Silent Knight by Honeywell
Farenhyt IDP-FIRE-CO detector senses both fire and carbon monoxide (CO) and delivers customized tone to differentiate between fire and CO events. Detector uses four separate sensors to search for smoke, CO, light/flame, and heat to verify true fire events. Nuisance alarm capabilities reject false alarms based on temperature fluctuations.
