7. Operation and Testing
OPERATION: The alarm is operating once it is activated and testing is
complete. When products of combustion, (smoke), are sensed, the unit
sounds a loud 85dB pulsating alarm with voice message. The voice message
for smoke detection is “Fire! Feu!”. The strobe will flash every second. This
will continue until the air is cleared.
WARNING: Due to the loudness (85 decibels) of the alarm,
always stand an arm’s length (about 2.5 feet) away from the
unit or use ear protection when testing, and avoid looking at the
bright strobe directly, or cover it with your hand.
Strobe Synchronization
This strobe alarm will automatically synchronize (flash at the same time)
with other P4010ACLEDSCA strobes that are part of the interconnected
system. Synchronization will take up to 20 seconds when in alarm.
Note: The alarms will not synchronize during test mode.
TESTING: Test your alarm by pressing the test button until the unit chirps,
then release the test button. The unit will then emit three long alarm
beeps, followed by the voice message “Fire! Feu!” and a series of strobe
flashes. Alarm, voice, and strobe will activate if the electronic circuitry,
horn, speaker, and battery are working. If the alarm, voice, or strobe do
not activate, the unit must be replaced.
Weekly testing is required to ensure proper operation. Erratic
or low volume sound (or no sound), or no strobe activation from your
alarm may indicate a defective alarm and it should be returned for
service. See deactivation section to determine how to prepare the unit
for shipment or disposal.
WARNING: DO NOT use an open flame to test your alarm,
you could damage the alarm or ignite combustible materials and
start a structure fire.
Ambient Light Sensing
During low light ambient conditions, the green LED will reduce in
brightness and intensity. The unit samples the ambient light conditions of
the alarm’s location and, if possible, determines a Night / Day cycle. A valid
Night / Day cycle will inhibit Low Battery chirps at night. It will also inhibit
End of Unit Life chirps at night if the unit is within the first 30 days of the
End of Unit Life period. After 30 days, the chirps will not be inhibited.
WARNING - REPLACE ALARM AS SOON AS POSSIBLE WHEN IN
END OF UNIT LIFE OR LOW BATTERY MODE.
If the unit cannot determine a valid Night / Day cycle because the unit is
located in either a constantly dark or lighted location, Low Battery and End
of Unit Life chirps will not be inhibited. If the unit is moved to a location
that is not constantly dark or lighted, it will determine a Night / Day cycle
because the unit continuously samples ambient light conditions.
