Alarm override switch
Self-contained smoke detector/alarm Cat. No. 0 405 17 has an alarm
override function:
• when the source of the smoke has been identified
• as a preventive measure before smoke is likely to occur
Example: smoke from a toaster, deep fat fryer, cigarette. The override is
automatically disabled after 10 min.
The self-contained smoke detector/alarm then reverts to its normal
operating mode. This allows you to ventilate the room without setting off
the alarm audible signal.
