Photo Electric Smoke Detector

Gentex photoelectric smoke alarm with plug in line cord ada strobe and battery backup 112 37 112 37.

Photo electric smoke detector. Alarm sensor type photoelectric. Experts say photoelectric smoke detectors generally won t cause as many false alarms but for the ultimate in safety they recommend opting for a smoke detector with both types of sensors. Ionization type smoke alarms have a small amount of radioactive material between two electrically charged plates which ionizes the air and causes current to flow between the plates. How do photoelectric smoke detectors work.

Ionization smoke alarms are generally more responsive to flaming fires. In this chamber an led light shoots a beam of light in a straight light across the chamber. A photoelectric or optical smoke detector contains a source of infrared visible or ultraviolet light typically an incandescent light bulb or light emitting diode led a lens and a photoelectric receiver typically a photodiode in spot type detectors all of these components are arranged inside a chamber where air which may contain smoke from a nearby fire flows.

A photoelectric smoke detector is characterized by its use of light to detect fire. Battery type required 9 volt. Photoelectric smoke detectors therefore use light in a different way. The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection.

Inside the alarm there s a light sensing chamber.
