Edwards SIGA-HCD Multisensor Heat and CO DetectorThe Edwards EST SIGA HCD Intelligent Multisensor Heat and CO Detector is an addressable life safety detector designed to provide both fire detection and carbon monoxide monitoring in a single device. The detector combines rate of rise heat sensing with carbon monoxide (CO) detection, allowing it to identify developing fires while also monitoring for dangerous CO gas levels. Part of the Edwards Signature Series, the SIGA HCD collects analog data from
