AD-C1200 and AD-C1200BB Installation

The AD-C1200BB back box is designed to be pre-installed into the ceiling and wired. The AD-C1200 Loudspeaker Baffle assembly is plugged into and secured to the back box at a later time.

AD-C1200BB Installation

The AD-C1200BB installation should be done by a licensed installation professional and wiring installed by a licensed electrician in accordance with local building codes.

1.There are 5 wiring ½" & ¾" knockout locations available on the AD-C1200BB (Figure 10) . Remove the knockout(s) through which the facility’s loudspeaker signal wires are to be routed.

2.Skip this step if you are using electrical conduit for the facility’s loudspeaker signal wiring. Install a Wire Clamp Fitting into the selected knockout holes.

Caution: The AD-C1200BB back box weighs 53 pounds (24 kg). Be sure to use proper safety precautions during installation.

3.Secure the AD-C1200BB back box, using the suspension straps, to a structure able to support ten times combined weight (78 lbs.) of the AD-C1200BB (Figure 10) and the AD-C1200 loudspeaker baffle assembly (Figure 9) .

4.Route the facility’s loudspeaker signal wires through the knockout hole(s) and to the ceramic terminal block.

•If you are using Wire Clamp Fittings, make sure there is enough wire to strip, tin, and connect the wires to the ceramic terminal block. Do not secure the Wire Clamp Fitting at this time.

•If you are using electrical conduit, secure the conduit to the back box.

5.Strip the ends of the wires to approximately 0.4" (10 mm), and tin the ends of the wires.

6.There are two wires already connected to the terminal block; the striped wire is negative, the solid color wire is positive (Figure 24) . Do not remove these wires, but ensure the locking screws are tight. Connect the facility’s loudspeaker signal wires to proper corresponding connections in the terminal block using a #1 Phillips head screwdriver.

Note: For daisy-chaining loudspeakers, insert the extra wires into the same connections as the facility’s loudspeaker signal wires described in these steps.

7. If you are using a Wire Clamp Fitting, secure it and make sure there is enough slack in the wires inside the box to provide for stress relief.
