How does a smoke detector work? The way it senses the fire depends on the type of detector it is.
It has a small amount of radioactive material between two electrically charged plates, which ionize's the air and causes current to flow between the plates. Many also include a battery backup system to keep it functioning during power outages. Smoke detector, device used to warn occupants of a building of the presence of a fire before it reaches a rapidly spreading stage and inhibits escape or attempts to extinguish it. There are two main types of smoke detectors: The first smoke detector type, ionization alarms are generally more responsive to a flaming fire (for instance, when a lit candle tips over and ignites a curtain), according to the national fire protection association (nfpa).
Ionization vs photoelectric from www.nfpa.org There are alos photo diodes, which function as light detectors but without the gain photo transistors can provide.

Commercial, industrial, and mass residential devices issue a signal to the main function of a standalone smoke alarm is to alert persons at risk. You should insure that the batteries are charged and that the smoke detector is functioning properly at least once a month if not more often. When smoke enters a photoelectric smoke detector, however, smoke particles scatter the light and cause some amount of light to hit the sensor. This type uses pipe and fan based system in order to draw smoke particles into the detection system. There are alos photo diodes, which function as light detectors but without the gain photo transistors can provide. Some smoke detectors are powered by a battery in the unit, while others are directly connected to the house current. The light sits at an angle away from the sensor. Inside this circular device is an enclosed space where, on one end, a beam of infrared light (or light from a led) travels unblocked toward the other end of the enclosure where a photodiode (a tiny, tubular component that turns light into electric current) is mounted. The vivint smoke detector is part of a home security package that connects your smoke detector with other security features, including 24/7 expert professional monitoring, to keep you and your family safe.
