Description
Descrption
400-series non-addressable carbon monoxide (CO) alarms are suitable for connection to 2-wire and 4-wire non-addressable fire detection control and indicating equipment.
Advanced electronics in conjunction with a semiconductor gas sensor provide early detection of carbon monoxide gas and high immunity against unwanted alarms.
