Please Note: The DSC LE4000 universal cellular AT&T LTE alarm communicator has been discontinued and replaced by the LE4000E-AT model number.

DSC LE4000 Product Description:


The DSC LE4000 is a universal wireless cellular AT&T LTE alarm communicator that is compatible with control panels that communicate using the Contact ID and SIA formats. The LE4000 connects the alarm control panel to the cellular network and reports alarm signals directly to the GeoArm monitoring station receiver (Sur-Gard System I-IP/II/III/IV/5). The LE4000 uses the cellular network to ensure low-cost, high-speed and reliable alarm communications.

The LE4000 is installed between the telephone connection of a control panel and telephone line. When used in a backup role, the communicator assesses the connection to the PSTN phone line, and if that has failed, it then connects to the cellular network to send an alarm signal to the GeoArm central monitoring station. In a primary role, the communicator simply sends the alarm transmission over the cellular network immediately. Alarm signals are transmitted directly to the IP linecard of the GeoArm monitoring station receiver without the need of clearinghouse involvement saving valuable time and eliminating a potential point of failure.

Activating and initializing the LE4000 can be done using the mobile interface or web-user interface provided by C24 Communications. No special tools are required. The LE4000 can be configured to conveniently accept SMS commands from select phone numbers to trigger remote activation of the PGM outputs. Outputs can be used to remotely arm/disarm your alarm system or trigger other actions such as opening a garage door.

The LE4000 can intelligently monitor the panel transmission and switch over to the cellular network when the phone line is down. This function will occur for both traditional POTS and newer digital technologies (i.e. VoIP).
