Installing Vp Series Keypads - PTI VP Installation And Operation Manual

Installing VP Series Keypads

Power and data communication wiring are the most important
wiring component for VP devices. A VP requires power and
communication lines connected to the controller.
The system will not operate properly if the voltage is below
12VDC. Extreme care should be taken when choosing a power
supply voltage and current rating. Long distance runs may require
a remote power supply to be installed in line with an RB5 relay to
ensure proper operation
PTI recommends that power and data communication be run
through a single 18 AWG, 4-conductor shielded cable. Some
installations will require larger gauge wire. See "Drawing 5: Wiring
for VP keypad" on page 8 for details on connecting the wiring
to the VP device.
With the RS485 communication scheme, a keypad can be located
as far as 4000 feet from the controller, therefore shielded twisted
pair cable with ground wire is required for optimal operation.
Additionally, larger gauge wire must be used the farther the
device is from the controller.
Additional cables may be needed for the intercom, gate operator,
door strike, presence detector, or other device.
• Use approved electrical conduit to supply the wiring to the VP.
• Local building codes determine the actual installation
techniques and wiring methods.
• Only licensed contractors should install VP devices.
• Correct installation methods are critical for a trouble-free
keypad. Most of the problems that emerge during use can be
traced back to poor installation techniques or improper wiring.
All installations must conform to local building and electrical
codes. When discrepancies exist between local codes and this
manual, local code takes precedence.
