SECTION 2 – WIRING
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
local codes.
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. If this unit has been installed closer to the automated vehicular
gate, do not proceed with any wiring until the unit 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 telephone entry system
(16.5 VAC, 20 VA for 1803PC and 1815, 16.5 VAC, 40 VA for 1817) and any weigand 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 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 stainless steel grounding rod driven at least ten
(10) feet into the soil.
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.
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 telephone entry 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.
