NTRODUCTION
The UV/IRS is a smart, stand-alone fire detector, combining sensors for both
the ultra-violet and infrared spectra. The detector is designed to respond to a
wide range of hydrocarbon based fires and the rugged design is ideal for both
indoor and outdoor applications.
The microcontroller monitors and analyzes each sensor to identify a variety
of flame conditions. Only when the defined detection criteria for both IR and
UV sensors indicate a fire condition will the detector alarm.
Spectral Sensitivity Range
The UV/IRS fire detector responds to UV radiation wavelengths of 185 to
260 nanometres (1850 to 2600 angstroms) and IR radiation in the 4.4 micron
range. Note that UV radiation reaching the earth from the sun does not
extend into the sensitivity range of the detector, nor does radiation from
normal artificial lighting, such as fluorescent, mercury vapour and
incandescent lamps.
Locate Detector
When positioning fire detectors, consider such factors as, distance from the
fire, type of fuel and temperature, as well as any environmental factors which
may influence the detector’s response to radiation.
