Device for recognising fires in switching cabinets

摘要

The device has a suction pipe system for communicating with an electrical cabinet (100) to be monitored by a suction opening and a representative air sample extracted from the cabinet through the pipe system. An early fire detection module (10) has a detection unit (11) arranged as a modular unit for detecting a fire parameter in the air sample. A controller (12) transfers an early fire detection signal in response to the detected output from the detector unit, where the module is arranged as an insertion rack for inserting into the cabinet.
