Viewing heads are wired to the appropriate terminals located 

on bottom of the 700ACSP, 700DCSP, P531 or P532 signal 

processors. The terminals are listed functionally in Table 2.

Connectors and cables are shown in Fig. 3, Fig. 4, and Fig. 5. 

Fig. 3 shows the viewing head cable with the 1/2 in. NPT pipe 

fitting and pigtail for use in a conduit. The PF model comes 

with 50 feet of Honeywell C330S cable. This cable is 

recommended for all new installations. It has ITC and CIC 

ratings for hazardous location. Figs. 4 and 5 describe the 

C330S cable used with the right angle field-wireable 

connector. Refer to “Accessories” on page 9 for part numbers.

The customer may also supply his own cable; a replacement 

mating viewing head connector should be ordered. Refer to 

“Accessories” on page 9 for part numbers.

 

The use of 22g, 4-

conductor cable with shield and drain is recommended. The 

shield should be foil and braid type surrounding all 

conductors. The shield should be connected to GND at the 

processor end. The cable diameter should not exceed 0.307" 

in order for it to go through the hex bushing in the connector. 

But note that wiring the cable to the connector is not easy 

because of the limited space. Also, the LED indicator 

assembly must be mounted inside the connector and, 

preferably, soldered in place. Thus, it is recommended to 

purchase a pre-wired cable and connector assembly from 

Honeywell.

In the U.S., cables should have UL’s ITC rating; in Canada, 

cables should have CSA’s CIC rating. The recommended 

C330S cable has both ratings.
