2.4.3 Performing a
Secure Installation
In this configuration, the prox.pad plus prox sensor
housing is removed from the keypad/controller and
located a maximum of 10 feet away. The controller/key-
pad is located inside a secure area.
1. Remove the antenna from the prox.pad plus key-
pad/controller as described below:
• Disconnect the backplate of the prox.pad plus unit
from the front keypad/controller.
• When handling the main printed circuit board, to
guard against possible static discharges, touch a
grounded object BEFORE touching the prox.pad
plus unit. Remove the main printed circuit board
by pressing the two spring tabs in the d irection of
the arrows as shown in Figure 2-5. Be careful with
the wires.
• Pull on the main circuit board and remove Pin
connector P4 (a 4-pin connector) from the bottom
of the main board. A ribbon cable now holds the
main board to the keypad board. DO NOT pull
this ribbon cable out of its connector! Once the
main board is r emoved, you can access the interior
of the antenna.
• Remo ve the antenna housing from the key-
pad/controller by pressing the labeled four secure
tabs inward (see Figure 2-5) until the sensor hous-
ing “pops out.”
2. Prepare the wiring and extension wiring as fol-
lows:
• Cut off the plastic end of the prox.pad plus sensor
housing harness.
• Splice the recommended remote antenna cable
Alpha 1174C (22AWG), 10-foot maximum length,
to the properly cut antenna cable using standard
electrical techniques.
