Alarm memory
If the smoke detector had an alarm, this is visually indicated by the
LED until it is acknowledged.
Integrated real-time clock
Suppression of status messages which do not affect the operation of
the smoke detector by the integrated real-time clock between 10 pm
and 6 am CET* in order not to disturb sleep.
Reduced light intensity
Automatic reduction of LED light intensity by means of the integrated
real-time clock between 10 pm and 6 am CET*.
Contamination compensation
The detector controls its basic signal according to its level of con-
tamination and thereby reaches a higher service life than smoke
detectors without compensation. If the maximum contamination
level is reached by the readjustment, this is signalled as a failure.
