Dsc ADC-SEM300PS-VZ Lte Sem Cellular Alarm Communicator

Product Description

The DSC ADC-SEM300PS-VZ is an LTE cellular alarm communicator designed to transmit alarm signals over the Verizon LTE network. It connects a security control panel to a central monitoring station or Alarm.com platform without relying on a traditional phone line or broadband connection. This unit serves as a primary or backup communication path for residential and light commercial intrusion alarm systems. Licensed alarm technicians and security integrators are the typical installers. The LTE connection provides a dedicated, standalone communication channel that operates independently of the customer's internet or telephone service.

The ADC-SEM300PS-VZ is intended for use with compatible DSC security control panels in residential and light commercial applications. It is suited for sites where traditional landline or broadband-based communication is unreliable or unavailable. The unit integrates with the Alarm.com ecosystem, enabling remote system management, event notifications, and monitoring services when paired with an active Alarm.com service plan through a licensed dealer.

Installation Notes

Installation should be performed by a licensed alarm technician familiar with DSC control panel wiring and Alarm.com activation procedures.

Alarm.com activation requires coordination with an authorized dealer and an active service plan before the unit will communicate with the monitoring platform.
