The cabinet can be mounted recessed using the accessory trim-ring
(P/N IRAD-500). The trim-ring mounts in the wall and the cabinet attaches
to the trim-ring.
1. Identify the location of any studs in the wall.
2. Cut a 13" high by 11" wide rectangular hole between studs at the
mounting location.
3. Install any additional mounting material required to provide
surfaces inside the wall 11" apart for attaching the trim-ring.
4. Place the trim-ring in the wall hole. Check for level, then attach the
trim-ring with up to six screws into the side tabs.
5. Drill 3/16" holes in the cabinet's six pre-marked location.
!
CAUTION: After drilling, remove any metal clips from the
inside of the cabinet.
6. Route the wiring through the trim-ring and into the cabinet through
the center wiring hole.
7. Attach the cabinet to the trim-ring using self-tapping screws
supplied.
8. Replace the circuit board and plug in each wiring connector. Be sure
to replace the green ground wires.

Either or both of the two relay output channels (A or B) can be used to
control door or gate access. Relay Channel "B" can be used for alarm
control functions
Door or Pedestrian Gate Control
1. Install a low voltage electric door strike or magnetic lock as a
locking device for the door or pedestrian gate.
2. Install the power supply or transformer for the locking device. DO
NOT POWER THE AD-500 FROM THIS POWER SUPPLY.
3. Connect one wire from the power supply to one wire from the
locking device.
4. Route two wires between the locking device and the AD-500.
Connect one wire to the remaining wire of the locking device.
Connect the other wire to the remaining wire of the power supply.
5A. For a door strike, connect the wires to the AD-500 relay COM &
N.O. terminals.
5B. For a magnetic lock, connect the wires to the AD-500 relay COM &
N.C. terminals.
Request-to-Exit Inputs
Each relay output has a request-to-exit input terminal. Grounding this
terminal will activate the associated relay. These inputs are typically used
with push bars, loop sensors, or pushbuttons.
1. Install the pushbutton or device to signal an exit request.
2. Route two wires from the device to the AD-500.
3. Connect the device's normally open output to the wires.
4A. To activate Relay Channel "A", connect the wires to the RTE-A and
GND terminals.
5A. To activate Relay Channel "B", connect the wires to the RTE-B and
GND terminals.
Sensing Input
The sensing input connects to a door switch that monitors whether the
controlled door is open or closed. The sensing input may alternately be
programmed as an "access inhibit" input for use with an external access
timer or service switch to prevent access from being granted with Relay
Channel "A".

1A.To use the door sense feature to detect forced entry or door ajar
conditions, install a normally closed door switch on the door or
pedestrian gate and route two wires from the switch to the AD-
500.
1B. To use the door sensing input as an access inhibit input, install
external timer or service switch with a normally open output and
route two wires from it to the AD-500.
2. Connect the sensing wires to the DS-A and GND terminals.
!
NOTE: To program the sensing input as access inhibit, refer to
the Sensing Input Function (PPN #54) step in the System Options
section of these instructions.
