7.
Turn on AC power and check the LED's for proper operation. The green LED lights to indicate
AC power. The red LED will flash every 40-60 seconds to indicate proper operation.
OPERATION, TESTING & MAINTENANCE
OPERATION:
The smoke alarm is operating once the power is connected and turned on (the battery
must also be installed). When products of combustion are sensed, the unit sounds a loud alarm
which continues until the air is cleared.
This alarm incorporates the internationally recognized horn signal for evacuation. During alarm
mode, the horn produces three short beeps followed by a two second pause and then repeats.
STANDBY CONDITION:
The red LED flashes once every 40-60 seconds to indicate the unit is
properly functioning.
LOCAL ALARM CONDITION:
The red LED flashes rapidly and the unit emits a loud, pulsating
alarm sound.
REMOTE ALARM CONDITION:
The red LED is off and the unit emits a loud, pulsating alarm.
GREEN LED:
The green LED is on whenever AC power is turned on.
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. The alarm may
continue to sound for up to 10 seconds after the button is released. If no alarm sounds, the unit may
have a defective battery or other failure.
Test the smoke alarm weekly to assure proper operation.
If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one
that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as
directed. Use of non-UL Listed products or improper use of UL Listed products may affect
the smoke alarm's sensitivity.
FALSE ALARMS "SILENCE" CONTROL:
Units with the "silence" feature have the capability of
temporarily reducing the sensitivity of the alarm circuit for approximately 3-9 minutes. This feature is
to be used only when a known alarm condition such as smoke from cooking activates the smoke
alarm. The smoke alarm "silence" feature is activated by pushing the Hold to Silence button on the
smoke alarm cover for at least three seconds. The smoke alarm will automatically reduce sensitivity
and the red LED will light for approximately 3-9 minutes to indicate the alarm is in the temporary
silent condition. The smoke alarm will gradually regain normal sensitivity and sound the alarm if
particles of combustion are still present. The "silence" feature may be used repeatedly until the air
has cleared.
