• Gate Operators. Most electric gate operators require a normally
open contact (pins 4 & 5). Some electric door strikes require a
normally closed contact (pins 5 & 6). If door strikes are used it is
recommended that they be 12V DC. A shunting diode must then
be installed across the solenoid to prevent ground spikes from
disrupting the keypad communication. DO NOT PLACE A DIODE
ACROSS AC STRIKES AS IT WILL SHORT OUT THE POWER
SUPPLY FOR THE STRIKE.
11. The presence sensor function of the VP series keypad allows the
keypad to be connected to a loop detector or pressure mat that
requires a ‘presence’ in order to use the keypad. This helps prevent
users from walking up and using the keypad in a driveway area
where they might be in danger from vehicles or the gate. Most
often, this is used in connection with a gate operator and loop
detector. The loop detector wires are spliced into and connected to
terminal block P5 in the keypad. The keypad is programmed with
the Presence Required ‘ON’. See Setup Functions for information
on setting up this feature.
12. After all wiring is complete, gently push the excess wire back
through the hole in the wall or gooseneck, leaving just enough slack
to allow the keypad to be opened for service or maintenance. Seal
the back wire hole with outdoor-rated silicone sealant and then
screw the housing back together.
Warning: Use recommended UL installation. Do not connect a gate operator
or door strike to a keypad that is located outside the area it secures. This will
prevent someone from gaining access to your site through vandalism.
Warning:
Wiring the relay to the operating device will introduce the operating
device control voltage into the keypad housing. The installer must verify that
this is not high voltage! The VP is not designed for the presence of high voltage
within the keypad case. Relay voltage must not exceed 30 volts.
