UV/IR detectors like the Det-Tronics were invented in the mid 1980’s and are the most widely installed flame detectors in the world but can be blinded by soot particles present in smoky fires. These detectors are also limited in their detection range and can detect a standard 1ft x 1 ft N-heptane fire at about 50 feet. UV/IR detectors are best suited to detect fires from clean burning fuels and smaller spaces.
The Det-Tronics X3301, represented by Spartan in western Canada is a multi-spectrum infrared detector that sees fires through smoke more accurately than UV/IR detectors. This detector is best suited for applications that have large coverage areas, fuels that create smoke when they burn, or highly congested areas where a detector may only see a portion of the fire. The Det-Tronics X3301 is far more sensitive to fire than conventional detectors, is able to detect a fire one forth the size at the same distance as a UV/IR and it has greater false alarm resistance.
