IPC: G08B17/10
Filed: 2022-05-16
Abstract: The invention relates to a method for operating an aspirating smoke detector (ASD), an aspirating smoke detector corresponding thereto and a computer program product (PRG). Ambient air is aspirated by means of a suction unit (L) via a suction pipe (R) provided with suction openings (OF) and is fed to a fire detector unit (DET) for determining a signal level (DL). For normal operation, the suction power (P) is set to a nominal airflow value (NW) and this is increased from a minimum signal level value (MIN) in order to shorten the transport time (T) of aspirated smoke through the suction pipe to the fire detector unit. According to the invention, an interruption signal (U) provided for normal operation is output, in particular according to the standards EN 54- 20:2009-02 or UL268, 6th or 7th edition, if the airflow (P, th ) exceeds an upper limit value (P+, th+) for a minimum period (ZR). Independently thereof, the suction power is increased from the minimum signal level value only to the extent that the airflow does not exceed the upper limit value. Or, regardless thereof, the suction power is increased only for a timespan smaller than the minimum period in which the airflow exceeds the upper limit value.
