Interlogix 600-1048-XT-ZX-VZ

The Interlogix 600-1048-XT-ZX-VZ cellular communicator connects with the Verizon CDMA network. Verizon's CDMA network is essentially a 3G version of the AT&T network. This network will soon be discontinued in favor of the faster Verizon LTE network. Alarm.com has already announced that they will stop allowing new CDMA activations in June 2018. CDMA radios that are activated before June will remain signaling until the Verizon CDMA Network is shutdown. Then, the official CDMA sunset will render this communicator useless. For faster speeds and a longer product life, we recommend choosing one of these LTE communicators from Verizon, AT&T or Telus (Canada Only) networks.

The Interlogix 600-1048-XT-ZX-VZ is a Verizon (CDMA network) Cellular Communicator for Interlogix Simon XT V1.3 or higher, XTi and XTi-5 alarm systems. These are all-in-one (AIO) alarm systems where the control panel is integrated into the keypad. This Verizon radio sits inside the keypad on the board, and it allows the panel to communicate with Alarm.com. This is a third-party service that requires a monthly subscription with a dealer. You can choose to enroll in central station monitoring or self-monitoring using the Alarm.com app. The app offers remote interactive access and customizable alerts via email and text notifications on your mobile device. Generally, the Alarm.com dealer will bundle the cellular data charges into your monthly rate for monitoring service. Make sure to clarify this before activation.

Cellular communicators are always a preferred method when it comes to reliable alarm monitoring. Phone lines and internet modules rely on physical wiring that can be cut or lose contact over time. Phone lines will never support the newer interactive technologies offered by services like Alarm.com because of their limited infrastructure. Internet modules can be convenient, but they rely too heavily on a functioning local equipment like a router and a simple IP conflict can kill your monitoring connection. IP setups are great in terms of speed but not the best when it comes to reliability.

The installation guide for the module walks you through how to power down the panel and physically install the cell card. There are two plastic tabs that hold the card into place. After installing the module, you will want to setup an activation appointment with an Alarm.com dealer. During the activation you will need to perform a "GSM phone test." This will generate an activation signal to the server and register the radio automatically.

**Please note: any cellular communicator automatically is programmed to Zone 40 on your panel. If you already have a sensor configured to that zone, remember to reprogram it.** Also, Simon XT panels must be firmware version 1.3 or higher to support this radio.
