Atexbeam-typedetector
May 1st 2009 The Fireray 2000 EExd beam-type
smoke detector from Fire Fighting
Enterprises is certified to ATEX
94/9/EC standard for use in Group 2
hazardous areas, bringing the
benefits of wide-area smoke
detection to environments with a
risk of explosion.
Each F2000 EExd is comprised of
three parts – an infrared transmitter,
a receiver placed on opposing
surfaces, and a low level control unit.
Any smoke entering the beam path is
detected by the loss of signal strength
between the detector heads, so one
product can cover an area of up to
1500m2; the beam is effectively 15m
wide, and the heads can be up to
100m apart. In 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.
A drift compensation feature
guards against gradual loss of signal
caused by dust build-up on the
detectors or building shift, reducing
the incidence of false alarms. More articles from Fire Fighting Enterprises Ltd: |
