THE FIRE SENTRY SMOKE ALARM
The Smoke Alarm is operational once the battery is connected. When
products of combustion are sensed, the unit sounds a loud pulsating alarm
until the air is cleared.
False Alarms ‘Hush’ Control
Units with the ‘hush’ feature have the capability of temporarily disabling
the alarm circuit for approximately 7 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 is deactivated by pushing the “Alarm
Hush” button on the Smoke Alarm cover. The alarm will silence
immediately and ‘chirp’ every 30-40 seconds for approximately 7 minutes
to indicate the alarm is in the temporary ‘hush’ condition.
The smoke alarm will automatically re-activate after approximately 7
minutes and sound the alarm if particles of combustion are still present.
The ‘hush’ feature may be used repeatedly until the air has cleared.
Dense Smoke will override ‘HUSH’ control feature and sound continuous
alarm.
Warning: Before using the alarm ‘HUSH’ feature, identify the source of
smoke and be certain that safe conditions exist.
Testing
Test by pushing test button on cover and holding button down for 2
seconds minimum. This will sound alarm if all electronic circuitry, horn
and battery are working. If no alarm sounds, the unit has a defective
battery or other failure. You can also test alarm by blowing smoke into it.
Test alarm weekly to assure proper operation. Erratic noise or low sound
from alarm may indicate a defective alarm. Return it for service.
Warning : Test smoke alarm operation after caravan has been in storage,
before each trip and at least once per week during use.
