The TCD 573 (Temperature Criteria Detector) detects fires with and without smoke development. It is the detector of choice where rapid fire development and high temperatures might be expected or when smoke detectors cannot be deployed due to environmental influences. An NTC temperature sensor located in the sampling chamber continuously measures the ambient temperature and rate-of-rise of the temperature. If the set alarm point or the defined rate-of-rise is exceeded, the detector transmits an alarm to the control unit. The detection range can be specifically defined from the control unit. The TCD 573 is available in the three sensitivity ranges – classes A1, A2 and B – in compliance with EN 54-5. All detectors of the three classes detect various differential and maximum measuring procedures.
