The DoorKing telephone entry system is essentially a maintenance free device. When the unit is properly installed, it should
provide years of trouble free service. Maintenance is limited to updating the directory and phone number and/or entry codes
when residents move in or out.
The faceplate of the unit should be cleaned on a regular basis to keep contaminants in the air from sticking to the surface and
possibly causing pitting. When cleaning the faceplate of the system, NEVER use an abrasive cleaner or cloth. Stainless steel
cleaner works very well with a soft cloth for systems with a stainless steel faceplate. A clean damp soft cloth should be used to
clean gold plated faceplates.

5.2 Troubleshooting
If problems should develop with your telephone entry system, refer to the troubleshooting table below and on the following
pages to try and correct any problems. Our experience has shown that a majority of reported problems are actually program-
ming related and can be corrected on site. If problems persist and they cannot be corrected, contact your authorized DoorKing
dealer for assistance. Before performing any troubleshooting, check the following:
1. Have a good VOM meter handy to check voltages and continuity.
2. Have a telephone test set (DoorKing P/N 1800-050 or equivalent) to check the telephone line. Noise on the phone line will
cause problems with the entry system.
3. Be sure that the entry system case is properly grounded.
4. Be sure that the telephone wires are twisted.
5. A hum on the system indicates that the phone line or 16 VAC power lines may be grounded. Check to be sure that the phone
lines or power lines are not shorted to ground.
6. Check the 16 VAC system power. Be sure that the transformer is properly rated (16 VAC, 20 VA). Keep the wire run from the
transformer to the entry system as short as possible. Use 16 or 18 AWG, 600 volt insulated wire only. The importance of
proper power wiring cannot be over stressed!
7. Isolate the telephone entry system. Disconnect any external devices, such as gate operators, electric strikes, magnetic locks,
etc., which may affect the operation of the system.
