SECURING THE MASTER PANEL
1. Refer to Figure 26. Inspect all wiring connections to make
sure they are complete and correct.
2. Make sure all antenna connections are secure.
3. Dress all remote station wires flat against the terminal
board.
4. Position the master station panel over the rough-in frame
and align screw holes in master with mounting brackets.
Two (2) mounting holes are located behind the CD
Player door.
5. Secure the master station panel to the rough-in mounting
brackets with four (4) screws (provided).
NOTE: The mounting screws will pierce the wall surface
behind the mounting brackets. If the wall surface is hard, a
clearance hole must be drilled behind the mounting bracket
before securing the master station panel.
POWERING UP THE SYSTEM
Once all connections have been completed throughout the
system, it is time to apply power to the master station.
1. Apply power to the master station by turning on the circuit
breaker that supplies power to the transformers in the
IR-105 rough-in frame.
2. When power is first applied, the LCD display will flash
1:00 PM. Refer to the Operational Checkout section of
this manual for additional information.
MOUNTING AND CONNECTING
OPTIONAL DOOR RELEASE PUSHBUTTON
You have previously prepared the master station for the
optional release pushbutton.
1. Refer to Figure 24. Feed one wire from the door release
transformer and one wire from the door release mechanism
through the pushbutton hole in the master station panel.
2. Connect the two (2) wires to the PB1WHCL pushbutton.
3. Rotate the pushbutton so the screws are on the top and
bottom as illustrated, then snap the button into the
mounting hole.
CONNECTING THE MEMORY
BACK UP BATTERY
Refer to Figure 25. Connect the 2-pin plug from the battery
to the connector located on the control circuit board.
