Supervised Smoke Detector
The AT&T Supervised Smoke Detector is a photoelectric type, designed to
detect a fire in its early stages so that you can escape from your house
before smoke reaches a dangerous concentration level. When the detector
senses smoke particles, it simultaneously sounds an alarm (using a built-in
siren) and sends an alarm to the Central Controller.
During normal operation, the On/Alarm light in the center of the smoke
detector flashes once every 7 seconds. During an alarm, it
remains lighted.
Pressing and holding
Test for approximately 20 seconds checks the
operation of the smoke detector.
NOTE: When the smoke detector batteries are low, a built-in horn beeps
once every 7 seconds. If the batteries are not replaced, the smoke
detector will send a message to the Central Controller. See 30 for
instructions on battery replacement.
