Condition: AC Power is not present and alarm is receiving DC Power.
Recommendation: Check the breaker or fuse box for power. If
the breaker or fuse box looks normal, call a licensed electrician
for assistance.
Condition: One or more alarms not responding to interconnected alarm.
Recommendation: Press and hold the smoke alarm Test/
Silence button for at least 5 seconds. If still no alarm, turn off
AC Power at the circuit breaker or fuse box and disconnect the
alarm from the mounting bracket and make sure the connector
plug is securely attached on units that did not alarm. If still no

wire is connected to the neutral wire.

if an alarm sounds by calling an Emergency Service and getting out
of the home.

interconnected smoke alarm has sensed smoke, causing all
interconnected units to alarm.
Recommendation: If hazard is identified, please take all precautions
if an alarm sounds by calling an Emergency Service and getting out
of the home.
Condition: Nuisance Alarm.
Recommendation: If there is no hazard present, verify the alarm is
mounted in the correct location (see User's Manual, "AVOID THESE
LOCATIONS" section). Reset alarm as instructed below.
Condition: Alarm has sensed smoke.
Recommendation: Silence Feature is activated by pressing and
releasing the Test/Silence button on the initiating alarm while in alarm
condition. Silence mode will last for approx 8-12 minutes with the red
LED blinking once approx. every 10 seconds.
Condition: One alarm has sensed smoke.
Recommendation: QUICK FIND
system, it is difficult to determine which alarm initiated the alarms to sound.
The QUICK FIND ® feature will immediately allow you to locate the
originating alarm (once the alarms have stopped sounding). To initiate
QUICK FIND ® , press the Test/Silence button on any alarm. After releasing
the button, the test sequence will sound and then stop. Then, the originating
alarm will continue to sound for approx 50 seconds. In a non-interconnected
installation, it is necessary to test each alarm to determine the originating
alarm. Reset the originating alarm.
Condition: Alarm needs to be reset due to varying conditions/
previous alarms.
Recommendation: To Reset the Alarm, hold the Test/Silence button
for approx 10 seconds. This will clear alarm origination. Reset after
each smoke alarm event.
Condition: Low Battery
Recommendation: Check to make sure the battery activation pull
tab has been completely removed, battery polarity is correct and the
battery terminals are making contact with the smoke alarm contacts
in the battery drawer. If chirp continues, replace the 9V battery (see
User's Manual for recommended battery types).
Condition: Product End-of-Service Life signal.
Recommendation: Replace alarm immediately. To silence signal for
approx. 9 hours, press and release the test button. The alarm will
sound for approx. 60 seconds while it resets. After the reset function
is completed, the product end-of-service signal will be silent for approx.
9 hours and will reactivate after the silence period.
