Optical Smoke Detector for Analogue Addressable Fire Alarm System
Optical Smoke Detector for Analogue Addressable Fire Alarm System
CD120 is a conventional smoke detector, adopted non-polarity 2-Wire technology. The design incorporates a highly integrated 8 bit professional MCU which provides powerful analysis & judgment capacity and reliability. Through the firmware, the detector can automatically compensate the external environment parameter changes, synthesize various information, carry on the interference filter, realize more quick and accurate fire warning
