Dsc LE4000E-AT Lte Alarm Communicator

Product Description

The DSC LE4000E-AT is an LTE cellular alarm communicator designed to transmit alarm signals from a security control panel to a central monitoring station over an AT and T LTE network. It replaces or supplements traditional phone-line or broadband communication paths, giving security installers a reliable cellular uplink where landline infrastructure is unavailable or unreliable. The communicator integrates directly with compatible DSC control panels and is sold as a single unit. Licensed alarm technicians and security system integrators are the primary installers of this device.

This communicator is suited for residential and light commercial security installations where a dedicated cellular path is required for UL-listed or dealer-monitored alarm reporting. It is typically installed inside the control panel enclosure and connected to the panel's communication bus or telephone terminals. Sites that have eliminated traditional POTS lines or require redundant communication paths are common deployment scenarios for this type of cellular uplink device.
