The FLR500 linear reflection smoke detector is an addressed device for FAP54 series digital control panels (FAP541, FAP544EVO, FAP548EVO and FAP5416EVO). It is particularly suitable for applications in the tertiary sector and in special environments such as museums, historical buildings, etc. The detector contains both the transmission (Tx) and reception (Rx) sections of the infrared signal; its I operating principle is based on the interaction between the smoke present in an environment generated by a fire start and an infrared beam emitted and reflected by a special optical reflector.
