OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the battery power is connected by removing the
PULL-TAB. When products of combustion are sensed, the alarm sounds a loud alarm which continues
until the air is cleared.
This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the
horn produces three beeps followed by a two second pause and then continually repeats.
READY/ACTIVE CONDITION: The red LED blinks on once approx. every 40-45 seconds to indicate
the alarm is properly functioning.
ALARM CONDITION: The red LED blinks on once approx. every 2 seconds and the alarm emits a
loud, pulsating alarm sound.
NUISANCE ALARMS: The smoke alarm is designed to minimize nuisance alarms. Smoking will
not normally set off the alarm unless smoke is blown directly into the smoke alarm. Combustion
particles from cooking may set off the alarm if the smoke alarm is located close to the kitchen
cooking surface. Large quantities of combustion particles are generated from spills or broiling.
If the smoke alarm does sound, check for fires first. If a fire is discovered, get out and call the fire
department. If no fire is present, check to see if one of the reasons listed above may have caused
the alarm. Use the Silence Feature if it is a nuisance alarm, or reset the alarm by pressing and
holding the test button for ten seconds. Refer to RESET below.
TESTING: Test by pushing the Test button on the smoke alarm cover until the alarm sounds, then
release. The alarm sounds if all electronic circuitry, horn and battery are working. If no alarm sounds,
the alarm may have a power supply failure. Test the smoke alarm weekly to assure proper
operation.
ALARM ORIGINATION: The QUICK FIND ® feature will allow you to immediately locate the originating
alarm (once the alarm has stopped sounding). To initiate QUICK FIND ® , press the Test/Silence
button on each alarm. After releasing the button, the originating alarm will continue to sound for 60
seconds. In a non-interconnected installation, it is necessary to test each alarm to determine the
originating alarm.
RESET: To reset the QUICK FIND ® Alarm Origination condition, press and hold the Test button
on any alarm for at least 10 seconds and then release. Reset after each alarm. The reset
feature will reset all interconnected units.
END-OF-SERVICE LIFE NOTIFICATION: A majority of home fire deaths are a result of no smoke
alarms or no working smoke alarms. In addition to the "replace by date" stamped on the back of your
alarm, your alarm contains a unique audible end-of-service life notification feature. When it is time
to replace your alarm, which is after approximately 10 years of operation from initial power up, the
alarm will sound 1 beep approx. every 60 seconds and the red LED will blink on once approx. every
40-45 seconds. The alarm should be replaced immediately.
The end-of-service life signal can be silenced for approximately 6 hours. To perform this function,
press and release the test button. The alarm will sound for approximately 60 seconds while it resets.
After the reset function is completed, the alarm will be silent for approximately 6 hours. The end-of-
service life signal will activate after the silence period.
