Silent Knight SK-FIRE-CO-W Multi-Criteria CO and Smoke Sensor (White)The Silent Knight SK FIRE CO W is an addressable, plug in multi criteria detector that provides both fire and carbon monoxide (CO) detection in a single device. It combines four independent sensing elementsphotoelectric smoke, thermal (fixed temperature and rate of rise), infrared (IR), and electrochemical COto improve real fire detection while reducing nuisance alarms. Advanced onboard algorithms analyze inputs from all four sensors to enhance
