Smoke Detector with  (490-0466)       Operation        Faxback Doc. # 15979
Silence Control

The smoke detector is operating once the battery is connected.  When
products of combustion are sensed, the unit sounds a loud alarm which
continues until the air is cleared.

FALSE ALARMS "SILENCE" CONTROL

The silence feature reduces the sensitivity of the alarm circuit for
approximately 8 minutes.  This feature is to be used only when a known
alarm condition, such as smoke from cooking, activates the smoke alarm. 
When the silence feature is needed, under smoking conditions; the smoke
alarm sound is deactivated by pushing the test button on the smoke alarm
cover for at least 5 seconds and then releasing.  The detector will
automatically reduce sensitivity and "beep: every 30 to 40 seconds for
approximately 8 minutes to indicate the alarm is in the temporary silent
condition.  the smoke alarm will gradually reactivate during the 8 minutes
and sound the alarm if particles of combustion are still present.  The
silence feature may be used repeatedly until the air is cleared.

CAUTION:  Before using the alarm silence feature, identify the source of
          smoke and be certain that safe conditions exist.

TESTING

Test by pushing the test button on the smoke alarm cover for at least two
seconds, until the alarm sounds, then release immediately.  The alarm
sounds 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 the alarm by blowing smoke into it.  Test the alarm weekly to
assure proper operation.

NOTE:  The silence mode might be activated by accident during normal
       testing if you do not release the test button immediately after the
       alarm sounds.  The smoke detector will not reponse to the test
       button when the unit is in an alarm silence condition, which will be
       noted by an audible "beep" every 30 to 40 seconds.
