Product Description

The RE-428 Series Optical Ravel Beam Smoke Detector is designed for smoke detection at the early stage of fire. It is particularly suitable for protection of premises where smoke appearance is expected in the first phase of the fire and where installation of a large number of point smoke detectors would be necessary due to a large area. Compared to point smoke detectors, beam detectors are sensitive to a medium smoke density value on a long path of the infrared radiation beam. Therefore they are especially suitable for application under high ceilings/roofs or in those places, where smoke can be diffused over a large area before detection.

Examples of applications, where this type of detectors can be particularly useful, include: churches, cathedrals, monumental buildings with valuable historic ceilings, theatres, sports halls, industrial shops, very high rooms, in which point detectors would not be effective, and rooms with a differentiated ceiling or roof design.

A distinctive feature of the RE-428 Series beam detector is its arrangement of transmitter and receiver in one housing and interaction with a prism reflector or a reflector panel placed on the opposite wall. A single casing embraces a laser pointer that enables optical path axis alignment between the detector and the reflector/set of reflectors.

The RE-428 Series optical beam smoke detector is intended to interoperate with any fire detection and alarm control panel that ensures power supply in the range between 9.5 V and 28 V and current > 100 mA. The alarm signal is the relay non-potential contact switch over. The detector operates in closed premises at ambient temperatures ranging from 25o C to +55o C and relative humidity .
