WARNING:
The DLS supports Fire Alarm Verification for use with smoke detectors which
can be utilized to delay the transmission of a smoke alarm to the AT&T Digital Life Central
Monitoring Center. When smoke is detected, the alarm sounds a loud temporal 3 local
alarm. Twenty (20) seconds after the local alarm sounds, the built-in transmitter sends a
digitally coded wireless signal to the DLC. The wireless signal will be repeated every 20
seconds as long as smoke is still present. In order to reduce the likelihood of reporting false
smoke alarms, the Fire Alarm Verification feature can be used. If the Fire Alarm Verification
feature is enabled, the DLC waits for two smoke detector signals within 25 seconds before
a smoke alarm is reported to the AT&T Digital Life Central Monitoring Center.
In addition to the photoelectric detector, the unit contains an integrated fixed 135°
temperature and rate-of-rise heat sensor that will send an alarm signal based on
temperature detected.
