Chapter 3: Entrance Keypad Installation
Entrance Keypad Mounting
„
The Entrance Keypad should be mounted securely to the wall of the car wash, in the
entrance to the tunnel, at approximately chest height.
„
The Entrance Keypad is a Type 3 enclosure, which means it is a watertight enclosure, but
should not be mounted where it is constantly inundated with water.
„
The Entrance Keypad should be mounted away from corrosive chemicals.
Entrance Keypad Wiring
„
Locate conduit that was run from the Tunnel Master® Jr. relay box.
„
The conduit shall be secured with a Listed watertight conduit hub, and should be
tightened to the torque specs of the manufacturer. Over torquing may cause enclosure
breakage.
„
The conduit will contain the 12 VAC and Communications cable and should enter the
opening in the bottom of the keypad enclosure.
„
Electrician must run 3 - 18 AWG wires, or cable (supplied by the electrician) through the
3/4” conduit from the Tunnel Master Jr. to the Entrance Keypad.

„
There is a terminal block (POWER), located on the keypad circuit board labeled with
ACH
for line,
ACN
for neutral, and
GND
for Ground. Terminations for the 3 – 18AWG wires should be torqued
to 20 pound-inches (2.3 n-m.) Over torquing may cause enclosure breakage.
„
The Tunnel Master Jr. is equipped with a 12 VAC transformer, which is to be used to power the
Entrance Keypad. If a second transformer is present, the 12 VAC terminations must be made as in
Figure 3-2 from the separate transformer. If there is only one transformer, terminate power from
it.
„
Electrician must run a single-twisted pair, 24AWG shielded COMM cable (can be purchased from
ICS) through 3/4” conduit from the 485 terminal to the Entrance Keypad.
