Installation Instructions

Connecting to the Camera

1. Once the camera is installed, locate the AUDIO OUT on your camera
2. Strip the jacket of the 22/2 cable revealing the red, black, and bare wires inside.
3. Cut away the bare wire and plastic surround the cable inside. Strip away a small piece of the red and black jackets revealing the bare copper wire.
4. Wire the black and ground to the - and the red to the + of the AUDIO OUT of phoenix connector or splice to 3.5mm with B-Connectors d.

IR Device mounting Instructions

1. Determine the placement of the IR receiver. It will generally be best suited to be positioned in a corner.
2. Remove the drop ceiling tile to which the IR receiver will be mounted

   Note: The IR receiver will be mounted as far back to the corner as space allows

3. Remove the mounting hardware from its packaging (necessary mounting hardware shown below)

   

4. Using toggle bolts, secure the mounting plate to the drop ceiling

   Note: If encountering hard ceiling, use anchors and screws (3/16")

   

5. Drill a small hole behind where the IR transmitter will be mounted for passing cables through

   

6. Run 22/2 cable to the IR T1.
7. Strip about an inch of white jacket off the 22/2, as well as about 1/2 inch of the colored jackets to expose the wire.
8. Cut a 3.5mm audio cable (approx 12") and strip the jackets to expose the wires
9. Splice the 3.5mm audio cable with the 22/2 with B-connectors.

   

10. Cover your splice with electrical tape.
11. Attach mount arm the IR reciever

    

12. Place the mount cover over the plate and twist the mounting arm until secure

    

13. Plug the 3.5 cable into the Line In of the IR T1 and connect the power cable

    

14. Return the ceiling tile to it's appropriate location

    

15. Once audio is plugged in, locate your nearest power outlet to power the IR T1.

    Note: The IR transmitter is powered by a standard 5v USB phone style charger that needs a regular wall outlet, or a connection to a POE line with a POE splitter to power it.

POE Splitter

1. Locate the network drop above the ceiling. Determine the best location to mount the POE splitter in relation to the IR receiver.
2. Mount the POE splitter
3. If there is power above the ceiling within five feet of the mount location, connect the POE splitter to power
4. If there is not power above the ceiling, locate the nearest and most appropriate location to run a line for power.
5. Cut a length of 18/2 long enough to reach from the POE splitter to the power outlet.
6. Cut a small hole above the ceiling near the POE splitter for the 18/2 to pass through
7. Using a stud finder, scan the wall near the power outlet to determine the best path to run the cable.
8. Cut a hole into the drywall at the same height as the power outlet and large enough to fit the mud ring into it securely

   .

9. Using fish tape or glow rods, pass the 18/2 behind the drywall
10. Strip the ends of the 18/2 and splice with the RDL 24v power supply and splice with B-connectors
11. Cover the cable splice with electrical tape
12. Follow the same two previous steps with the power supply cable for the POE splitter

    Note: Ensure that when splicing in the 18/2 to the power, that the red jacket of the 18/2 is spliced into the cable with the dashed white lines on the power supply. The power cables will need to be tested for power continuity.

13. Mount the pass through plate and place any excess cabling for the RDL 24v power supply through the plate.

Testing the System

1. Ensure your IR T1 and reciever are set to the same channel.
2. Test the talkback unit is working by activating the talkback function within the VALT Software and having a partner to communicate with.
