WebSep 24, 2012 · Ionisation Smoke Detectors. 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 1/5000th of a gram) to ionise the air inside the sensor. If there is a fire, ions in the smoke will attach themselves to the ions in the sensor and trigger the ... WebMar 27, 2024 · For a reliable, long-lasting, and effective smoke detector, we recommend the First Alert BRK 3120B Smoke Detector. This 10-year, hardwired model is equipped with both a photoelectric and an ionization sensor. “Dual detectors allow the device to detect both smoky fires and flames,” says Mock.

WebThe detector emits a beam of infrared or ultraviolet light, which is received either by itself or by a receiving reflector. If the received light beam is weaker due to smoke, the detector will trigger an alarm. Optical detectors can often be found combined with a heat sensor. Such variant significantly lowers the probability of a false alarm. WebDownload Kidde K85001-0652 -- Intelligent FX Detectors and Bases PDF.
