OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the battery power is connected and turned on.
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 appox. every 40-45 seconds to indicate
the alarm is properly functioning.
LOCAL ORIGINATING 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 ® Alarm Origination Feature allows the user to identify
the initiating alarm smoke alarms in an interconnected alarm system. If an interconnected alarm
system is initiated by one of the alarms, when the alarm system exits alarm condition, the user can
identify the initiating alarm by:
a. Pressing and releasing the test button on any alarm in the system.
b. Interconnected alarms will sound and then stop.
c. The originating smoke alarm will continue to sound 60 seconds to allow ample time to quickly
find originating alarm.
RESET: To reset the QUICK FIND ® Alarm Origination Mode - Hold the Test/Silence button for
10 seconds, or temporarily remove (and then replace) the battery. This will clear alarm
origination indicator.
