IR Device mounting Instructions
- Determine the placement of the IR receiver. It will generally be best suited to be positioned in a corner.
- 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
- Remove the mounting hardware from its packaging (necessary mounting hardware shown below)
- Using toggle bolts, secure the mounting plate to the drop ceiling
- Note: If encountering hard ceiling, use anchors and screws (3/16")
- Drill a small hole behind where the IR transmitter will be mounted for passing cables through
- Run 22/2 cable to the IR T1.
- 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.
- Cut a 3.5mm audio cable (approx 12") and strip the jackets to expose the wires
- Splice the 3.5mm audio cable with the 22/2 with B-connectors.
- Cover your splice with electrical tape.
- Attach mount arm the IR reciever
- Place the mount cover over the plate and twist the mounting arm until secure
- Plug the 3.5 cable into the Line In of the IR T1 and connect the power cable
- Return the ceiling tile to it's appropriate location
- 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. 18/2 cable may be needed to add length to the power cable. 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.
Testing the System
- Ensure your IR T1 and RX224 are set to the same channel.
- Test the talkback unit is working by activating the talkback function within the VALT Software and having a partner to communicate with.
