Gentex 7139CSC Smoke Detector

$148.00

 

Hard-wired for Ceiling Mount
The 7139CSC is a photoelectric single station smoke detector designed to give reliable early warning of the presence of smoke where both audible and visual alarms are required. This model is hard-wired so you would need an electrician to hook it up. One year warranty.

The smoke detector operates on the light scattering principle, a superior method of detection in smoldering fires. It has a pulsing LED light source and a photodiode sensor in a fully screened sensing chamber. When smoke enters the chamber, the infrared beam is deflected onto the sensor. The LED rate increases to 8 times the normal pulse rate, and after the photodiode confirms the presence of smoke for 2 consecutive pulses, it will produce the signal necessary to trip the audible and strobe light alarms.

The 7139 series provides the temporal 3 evacuation tone as a standard feature. When testing, it may take up to 16 seconds longer to go in or out of alarm.

• 177 candela rating (very bright strobe light)
