Eaton's Optical Smoke Beam Detector for conventional fire alarm systems is designed to replace individual point detectors in large, open areas, such as warehouses.
Extremely simple to install, the beam detector requires no separate power supply and features an easy alignment installation process. Fire and fault conditions are signalled to the control panel using standard loop wiring, so no additional interconnection required.
Two options are available in the range with two different ranges: up to 50 metres for smaller areas and up to 100 metres for larger spaces.
The detector features two parts: a transmitter-receiver and reflector. The transmitter-receiver directs a continuous infra-red beam towards the reflector which utilising a prism then sends back the beam to the transmitter-receiver which in turn registers the strength of the beam.
A fire or fault is signalled when the continuous beam is interfered between the two parts by smoke; reducing the strength of the beam. The transmitter-receiver is preset to indicate a fire or fault when the beam's strength is below a certain value.
