The Series 65 Base Mounted Ultraviolet (UV) Flame Detector is designed to protect internal areas where flaming fires may be expected.
The detector is sensitive to ultraviolet radiation emitted by flames during combustion. Since it requires only UV radiation, the Flame Detector also responds to stationary flames with no flicker such as cigarette lighters and blue gas flames. The detector is set to respond to ultraviolet radiation (185 to 260nm) emitted by almost all flames, including those invisible to the naked eye, e.g. hydrogen fires.
The detector has a single UV sensor with a narrow spectra response in order to discriminate between flames and most spurious sources of radiation and is designed for internal fully enclosed areas.
Caution: The detector will also detect electrical discharges from lightning or arc welding.
Note: When using the detector the following must be avoided; outside viewing, UV lamps, electrical sparkling, welding and sources of radiation, UV light sources, prolonged ambient temperatures above 60ºC, and obstructions to the field of view.
