WebSep 24, 2012 · Ionisation-type smoke detectors are the most inexpensive type of detector and probably the most common. The sensors release a tiny amount of radiation (around … WebWhen smoke molecules enter the ionization chamber, the smoke particles attach to the ions and neutralize them. Consequently, the total number of ionized particles in the chamber is reduced. This reduction yields a decrease in the chamber current that is sensed by the electronic circuitry. The drop of current between the plates triggers an alarm.

WebIonisation smoke alarms contain a small amount of radioactive material between two electrically-charged plates. This material ionises the air, causing a current between the plates. When smoke enters the chamber the flow is disrupted and the alarm is activated. WebIonization smoke alarms monitor “ions” or electrically charged particles. Smoke particles change the electrical balance of the air. The alarm will sound when the change in electrical balance reaches a preset level. (IFSTA Fire and Life Safety Educator Pg 38) Photoelectric smoke alarms use a beam of light and a light sensor.
