electronicsensorautomatic

For the early detection of smoke-generating, flaming and smoldering fires. Works according to the scattered-light principle with one sensor, optical forward scattering. Opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects smoke particles. Signal processing with detection algorithms (DA). The base must be ordered separately. Also available in different colors.
