The Pyrotector Model 30-2021-24 and Model 30-2021E-24
Ultraviolet (UV) Flame Detectors are highly sensitive to the
ultraviolet radiation given off by all types of flames, including
those produced by flammable liquids and gases. Since the
detector does not respond to normal ambient light conditions
such as sunlight, incandescent or fluorescent lighting, it is ideally
suited for use as a flame detector in a variety of areas.
The Pyrotector Ultraviolet Flame Detector is a compact unitized
package consisting of a detection tube, encapsulated
solid state electronic circuitry, and a dry-contact Form-C
(SPDT) alarm relay. In the event of an alarm, the relay latches
on and an alarm light is illuminated for easy identification of
the unit in the alarm state. The relay is reset by momentarily
interrupting power to the unit. A three-second time delay is
built in to minimize false alarms cause by the presence of
sparks, lightning, etc.
