crucial. If you want to replace a tablet that served as a secondary keypad using the LYNX Connect App, then you have a couple of options available. One possibility is to get a Honeywell 5828 or Honeywell 5828V Keypad. Both keypads will pair nicely with any LYNX Touch System.

You might also consider using Total Connect 2.0. This is an interactive monitoring platform that you can use to control your system from anywhere. TC2 is even more versatile and beneficial than the LYNX Connect App. This platform can be used to access the alarm system from virtually anywhere using the Total Connect 2.0 Mobile App. Since you can access it on a smartphone, many users find that it is even more convenient than setting up a second keypad.

Another option is to upgrade to the Resideo Lyric Alarm System. The Lyric has its own app called the MyHome Controller App that works in the same manner as the LYNX Connect App. The MyHome Controller app is still actively supported by Resideo, and it allows a tablet or smartphone to serve as a reliable secondary keypad. Other benefits for the Lyric include HomeKit compatibility, increased zone support, and its encrypted sensor options.

We apologize for any inconvenience that this may have caused. If you have any questions or concerns about the loss of the LYNX Connect App, or if you want to learn more about Total Connect 2.0, then we invite you to reach out to us. Our team is happy to help you determine the best replacement keypad option for your needs. The best way to contact us is by email at support@alarmgrid.com. You may also call us at (888) 818-7728 during our regular business hours of 9am to 8pm EST. We look forward to hearing from you!

UPDATE: The information presented below is outdated. The L5200 can now be updated using the LYNXTOUCH-MSD Firmware Updater Tool. Please read this blog for more information.

Alarm Grid has recently learned that the Honeywell 3GL, the longtime cellular communicator for the LYNX Touch Panels, has officially been discontinued. This leaves the Honeywell L5200 with no available cellular communicator. However, the newer LYNX Touch Systems still have cellular options.

The Honeywell 3GL was a cellular communicator that connected with the AT&T 3G Network. It was previously sold as the Honeywell 4GL. But Honeywell smartly changed the name, as it misled many people into believing it was a 4G communicator. The 3GL was compatible with the L5200, L5210 and L7000 Alarm Systems.

As for the L5210 and L7000, there are still cellular communicators available, specifically the LTE-L57A and LTE-L57V. Please note that the L5210 and L7000 must be running Firmware Version 9.00.209 or higher to support LTE-L57A, and Firmware Version 9.00.201 to support the LTE-L57V. More information on this is available here.

With the discontinuation of this module, the Honeywell L5200 now has no available cellular communicator option. Users of the L5200 who want to receive cellular monitoring should strongly consider upgrading to a newer system, such as a Honeywell Lyric Controller. This is Honeywell's newest wireless security system, and it has multiple cellular options available.

Please note that this news does not affect L5200 Systems that are already using an active 3GL Communicator. Any communicator that has already been activated will continue to function as normal. Additionally, if a user is able to find an existing 3GL or GSMVLP5-4G from somewhere else, then we can still activate it for cellular monitoring service with their L5200 System.

One alternative option for L5200 users without a cellular communicator is to go the WIFI-route instead. The system will support the L5100-WIFI module, which will allow the system to connect with a local WIFI network. Although WIFI is not as reliable as cellular service, it can be a good option if a user simply does not want to upgrade their panel. This is also a great option for Honeywell L5100 users, as that system also has no cellular radio in current production.

Finally, the ILP5 is still available for purchase, and it provides hardwired ethernet capabilities for any LYNX Touch Panel. But please note that a LYNX Touch cannot support both the ILP5 and a cellular communicator since they use the same port. Once a Honeywell LYNX Touch System is using IP or cellular communication, it will be capable of being used with the Total Connect 2.0 service.

The following table outlines all of the communicators available for the Honeywell LYNX Touch Systems and their compatibilities with each of these panels:

If you have any question about this news, please do not hesitate to reach out to us for further assistance. You may email us at support@alarmgrid.com, or you may call us at 888-818-7728 from 9am to 8pm EST M-F. We look forward to hearing from you.

Alarm Grid is sad to announce that the Honeywell GSMVLP5-4G Cellular Communicator for Honeywell LYNX Touch Systems has officially been discontinued. Without this cellular communicator, a Honeywell L5100 System will have no way of using cellular communication for alarm monitoring.

The Honeywell GSMVLP5-4G was the first 4G cellular communicator ever released for Honeywell Alarm Systems. It was designed exclusively for use with Honeywell LYNX Touch Panels. Now that the module is discontinued, it becomes much more difficult for an L5100 user to upgrade their system to cellular.

Please note that existing GSMVLP5-4G modules are not affected by this news. If you already have an L5100 or any other LYNX Touch System that uses a GSMVLP5-4G for monitoring, then the module will continue to work just fine. Likewise, if you have a LYNX Touch L5200, L5210 or L7000, you can still upgrade to cellular using a Honeywell LTE-L57V or 3GL. Please note that the L5200, L5210 or L7000 System will need to be running Firmware Version 9.00.201 or higher to support the LTE-L57V module. For more information on the LTE communicator, please review this prior blog post.

Unfortunately, the L5100 System needs the GSMVLP5-4G to use cellular communication. If a user can obtain a second-hand GSMVLP5-4G module, they will still be able to activate it and use it with the system. Additionally, an L5100 user can forgo cellular and use an L5100-WIFI to access Total Connect 2.0. But please note that this will not be as reliable as using cellular communication.

Perhaps the best option for an L5100 without an active cellular communicator is to replace the system entirely with a newer model. We recommend purchasing the Honeywell Lyric Controller as a replacement. All of the sensors used with an L5100 will work with the Lyric. The Lyric is also compatible with Apple HomeKit, making it great for users looking to get started with smart home automation and the ability to control Z-Wave devices using voice commands. A LYRICLTE-A can be added to get the system connected to a cellular network. Update: The LYRICLTE-V is also available!

With heavy hearts, we are sorry to announce that the Total Connect 2.0 service, powered by Honeywell, no longer supports the slide show feature.

While most Total Connect 2.0 users probably never even knew this feature existed, it was a pretty cool option for turning a LYNX Touch security system (models L5100, L5200, L5210 and L7000) into a digital picture frame.

From the TC2 Locations module, you could edit the house icon and click on the 'Edit Slide Show' button to upload images to your account from your computer. Honeywell's servers then download to the LYNX Touch system associated with that TC2 account/location (as long as the system had an ILP5 or L5100-WIFI internet communicator installed and online). Once the images were downloaded to the system, you could use the master programming mode (Security > More > Tools > enter Master Code) to go to the Slide Show option and setup your images to display on the panel's touchscreen when the system was sitting idle.

Honeywell indicated that the feature was removed due to "cyber security concerns" and while you can no longer use your LYNX Touch system as a digital picture frame, the new Lyric Controller does still offer the Slide Show feature. You just have to use a USB stick to load the images to the Lyric locally as the feature has been removed from Total Connect 2.0 on all systems. We have an FAQ on how to use the slide show feature on a Lyric system online at https://www.alarmgrid.com/faq/how-does-slide-show-... and if you have a LYNX Touch system now that was using this feature and want to discuss upgrading to a Lyric, we'd be happy to help. You can email us at support@alarmgrid.com or call us M-F 9-9 EST at 888-818-7728.

AT&T has been announcing a deprecation of the 2G radios for a number of years. At midnight January 1, 2017, the network was turned off.

If you're one of the many Americans who has a 2G alarm system, and you've been caught flatfooted for one reason or another, Alarm Grid is here to help. For those who upgrade their 2G radio programmed to a different company's service to a new radio, Alarm Grid will provide 2 months of free monitoring.

If you have a bf error showing on your panel or a Check 103 error, we have some great FAQs explaining what you need to do to fix the error. Additionally, below, you will find a guide explaining how to go about fixing the problems. Generally you will need to replace your radio - a move that is dependent on the type of system you have. The following alert is on our FAQs pertaining to this issue, and will walk you through what you need to do to upgrade.

We will be serving you diligently during the next two days (May 28 and 29). But we're admittedly not going to be running at full capacity. We will be running at half capacity all day. So we're asking all of our amazing customers to have some patience. The techs you have come to know and love are doing training during this time so that we can bring you even better, faster service.

Before you call, we would love if you considered first sending an email to support@alarmgrid.com. We can answer emails more quickly than we can get back to phone calls, especially considering that many of the Alarm Grid techs will be able to check mail during training. If you do call, and no one takes your call, please leave us a message. Rest assured that we will get you in the queue and call you back in the order you called us. Also, we're going to do our best to have the on-site chat channels manned all day. Feel free to use that.

We are going to add 2Gig's GoControl security system and peripheral products over the course of the next few weeks. This expansion from Honeywell-only, will give our customers choice with one of the most recognized (though new) brands in the security space. Like Honeywell's Total Connect, 2Gig is generally intended for use with alarm.com. While we absolutely love the incredible features of Total Connect, Alarm.com is another gerat platform that we are proud to begin offering sometime in the next couple months. Again, for you, that means you will have the choice between two of the best security products in the space.

For 2Gig fans out there who have been anticipating our foray into the much loved brand, we promise that we will be giving it the same sort of love we have given all our previous security systems. FAQs, documents, compatibility pages, videos and more are coming! If you have been waiting for Alarm.com + Alarm Grid, you won't have to wait much longer!

The L5100 is the security system that changed the industry forever. Honeywell gave things a try with its predecessor, the L5000, but it just wasn't right. While the L5000 may not have hit on all cylinders, the L5100 was a smashing success. A Z-Wave controller, a security system, and a beautiful, simple to use user interface ushered in a new era of home security. Responsive, colorful, and simple to use, the L5100 made home security accessible to the common man. The result of the simple 3-touch auto-enrolling process for zone programming, or simple typing in of a serial number, made it so there were no longer complicated button presses to get in and out of programming.

Moreover, this wireless panel was the first full-scale wireless panel that truly won over the old-timers who resisted the transition from wired to wireless. The modular approach to adding communicators gave consumers choices about what exactly they want their system to do.

As of today, stock across the country has been exhausted of this groundbreaking panel, and we have discontinued its sale in our store. It has been replaced by Honeywell's newer, bigger, better panels the L5200 and the L7000. These two new panels are wonderful replacements for this workhorse, and we're sure they are going to become the industry standard for years to come. While different in some ways, the L5200 and L7000 are wonderful additions to the Honeywell family and welcome replacements for what was once a revolutionary panel.
