SafeFlame Detection

SafeFlame’s triple IR (IR3) flame detector compares three specific wavelength bands within the IR spectral three specific wavelength bands within the IR spectral range of a fire and their ratio to each other. This offers fast response without the fear of typical false alarms.

The SafeFlame IR 3 detectors can detect a 0.1m2 (1ft2) gasoline pan fire at up to 60m (200ft) in less than 5 seconds. SafeFlame’s IR3 detector is designed to ignore constant background IR radiation, which is present in all environments.

Instead the detector measures the modulated part of the radiation of a fire. When exposed to modulated non flame IR radiation, IR and UV/IR detectors become more prone to false alarms, while IR3 detectors become more immune to false alarms.

One sensor monitors the 4.4 micrometer range and the other sensors monitor the bands above and below. This advanced technology allows the detector to distinguish between non flame IR sources, and flames that emit hot carbon dioxide in the combustion process (which have a spectral characteristic peak at 4.4 micrometers).
