MULTI-CRITERIA DETECTOR(D-MC)
The Godrej Fi-Warn D-MC optical cum heat multi-criteria detector contains an optical smoke sensor and a thermistor temperature sensor.

The Godrej Fi-Warn D-MC optical cum heat multi-criteria detector contains an optical smoke sensor and a thermistor temperature sensor. These outputs are combined to give the final analog value. The combination of the signals of the two sensors depends on the selected response mode. The five modes provide response behavior. This incorporates pure heat detection, pure smoke detection and a combination of both.The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature in the vicinity of the detector. The detector’s micro-controller processes the two signals according to the mode selected. When the detector is operating as a multi-sensor (i.e. modes 1, 3 and 4) the temperature signal processing extracts only the rate-of-rise information for combination with the optical signal. In these modes the detector will not respond to a slow temperature increase – even if the temperature reaches a high level. The multi-criteria istherefore useful over a wide range of applications.
