A major chemical treatment
centre in Budapest is using a
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 Fire
Fighting Enterprises’
Hungarian distributor
Elektrovill
Biztonságtechnikai Zrt. The
beam detectors are being
used to cover large, open
areas of the centre, as the
wall-mounting and massive
detection area per unit make
them an efficient and
effective option.

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.

In the treatment centre,
detectors are situated in
warehousing and storage
areas, which have the type of
open-plan architecture and
high ceilings that make the
most of the beam detectors’
particular features.

Although not necessary in
this instance, ATEXapproved
Fireray models are
also available for use in
explosion-risk environments.
