Description

The Interlogix 600-1048-XT-ZX-AT is an Alarm.com cellular communicator that uses the AT&T 3G network. Alarm.com has already announced that it will phase out the 3G network in favor of the superior LTE network. This will be long term process, but as they did with the CDMA (Verizon's 3G equivalent), they will most likely stop the ability to activate new 3G radios several years before the actual 3G sunset.

With that said, Alarm Grid highly recommends planning ahead and future proofing your alarm system with an LTE communicator. For faster speeds and a longer life expectancy, we recommend choosing between the AT&T and Verizon LTE communicators for the Simon series.

The Interlogix 600-1048-XT-ZX-AT is an AT&T 3G cellular communicator built for the Interlogix Simon XT V1.3+, XTi and XTi-5 alarm systems. By adding this module to your compatible Simon control panel, your alarm system will transmit and receive wireless signals from the Alarm.com. This is a server that hosts cellular-based monitoring services. Alarm.com offers interactive services in the form of an app, which allows you to remotely access your system and forward signals to a central station for emergency dispatching. If you elect to enroll in Alarm.com service, this 3G radio allows you to disconnect your old phone line (POTS) and either upgrade to a VOIP service or drop the phone service altogether. Cellular communications are the most reliable way to monitor your alarm system for several reasons.

Unlike a traditional phone line, cellular modules do not require any physical wiring. This prevents any issues with line cuts locally in the home/business or on the street where the line is coming in. Internet modules have also become more prevalent lately. However these modules rely on AC power to your router and modem; as well as proper router functioning as far as IP addressing from the DHCP server. All in all, the cellular comm path is by far the most stable.

Keep in mind that you will need to enroll in service with an Alarm.com dealer in advance. Generally, the cellular data fees from AT&T are included in the monthly monitoring costs. Confirm this with your dealer. Before adding this module to your Interlogix Simon Panel, power down by removing AC power and your backup battery. The cell card sits into the corner of the inside of your self-contained panel. There are two plastic tabs where the module should sit under (see photo in the install guide). Insert the included antenna through the channel in the back plate and feed it into the wall cavity behind the alarm panel. After the module is installed, you can restore power to the panel.

In order to register the communicator with Alarm.com you need to perform a "GSM phone test." This will automatically generate a signal to the prebuilt account on Alarm.com and register the radio. From there you can execute system system test to ensure the system is properly reporting alarm signals to the app and the Central Station.

On the Simon XT: Select “System Tests” in the main menu and Press “OK." Then enter the installer code (default 4321) and select "Comm Test". This will initiate the GSM phone test where the panel will acquire a cellular signal.

On the Simon XTi and Simon XTi-5: Select the gear icon on the bottom right of the home screen. Press "Programming" and enter your installer code (default 4321). Select "System Tests" followed by "Comm Test".

Please note: Any cellular communicator automatically is mapped to Zone 40 on your panel. If you already had a sensor configured to that zone, you will need to reprogram it to a different zone. Also, Simon XT panels must be firmware version 1.3 or higher to support this radio.

Get an LTE Communicator Instead.

We do not recommend the Interlogix 600-1048-XT-ZX-AT. This 3G communicator can no longer be activated with the Alarm.com 3G sunset. If you need an AT&T communicator for your Interlogix Simon Panel, you should purchase the Interlogix 600-1048-XT-LTE-AT. There's also a dual-path communicator available called the Alarm.com XT-511-US-AT that uses AT&T LTE and IP connectivity. Either of these communicators is a much better option than the Interlogix 600-1048-XT-ZX-AT.

Cellular service providers like AT&T are currently shutting down their older 3G networks in favor of the more advanced LTE networks. The LTE networks are faster and more reliable, which makes them better-suited for alarm monitoring. Since 3G networks will be shut down in the coming years, companies that operate interactive alarm monitoring platforms no longer allow 3G activations. As a result, you can no longer activate an Interlogix 600-1048-XT-ZX-AT for use with Alarm.com. If you have already activated this module, then you can continue to use it until AT&T shuts down their 3G network. This is expected to occur by the end of 2022. We recommend upgrading to an LTE communicator before then so that you do not experience any interruptions to your monitoring service.

Customers looking to get an AT&T LTE communicator for an Interlogix Simon XT, Simon XTi, Simon XTi-5, or a Simon XTi-5i should get an Interlogix 600-1048-XT-LTE-AT instead. This communicator is available from Alarm Grid for $166.99 at the time of this writing. If you don't mind spending a bit more, you can get the Alarm.com XT-511-US-AT, which costs $197.99 at the time of this writing. Both the Interlogix 600-1048-XT-LTE-AT and the Alarm.com XT-511-US-AT also provide Z-Wave functionality. This means that you can start building a Z-Wave network for use with Alarm.com. Remember, you will need an alarm monitoring plan that includes cellular communication to activate one of these modules and use it for monitoring service.
