3.8 General Wiring Information

The wiring of the tracker board(s) is an extremely important and integral part of the overall

access control system. Use proper wire for weigand and power wire runs, and be sure that

the system is properly grounded. Check all local building ordinances and building codes

prior to installing the system. Be sure that your installation is in compliance with these codes.

• Use only the supplied power transformers (16 VAC, 20 VA) or U.L. listed equivalent to power

the tracker board. You may power up to four (4) tracker boards from a single 16 VAC, 40 VA

power transformer.

• Use 18 AWG wire for power wire runs up to 100 feet. Use 16 AWG wire for power wire runs

up to 200 feet. It is advisable to keep power wire runs as short as possible.

• Do not power any other devices (electric strikes, magnetic locks) from the tracker board

power transformer. These devices must be powered from their own power supply.

• Proper grounding of the system is required. To be effective, ground connections should be

made with a minimum 12 AWG wire with a ground point within 10-feet of the access control

system. The ground point must be an electrical panel ground buss, a metallic cold water pipe

that runs in the earth, or a grounding rod driven at least 10-feet into the soil. If there are

several components in the access control system within close proximity to each other, you

should consider using a single-point ground system. Check with your building department for

specific grounding guidelines as soil conditions and grounding requirements differ depending

on your geographical location.

• Surge suppressers can significantly reduce the chance of component failure because of static

charges or surges. We recommend using both high and low voltage surge suppressers to

help protect equipment from damage. High voltage suppresser P/N 1876-010; low voltage

suppresser P/N 1878-010.

• A 12 VDC, 3 amp-hour battery (P/N 1801-009) can be used to supply backup power to four

(4) tracker boards. Use a 12 VDC, .8 amp-hour battery (P/N 1801-007) to backup a single

tracker board. Battery backup power is optional and not required for normal tracker board

operation.

• Be sure to color code all wires.

WARNING! If the access control system is used to control a vehicular gate

with an automatic gate operator, the access control device must be mounted

a minimum of ten (10) feet away from the gate and gate operator, or in such a

way that a person cannot operate the access control device and touch the

gate or gate operator at the same time.
