ENTRANCE KEYPAD MOUNTING AND 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 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 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 customer)
through the 3/4” conduit from the e to the Entrance Keypad.
