C7012A,C,E,F,G Solid State
Purple Peeper®
Ultraviolet Flame Detectors
APPLICATION
The C7012A,C,E,F,G Flame Detectors are solid-state
electronic devices for sensing the ultraviolet radiation emitted
during combustion of most carbon-containing fuels such as
natural gas, LP gas, and oil.
FEATURES
All models
• Solid-state electronic circuitry provides low power
consumption and high reliability.
• Solid-state models directly replace previous models
with vacuum electron tube circuitry.
• Detectors can be mounted horizontally, vertically or
at any angle. The self-checking C7012E,F models
require faceplate alignment and have integral locating
reference points to assure proper shutter mechanism
operation.
• Ultraviolet radiation sensing tube and quartz viewing
window are field replaceable.
• Threaded conduit fitting and color-coded leadwires
allow rapid electrical installation.
• Two flame detectors can be wired in parallel to
reduce nuisance shutdowns in difficult flame
sighting applications.
• A swivel mount is available to facilitate flame sighting.
• Models are available with a -40°F (-40°C) rating.
C7012A,C,G
• Designed for use with Honeywell Flame Safeguard
Controls using Honeywell Rectification (R7247A,
R7289A, R7847A1082) and Ampli-Check™
Rectification (R7247B, R7847B1072) Flame Signal
Amplifiers.
• C7012G models available to meet BGC (British) and
DIN (German) requirements.
C7012E,F
• Incorporate UV sensor tube checking feature; used
with Honeywell Dynamic Self-Check (R7247C, R7847C)
Flame Signal Amplifiers.
