Operating Instructions BR 1211
During this delay, the detectors linked with
detectors that have already sounded their alarm
give alarm through a blinking optical display 1 x
about every 2 seconds and by emitting a loud
peeping sound about every 6 seconds.
Alarm Memory Function
If a detector signals and alarm due to smoke or a
disruption (but not from pressing the test button),
then the alarm incident is recorded and stored in
this detector for up to 12 hours. The stored alarm
will be indicated every 8 seconds by a simultane-
ous blinking and peeping sound. The detector's
regular function is not impeded during this time.
The memory can be erased by pressing the test
button until you hear an alarm signal.
Operational Lifespan of Battery
Note: As soon as the battery weakens, a peep will
sound every minute; when the battery is exhaus-
ted, a longer peep will sound every minute, depen-
ding on which of these events occurs first. In these
cases you should install a new smoke detector.
Important:
Smoke detectors should be replaced every 10 years.
