UNIPHOS-400 multiparameter UV/IR based Fire Detector detects fire by detecting simultaneously three important characteristics of fire viz. UV radiation in the solar blind region of 185-260 nm， IR emission from the hot CO2 which invariably is present in and around a fire and the continuum black body IR radiation from the fire. This microprocessor based detector is housed in a flameproof enclosure with a viewing window. It is mounted on a wall mountable stand with provision to adjust the field of view to bring the viewing window in line of sight of the likely spot where fire can occur. The detector gives a fire alarm (red led glows) when all the three chosen fire parameters are detected. Simultaneously a relay output is available. When any one of IR or UV radiation is detected yellow led glows to give a warn alarm and also a relay output is available. The detector also provides an analog 4-20mA output and a RS485 digital output to indicate the above events.
