The I-9105R Intelligent Reflective Beam Detector with adjustable sensitivity and an operational range of between 8 and 100 metres, the device works on the principle of reflective infrared beam obscuration. Used in conjunction with a reflector(s), it will notify the fire alarm panel when the infrared beam is obscured by smoke. Secure and quick communication through the onboard processor enables the detector to make its own decision, resulting in greater automation. The sensor and the panels utilize ‘fuzzy logic’-providing almost limitless cause and effect scenarios. This device is ideal for use in areas where ceiling height exceeds 6 metres, Ideal applications include historical buildings, warehouses, large storages, shopping malls, leisure centres, exhibition halls, hotel lobbies, printing houses, clothing factories, museums and prisons, as well as places where slight smoke particles or corrosive gas exist.
