Description
Hard Wired - Electrician Installation All the same features and quality as the other Gentex smoke alarm models, with the addition of battery backup. Battery backup operates audible alarm only. This 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. One year warranty. The 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. Features:
- 177 candela rating (very bright strobe light)
- Solid state continuous 90dB horn (very loud)
- Full function test switch (easy for you to test that it is working)
