Alarm.com Universal Communicator (AUC) – LTE Alarm Panel Communicator
 
Description
The Alarm.com Universal Communicator (AUC) is a versatile LTE communicator designed to bring Alarm.com connectivity to a wide range of existing security systems. Ideal for retrofits, the AUC captures Contact ID and SIA signals transmitted over a traditional phone line and securely delivers alarm events to Alarm.com over the cellular network.
