absence of flame; the frequency of the pulses is a measure of flame intensity. Pulses generated by the
scanner are transmitted to a compatible Fireye control via scanner wiring.

The components are contained in a cast aluminum housing sealed with an oil-resistant gasket. The
quartz lens is a planoconvex design, resulting in increased sensitivity. Also included in the scanner is
an electromagnetic shutter that permits a self-checking circuit to verify that the scanner and signal
circuits are producing valid flame presence or absence information. During the shutter closed period,
the detector’s optical path is blocked from flame radiation, allowing the amplifier control to verify
the proper operation of the ultraviolet tube. While the shutter is open, flame presence or absence is
detected. The resultant scanner output (while flame is detected) is a continuous, periodically inter-
rupted, pulsed flame signal which is a prerequisite for energizing the associated Fireye control’s
Flame Relay.
