Fire Detector

Listing ID #1437394

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.
