1. Locate the center point of the mounting location and insert the compass tool into the ceiling. Draw a circle.

2. Cut out the circle.

3. Use the mounting ring as a template to mark the screw hole pattern onto the mounting surface. Prepare the holes.

4. Install the mounting plates. Use the eight 10-32 x 3-inch screws (supplied) to install the mounting ring (A) and the two back mounting plates (B).

a. Line up the mounting ring with the eight fastener holes.

b. Feed one back mounting plate (B) through the hole in the ceiling (C). Line up the plate with the four fastener holes.

c. Install fasteners through the mounting ring (A), ceiling, and out the back mounting plate (B).

d. Install the second back mounting plate (B).

5. Attach a conduit fitting (not supplied), lock nut (not supplied), and safety chain bracket. Install a safety chain/cable (not supplied), which will support up to 16 pounds (7.3 kg).

6. Open the hinged door to the back box. Push the tab lock toward the wall of the unit and lift the door open. Pull the wiring into the back box through the conduit fitting. Refer to Table A, Table B, and Table C for wiring distances.

Requirements

Cable Type* Maximum Distance

RG59/U 750 ft (229 m)

RG6/U 1,000 ft (305 m)

RG11/U 1,500 ft (457 m)

*Cable requirements:

75-ohm impedance All-copper center conductor All-copper braided shield with 95% braid coverage

NOTE: Input power for the dome is 24 VAC or 24 VDC. Using 24 VAC input power, power consumption is 23 VA per dome. Using 24 VDC input power, power consumption is 0.7 A (15 W). Use a 24 VAC transformer with a minimum of 40 VA per dome.

NOTE: As a minimum, UTP requires Cat5, 100-ohm twisted pair cable.

Table B. 24 VAC/24VDC Wiring Distances

Below are the recommended maximum distances for 24 VAC and 24 VDC applications and are calculated with a 10 percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for ACor DC-powered devices.)

7. Install the back box by compressing the spring clips and pushing the back box through the hole. Tighten the screws until you hear a clicking noise.

WARNING: An electrical short in the back box may occur if the metal BNC connector is not completely covered by the protective boot.

8. Connect the wiring to the circuit board inside the back box. When finished, close the door to the back box and turn on the power. The green LED will glow.

NOTES:

• Aux 1: Maximum 2 A at low voltage (<40 V)

Aux 2: Maximum 30 mA at 32 VDC

• If you are using both unshielded twisted pair (UTP) wiring and a translator board, install the UTP wiring before

installing the translator board.
