Controlled Products Systems Group AK-11 - Manual (Page 4)

INSTALLATION
To avoid damage to the unit from static discharges, connect the
EARTH GROUND terminal to a good earth grounding point.
Suggested wiring size is 18 AWG for earth ground and power (up
to 500 feet of 18 AWG wire can be run for power, use larger wire
for longer runs). Use 22 AWG or larger (depending on the load)
for all other connections.
! CAUTION: If the unit is AC powered, and one side of the
power transformer secondary is connected to earth
ground, connect the grounded side to the “-” power
terminal of the unit.
Select a location for the keypad. For door access control
installations, mount the keypad near the controlled door. For gate
control installations, mount the keypad in clear view of the gate,
but far enough from the gate so the user cannot touch the gate
from the keypad.
# WARNING: TO AVOID SERIOUS INJURY OR DEATH, MAKE
SURE THAT THE UNIT IS FAR ENOUGH FROM THE GATE
SO THAT THE USER CANNOT TOUCH THE GATE WHILE
OPERATING THE KEYPAD. HOWEVER, THE GATE MUST
BE FULLY VISIBLE FROM THE KEYPAD.
Pedestal Mounting
The AK-11 keypad can be mounted on a standard pedestal.
Use four security bolts and locking nuts to secure the
keypad’s backplate to the pedestal (see Figure 3).
Wall Mounting
The AK-11 keypad can be mounted directly to a wall or flat
surface.
Use the appropriate fasteners to secure the keypad’s
backplate to the mounting surface.
When mounting the keypad to a concrete wall, use
concrete wedge anchors or molly anchors (see Figure 4).
