Honeywell Model 700/800 Signal Processor and Viewing Head USER MANUAL • Model 700ACSP Universal 85-265 VAC powered, plus 24VDC backup. • Model 700DCSP 22-26VDC powered, plus 24VDC backup. The two Model 700 signal processors are similar, with 12 push-buttons, a two-digit numeric display, and four LED status indicators for operator interface. The only difference between the two is that one accepts AC power and the other accepts DC power. Both models also accept 24VDC backup power.

HONEYWELL MODEL 700/800 SIGNAL PROCESSOR AND VIEWING HEAD ACCESSORIES position has been decided. A continuous flow of air must be maintained in order to reduce the conducted heat and to keep the sight pipe and viewing head lens free of dirt and debris. Air required is about 5 SCFM (0.13 Nm3 /min) delivered at 1 in. (25mm) above the maximum pressure as measured at the “Y” or “T” section of the purge air connection for each viewing head.

Contact your distributor or the factory for selection assistance. If a good count ratio between BNR-ON and BNR-OFF cannot be obtained when using an IR viewing head—particularly when monitoring oil flames—an IR viewing head with the High Frequency (HF) filter option is recommended.
HONEYWELL MODEL 700/800 SIGNAL PROCESSOR AND VIEWING HEAD Self-Checking ring to hold it in place so that it is sandwiched tightly between the two retaining rings. The self-check circuitry guards against internal component failure. There are several tasks that require intelligent interaction between the viewing heads and the signal processor. If all of these interactions do not occur properly, the viewing head will not send pulses back to the signal processor and the flame relay will open.
