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.
