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.
