A beam detector is used to provide "wide area" smoke detection and is usually used in situations where it is either not practical or not cost effective to use traditional point detectors. A beam of light (usually infra-red) is projected across the area to be protected, any smoke entering the beam cause the beams power to fall, when the power falls to a predetermined level the detector will signal an alarm.
End to End Beam Detectors
An end to end beam detector consists of a transmitter and receiver, these are positioned at opposite ends of the area to be protected. The transmitter emits a signal, which is detected and monitored by the receiver.
Reflected Beam Detectors
A reflected beam detector contains the transmitter and receiver in the same unit (transceiver). The transmitter emits a signal which is reflected back to the transmitter using a reflector positioned at the opposite end of the area to be protected.
