Alarm Grid Communicator Replacement

By

When you move into a new home or office, you may find an existing security system that you're hoping to put to use. Or maybe you have an already monitored alarm panel, and you want to extend its useful lifespan. Alarm Grid is here to help determine the best course of action for your needs.

Most users with a security system will want to have it monitored. When we refer to alarm monitoring, we are talking about the ability of the system to send out signals in the event of an emergency, such as a break-in or fire. This allows the user to receive automatic dispatch from a trained operator at a central monitoring station. It also makes it possible for the end user to receive text and/or email alerts that notify them of the situation so they can contact help themselves. Whether you go with central station monitoring or self-monitoring is a personal decision. You can learn more about Alarm Grid monitoring plans on this page.

For alarm monitoring to work, you need a security system with a communicator that is installed and activated. If you inherit an old or existing system, then there is a good chance that you can get it monitored by simply replacing its communicator. This isn't always possible, but it can save you money by not having to start from scratch with a brand-new system. And for optimal reliability, we recommend getting the system set up with a cellular communicator, specifically an LTE cellular communicator. This will require a cellular monitoring plan, but it is the best way to ensure that your system stays reliably monitored.

Always power down your panel completely before installing a cellular communicator!

There are many advantages to cellular monitoring. For one, cellular outages are almost unheard of when an adequate cellular signal is obtained. The same cannot be said for internet, as internet outages are relatively common. A power outage won't affect your system's cellular connection, as the communicator will stay running using the panel's backup battery. And since cellular is completely wireless, there's no line for an intruder to "cut" to try and disrupt your system's cellular connection. This is far and away the most consistent and reliable type of communication available for an alarm system.

We also want to stress the importance of getting an LTE cellular communicator. Older cellular networks like AT&T 3G and Verizon CDMA are in the process of being shut down. Cellular communicators that connect with these older networks can no longer be activated. But LTE, which stands for Long-Term Evolution, provides a way to "future-proof" your system so that it can stay monitored for many, many years. Most systems capable of being set up for monitoring service will have some type of LTE option available. Many users with existing systems that are already monitored are simply looking for ways to upgrade their systems to LTE so that they remain connected as older cellular networks are shut down. If you would like to learn more about the 3G/CDMA sunset, we encourage you to check out this post.

Today, we're going to take a look at many of the popular alarm systems and explain which communicators you can use to get them set up with LTE. Just be aware that many panels will require you to know the system's Installer Code (IC) so that you can enter programming. This is an important step for setting up your system and getting it monitored. Simply find your panel in the table below, and review the relevant information.

Keep in mind that only communicators currently sold by Alarm Grid are listed. There may be other, discontinued alarm systems that we don't mention. And if you're having trouble identifying your panel, you can always reach out to us by emailing support@alarmgrid.com for assistance.

Note: In the chart below, IC is used to indicate the Installer Code:

My panel isn't listed!

If your panel isn't listed in the table above, then all hope isn't lost quite yet. Nearly any hardwired alarm panel with a phone dialer can use a device called a Telguard TG-1 Express to connect with an LTE cellular network. The TG-1 Express will take over your system's dialer and convert the phone line signal into a cellular signal. This is a great option that works in many situations. Just be aware that you may still need to be able to access system programming using the Installer Code to configure some settings. This can be easier said than done, and many users simply elect to upgrade to a newer wireless panel. But if you are familiar and experienced with the panel you are using and you can handle the programming, then you can leave the monitoring to us. The Telguard TG-1 Express is available in an AT&T LTE model and a Verizon LTE model.
