Abstract:

Commercial fire detection systems are typically designed to sense temperature, airborne particulates, or electromagnetic radiaiton at prescribed locations in a room. Temperature sensors are based upon thermistors and thermocouples, or can be mechanical in nature (e.g. the fusible link in a sprinkler head). Airborne particulates can be sensed by the attenuation of light, the scattering of light, or the change in ionization from a radioactive source. flame detectors, which are not noramlly used in aircraft cargo areas or telecommunication equipment, sense electromagnetic radiation in the infrared and/or ultraviolet spectrum. Comprehensive discussions of these and alternative fire sensing methods and their applications can be found in a number of review articles.
