Description
TheRE-428 Series beam smoke detector is designed for smoke detection at the start of a fire. It is especiallysuitable for protection of indoor spaces, in which the appearance of smoke is likely during ignition of a fire, andwhere, due to a large space area, installation of a greater number of point smoke detectors would benecessary.The RE-428 Series beam smoke detector and the prism reflector or reflector panel are installed on opposite,walls of a room.Special adjusting screws are provided at the detector and the reflector panel for precise alignment of the detector
and the reflector/s in the optical path. A special laser target viewfinder is actuated at the moment when the optical beam path is aligned.The RE-428 Seriesdetector consists of an infrared (IR) light transmitter and a receiver located in a single housing
and an interoperating prism reflector

Qutak QT BD2606 Beam Detector With 4 reflectors
Beam Detector With 4 reflectors is an optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building.

C-9105R Conventional Reflective Beam Detector
C-9105R Conventional Reflective Beam Detector is an addressable reflective infrared beam smoke detector that can be directly connected to a fire alarm controller, by transmitting status information via a bus between the detector and controller. The detector must be used together with a reflector. The number of reflectors (s) to be used (one or four) depends on the distance from the detector. With a built-in intelligent microprocessor, the detector has a strong ability for analysis and judgment.
