Table 2. Flame Detection Systems.

a

Flame Failure Response Time (FFRT) depends on selection of amplifier and 7800 SERIES Relay Module.

b

R7824C is used only with the 24 Vdc RM7824 Relay Module and C7024E,F Flame Detectors.

c

Circuitry tests all electronic components in flame detection system (amplifier and detector) 12 times a minute during burner
operation and shuts down burner if detection system fails.

d

Use only Honeywell part no. 38316 Photocell.

e

Circuitry tests flame signal amplifier 12 times a minute during burner operation and shuts down burner if amplifier fails.

f

200/220/240 Vac applications require a 120 Vac, 10 VA minimum stepdown transformer (not provided) to drive the shutter.
Applies to R7847C series 3 or greater; R7886A series 2 or greater; R7861 series 1 or greater. Fig. 2 shows flame detector
wiring.

g

Use C7027, C7035 and C7044 Flame Detectors only on burners that cycle on-off at least once every twenty-four hours. Use
C7012E,F Flame Detector with R7847C Amplifier, C7061A Ultraviolet Detector with R7861A Amplifier or C7076A Flame
Detector with R7886A Amplifier as ultraviolet flame detection system for appliances with burners that remain on continuously
for twenty-four hours or longer.

h

R7847A,B Amplifiers with 0.8/1 second FFRT should not be used with C7012A,C Solid State Ultraviolet Detectors.

i

R7824C Series 2 and greater and R7847C Series 4 and greater check flame detector system when flame reaches 1.5 Vdc or
at 4.5 seconds, whichever occurs first.

j

Order flame rod separately; see flame detector Instructions for holder.
