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.
