The RE-428 Series beam smoke detector is designed for smoke detection at the start of a fire. It is especially suitable for protection of indoor spaces, in which the appearance of smoke is likely during ignition of a fire, and where, due to a large space area, installation of a greater number of point smoke detectors would be necessary. The RE-428 Series beam smoke detector and the prism reflector or reflector panel are installed on opposite walls of a room.
