Description
With a range of 5m to 70m the Beam Smoke Detector
6500 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.
The Beam Smoke Detector 6500 does not need an
external power supply and can be connected directly
to the ADM loop with System Sensor/200 protocol. An
integrated dual-isolator can be activated by removing
two jumpers.
The response sensitivity 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 re-
sponse sensitivity allow to adjust the detector to chan-
ging 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 6500S corresponds to the
Beam Smoke Detector 6500 in design and function. In
addition, the 6500S can be remotely activated from
the fi re detection control panel, allowing easy function
testing during maintenance. This test simulates light
obscuration by means of a motor-driven test fi lter. An
external power supply is needed for the test unit, which
can not be powered by the loop.
