Description
With a range of 5m to 70m the Beam Smoke Detector
6500R serves for the monitoring of open spaces. The
transmitter/receiver unit projects a pulsed infrared light
beam through the area to be protected towards a refl ec-
tor, which returns the light beam. The smoke detection
is based on the attenuation of the light beam by means
of smoke.
The detector uses intelligent evaluation algorithms to
compensate for the infl uence of contamination of the
optical measurement system. With that, the response
sensitivity of the detector is kept constant for a long
time – an effective step to avoid false alarms.
Conventional technology is used for alarm transmission
to the fi re detection control panel. The response sen-
sitivity of the detector can be set to one of six levels.
Four levels have a fi xed response threshold, whereas
two further levels with variable response sensitivity al-
low to adjust the detector to changing environmental
conditions.
The detector is delivered with a refl ector, which can be
used for ranges from 5m to 70m. A three-part refl ector
set, which extends the range of the detector to 100m,
is available as accessory.
The Beam Smoke Detector 6500RS corresponds to the
Beam Smoke Detector 6500R in design and function.
In addition, the 6500RS can be remotely activated, al-
lowing easy function testing during maintenance. This
test simulates light obscuration by means of a motor-
driven test fi lter.
