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.
