Point type smoke

WebThere are two main types of point type smoke detector – Ionisation and Optical detection. Ionization Detectors – have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. WebApr 14, 2024 · Ionization smoke detectors utilize a small amount of radioactive material to ionize air molecules into positively and negatively charged molecules that create a small electric current. The introduction of smoke into that ionized air will reduce the amount of current and cause an alarm signal.
