Detection of blockages and interruptions in an aspirating smoke detector (ASD)

The method involves sucking the air by a fan (3) over a pipe system (1) from chambers and units to be monitored. The air flow of the part of the sucked air and the air temperature (T) are measured. The speed of the air is increased with increased air temperature and is lowered with decreased air tem...

Zusammenfassung:The method involves sucking the air by a fan (3) over a pipe system (1) from chambers and units to be monitored. The air flow of the part of the sucked air and the air temperature (T) are measured. The speed of the air is increased with increased air temperature and is lowered with decreased air temperature. An independent claim is also included for an intake smoke detector with a detecting unit.
