SECTION 2 – WIRING & ADJUSTMENTS

Prior to installing wiring to the telephone entry 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 telephone entry 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

National Electric and local building codes.

WARNING! If this telephone entry system is used to control a vehicular gate

with an automatic gate operator, the telephone entry system 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 entry system and touch the

gate or gate operator at the same time. If this unit has not been installed in

compliance with these instructions, do not proceed with any wiring until the

unit has been moved and re-installed in accordance with these instructions.

Use only the supplied transformers (or U.L. listed equivalent) to power the telephone entry

system (16.5 VAC, 20 VA, 60 Cycle). Do not connect the power transformer to a receptacle

controlled by a switch.

Do not power any other devices (electric strikes, magnetic locks, etc.) from this power transformer.

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 telephone entry 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.

Proper grounding of this system is a requirement. The use of surge suppressers can significantly

reduce the chance of component failure because of static charges or surges. To be effective, ground

connections should be made with a minimum 12 AWG, 600 volt insulated wire to a ground point

within 10 feet of the telephone entry system. The ground point must be at an electrical panel, a

metallic cold water pipe that runs in the earth, or a grounding rod driven at least ten (10) feet into the

soil.

16 VAC POWER

Be sure that you use proper wire that has an insulation rated for an underground environment. All

wires should be placed in conduits. Proper pre-planning can greatly ease the installation and wiring

of this system. Always check with the local building code to determine the type of wire required in

your municipality.

The Telephone Entry System is shipped with a Ferrite Filter that must

be installed on the 16 VAC power wires to the main circuit board

(terminals 13-14) to eliminate noise. To install the ferrite filter, simply

snap the filter open, place the wires in the circular core, then snap the

filter closed.
