Gentex 7139CS-C

The 7139CS and 7139LS photoelectric single/multiple station smoke alarms are engineered to virtually eliminate nuisance alarms and deliver outstanding performance wherever reliable fire protection is required. The Series has been designed to give reliable early warning of the presence of smoke where both audible and visual alarms are required for residential and commercial residential applications, including homes, apartments, hospitals, hotels and motels. The 7139CS and 7139LS features a 90dBA solid state piezo signal and a 177 candela strobe with “FIRE” lettering. Upon activation, the smoke alarm will emit a 90dBA local audible signal and activate the high intensity strobe. During the alarm period the strobe will flash at a brightness of 177 candela 60 times per minute. The 7139CS and 7139LS provides an exclusive patented three-position test feature that simulates a 0.85% and 3.5% actual smoke condition in full compliance with NFPA 72 and UL Standards. The 7139CS and 7139LS smoke alarms are ANSI/UL 217 and the strobe is listed per ANSI/UL 1971 and are warranted for one year from date of purchase.
