Beam smoke detectors

A major chemical treatment centre in Budapest, Hungary is using FIRERAY 5000 and 14 FIRERAY F50R reflective infrared beam smoke detectors as part of its fire protection system. The system was designed and installed by Hungarian Fire Fighting Enterprises distributor Elektrovill Biztonságtechnikai Zrt. The beam detectors cover large, open areas of the centre, as the wall-mounting and massive detection area per unit make them a more efficient and effective option in such an environment.

Each FIRERAY F50R unit can protect an area of up to 750m2 from a single wired installation point on a wall near the ceiling. The F50R hosts the IR beam transmitter and receiver in the same housing, with the beam being aimed at a prismatic reflector plate on the opposite wall to the unit.

Smoke entering the beam path causes interference and reduction in signal strength, resulting in an alarm signal when a preset threshold is reached.
