Wide area smoke detection
April 1st 2009 The Fireray 2000 EExd is a
beam-type smoke detector
from Fire Fighting
Enterprises. Certified to
ATEX 94/9/EC standard for
use in Group 2 hazardous
areas, it brings the benefits
of wide-area smoke
detection to environments
with a risk of explosion. The
company says warehouses
and and storage depots can
be safely protected by beam
detector systems more
efficiently than traditional
'point' detectors.
Each F2000 EExd is
comprised of three parts – an
infrared transmitter and a
receiver placed on opposing
surfaces, and a low level
control unit, all ATEX
certified. Any smoke entering
the beam path is detected by
the loss of signal strength
between the detector heads,
so product can cover an area
of up to 1500m2: the beam
is effectively 15m wide, and
the heads can be up to 100m
apart. By comparison,
approximately 15 point
detectors would be needed
to cover the same area,
which would greatly increase
the costs of hardware,
cabling, installation and
maintenance.
As with other Fireray
products, the F2000 EExd
has a drift compensation
feature to guard against
gradual loss of signal caused
by dust build-up on the
detectors or building shift,
reducing false alarms. More articles from Fire Fighting Enterprises: |
