The IR/UV Based Fire Detector easily detects fire by detecting its three critical features such as IR emission from the hot CO2, UV radiation (185 mm to 260 mm) in the area surrounding the solar bind and continuum black body generated by IR radiation emanating from fire. Having a flameproof enclosure (with two windows), the Fire Detector can be easily mounted on a wall with the help of a stand; this stand’s view can be adjusted for bringing the viewing window in the line of sight of the spot where fire outbreaks can happen.
Working : 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 only 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 MODBUS RS485 digital output to indicate the above events.
