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.
