FIREGUARD’S ultra-violet (UV) flame detector delivers protection you can trust-the protection you need! The detector reacts to the UV radiation found in hydrocarbon fires, delivering accurate and reliable fire monitoring. Its smart sensor technology even detects hard to see hydrogen, ammonia and sulphur fires. As an added advantage, the UVS does not react when exposed to incandescent or fluorescent lighting, heaters or sunlight-so false alarms are virtually eliminated.
