The Hekatron TCD-573 (Temperature Criteria Detector) can detect fires with and without smoke development. Where rapid fire development and high temperatures might be expected or when Smoke Detectors cannot be deployed due to environmental influences, the Hekatron TCD-573 is the detector of choice.
The Hekatron TCD 573 Heat Detector 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.
