The BDH160 detector is a self-aligning linear optical device designed for smoke detection over long distances using transreflective infrared technology. The integrated motorized head allows self-alignment during installation and self-correction over time to compensate for any structural movements. The system consists of a head with IR transmitter/receiver, a ground control unit, and reflectors. The emitted infrared beam is reflected by the reflector and analyzed to detect the presence of smoke. Standard range covers 5 to 70 m, extendable to 160 m with additional reflectors. The BDH160 is compatible with Inim loop via EU311 module, can be powered separately or via loop, and allows management of up to 20 detectors per loop (to be verified with dedicated software).
