Autronica 20-20U UV Flame Detector
The Autronica 20/20U is obsolete, and is replaced by the Autronica 40/40U Flame Detector
and the Autronica 40/40-001 Mounting Bracket.
Autronica 20-20U (and UB) UV flame detector
responds to high energy UV radiation emitted by fires and by explosions at the point of ignition. Detects hydrocarbon-based fuel and gas fires, invisible hydrogen flames, hydride, ammonia, silane and other inorganic fuel fires. The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
