Fewer false alarms
FFE has been awarded a UK patent for the light cancelation technology in its Fireray range of infrared beam smoke detectors.
The technology works by actively monitoring ambient light levels on the detector and ‘subtracting’ them away from the ‘real’ signal. This allows the detector to work under the most difficult light conditions, including sunlight, sodium lamps and fluorescent lighting.
“It’s no exaggeration to say that this technology is unique,” comments FFE research engineer Dr. Daniel Waldron. “No-one else offers ambient light cancellation technology that allows the beam to cope with all manner of challenging light conditions, both natural and man-made. This means fewer false alarms and false readings.”
By using infrared beams, Fireray beam detectors can identify smoke over much larger areas than traditional fire detection devices, making them suited for large indoor spaces such as warehouses.
