The AD-500 cabinet is designed to be mounted two ways:
• The unit can be mounted directly to a wall or flat surface.
• The unit can be mounted recessed in the wall.
Choose a well lit location near the controlled opening. Wiring access for
power, telephone, earth ground, and control output must be available to
the mounting location.

The unit's main circuit board contains static sensitive electronic
components that can be damaged or destroyed by static discharges
during installation. Discharge the static electricity from your body by
touching a grounded object before handling the unit's circuit board.

Before mounting the system, the main circuit board must be removed to
provide access for the wiring hole and mounting fasteners.
!
CAUTION: Touch a grounded object before proceeding to
discharge static electricity from your body.
1. Carefully remove the six main circuit board wiring harness
connectors.
• The 2-pin postal switch connector.
• The 16-pin display connector.
• The 7-pin keypad connector.
• The 8-pin keypad lighting connector.
• The 3-pin speaker connector.
• The 2-pin microphone connector.
2. Remove the six circuit board screws. Note how the green ground
wire lugs are connected with the upper left screw.
3. Carefully remove the circuit board. Hold it by the edges. Set it aside
in a safe place.
Reverse these steps to replace the circuit board after the cabinet
mounting is complete and the system wiring has been routed into the
panel.

The cabinet can be mounted on a wall or any suitable flat surface. The
four 3/8" mounting holes or the four self-drill locations can be used to
attach the cabinet to the surface.
1. For wall mounting, hold the cabinet at the approximate mounting
location where the display will be about eye level or slightly above.
2A. If using the 3/8" mounting holes, mark the four mounting hole
centers. Drill as required. Use the appropriate fasteners for the
mounting surface.
2B. If using the self-drill mounting holes, choose the correct size bit for
the fasteners and drill the cabinet as required. Use the appropriate
fasteners for the mounting surface to secure the cabinet.
!
CAUTION: After drilling, remove any metal chips from the
inside of the cabinet.
3. After routing the wiring into the cabinet, replace the circuit board
and plug in each wiring connector. Be sure to replace the green
ground wire.
