BR 8221 Operating Instructions
6. The smoke detector is activated and the red
LED will light up for about 2 seconds
Mute Function
If the smoke detector triggers a false alarm esp.
due to cooking vapours, dirt or the like, the alarm
can be muted or shut off using the test button on
the smoke detector. After pressing the test button
(about 1 second), two peeps will sound and the red
LED will flash every 3 seconds to indicate that the
smoke detector has been muted. The sensitivity is
minimised to the extent that it will no longer
sound false alarms. Its functional readiness
however is retained so that the smoke detector
will sound alarm as soon as the concentration of
smoke increases heavily again. This reduction in
the sensitivity of the smoke chamber is automati-
cally reversed again after 10 minutes. The smoke
detector will return to its normal sensitivity.
Note:
If you want to reverse the mute mode before it
automatically re-sets, then press and hold the test
button for about 1 second. The smoke detector will
emit 3 short peeps and will be active again.
