About Your AT&T Digital Life System
Your professionally installed AT&T Digital Life System (DLS) features a Digital Life Controller (DLC-100), which is typically installed in a closet, utility roroomor basement.
The DLC-100 is a wireless controller that monitors a wide range of devices for the detection of fire (smoke detectors and CO detectors) and intrusion (door/window sensors, motion sensors, and glass breakage sensors) alarms. Once the DLC-100 is installed and activated, it constantly monitors smoke detectors and CO detectors and automatically reports alarms to the AT&T Digital Life Central Monitoring Centers. When the system is armed, the DLC-100 automatically reports intrusion alarms to the AT&T Digital Life Central Monitoring Centers.
