3.2.2 Hard-Wire or Remote Receiver/Driver

Refer to Figures 6 and 7 for wiring diagrams.

Refer to Table A for the type of video coaxial cable to use.

On models for suspended ceilings or hard ceilings, a plate is provided on the top of the back box with 1/2" and 3/4" conduit knockouts.

If your back box has a power switch, make sure it is off before wiring power to the back box.

A minimum of eleven (11) conductors plus coax are required for pan/tilt, motorized zoom lens and camera power. Dome drives with presets (PP) require an additional six (6) conductors for Type D or seven (7) conductors for Type E. The above does not include the conductor requirements for heaters/blower which will need an addi- tional two (2) plus ground.

The following cable distances are approximate and does not account for heaters/ blower.

Calculations are based on a 10% cable loss with both motors running.
