filled bollards to prevent vehicles from damaging the keypad.
• There are several different styles of gooseneck stands available.
Single Bollard
• A bollard is an attractive and functional stand for keypads. It helps protect the keypad
from vehicle damage. It can be used in driveways for vehicle access or near doors as
a keypad stand. Height is determined by the length of the pipe on
which it is mounted.
• Bollards are usually filled with concrete and used as the barrier to
protect the keypads.
• Both single and double bollards are mounted on a schedule 40 10-
3/4" diameter pipe with a .365" wall. This pipe is footed in concrete
an dfilled ¾ of the way with concrete to create a solid barrier.
PTI recommends that power and data communication be run through
a single 18AWG, 4-conductor shielded cable.
Some installations will require larger gauge wire.
With the RS485 communication scheme, the keypad can be located
as fas as 4000 feet from the controller, therefor shielded twisted pair cable with ground
wire is required for optimal operation. Additionally, larger gauge wire must be used the
further from the controller the device is.
Additional Cables may be needed for the gate operator, door strike, presence detector, or
other devices.
• Use approved electrical conduit to supply the wiring to the keypad.
• Local building codes determine the actual installation techniques and wiring methods.
• Only licensed contrators should install these 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.
