SECTION 2 – WIRING
Prior to installing wiring to the access control system, we suggest that you become familiar with the
instructions, illustrations, and wiring guidelines in this manual. This will help insure that you
installation is performed in an efficient and professional manner.
The wiring of the access control panel is an extremely important and integral part of the
overall access control system. Use proper wire for the communication line, power wires, and
be sure that the system is properly grounded. Check all local building ordinances and
building codes prior to installing this system. Be sure your installation is in compliance with
local codes.
WARNING: If this access control system is used to control a vehicular gate with an automatic
gate operator, the access devices (card reader, keypad, etc.) must be mounted a minimum of
ten (10) feet away from the gate and gate operator, or in such a way that the user cannot come
into contact with the gate or gate operator when using the entry device. If the entry device
has been installed closer to the automated vehicular gate, do not proceed with any wiring until
the device has been moved and re-installed so that it is in compliance with these instructions.
Use only the supplied transformers (or U.L. listed equivalent) to power the access control system and
any wiegand input devices (16.5 VAC, 20 VA). Do not power any other devices (electric strikes,
magnetic locks, etc.) from these power transformers. For wire runs up to 100 feet, use 18 AWG, 600
volt insulated wire. For wire runs up to 200 feet, use 16 AWG, 600 volt insulated wire. Power wires
are susceptible to noise and hum pickup; therefore it is preferable that you keep power wire runs as
short as possible.
This access control system contains a number of static sensitive components that can be damaged or
destroyed by static discharges during installation or use. Discharge any static prior to removing the
circuit board from the lobby panel by touching a proper ground device.
If Tracker expansion boards are being used with this system, refer to the Tracker Installation and
Wiring manual that came with the Tracker expansion boards, for detailed information on wiring
Tracker boards to the PC programmable access control system.
If Elevator Control is used with this system, refer to the Elevator Control Installation and Wiring
manual for detailed information on wiring the elevator control boards to this system and to the
elevator push button control panel.
