Following are instructions on installing a VP series keypad and connecting
the wiring run from the system controller:
1. Open the device by removing the four stainless steel button head
machine screws on the front of the keypad case using the security
hex key provided with the unit. The front and back half will separate.
2. Mount the back plate to the
desired keypad location using the
three-keyed holes. Seal around
the back of each screwhole and
around the back of the wire hole
with an outdoor silicone sealant. If
the keypad is being mounted on a
gooseneck or bollard, run a bead
of silicone in a triangle around the
three screwholes. If the keypad is
being mounted on a wall, before
mounting, run a bead of silicone
in a square around the back of the
keypad about ½ inch from the edge.
3. Pull the necessary wires through the wire hole on the back of
the housing. Allow an extra 1 foot of wire to remain inside the
housing. After the wire connections are complete, excess wire can
be pushed back into the gooseneck or wall or it can be carefully
positioned inside the keypad housing for future maintenance and
service. Each keypad should have the following wires:
• One 18 AWG, 4-conductor, shielded cable coming in from the
controller or from the previous AI device in line.
• One 18 AWG, 4-conductor, shielded cable going out to the next AI
device in line (if there is another AI device down the line).
• One earth ground wire
• One or two 18 AWG, 2-conductor cable(s) coming from the gate
operator or door strike.*
• One 18 AWG, 2-conductor, shielded cable coming from the
intercom base station if intercoms are being used.
• One RG59U video cable if a pinhole camera is being used.
• One 18 AWG, 2-conductor cable for the presence sensor if it is
being used.
* The cable to the door strike or gate operator will only be present if the relay inside
the particular keypad is being used to trigger the door or gate. The controller can
be configured to use relays on the circuit board, on a separate relay board, or
on almost any other AI device to trigger a gate or door. For security reasons, the
relay in the keypad nearest a door or gate should not be the one used to directly
trigger the gate or door.
