Gentex 710CS Hard Wired Wall Mount Smoke Alarm

Hard Wired - Electrician Installation
The 710CS is a photoelectric single station smoke alarm 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.A photoelectric smoke alarm 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.
