SECTION 5 - MAINTENANCE

The DoorKing Access Plus 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 access codes on an as needed basis.
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.
Creating Printed Directories for 1808 or 1810 units:
The Access Plus Account Manager software will print a directory for either the 1810 Access Plus or the 1808 Access Plus. The
directory can then be easily inserted into the respective unit.

5.1 Troubleshooting

If problems should develop with your Access Plus system, refer to section 5.3 troubleshooting table to try and correct any
problems. Our experience has shown that a majority of reported problems are actually programming 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. Check the polarity of the phone lines. See section 5.2 on the next page.
4. Be sure that the entry system case is properly grounded.
5. Be sure that the telephone wires are twisted.
6. A hum on the system indicates that the phone line or 16.5 VAC power lines may be grounded. Check to be sure that the
phone lines or power lines are not shorted to ground. Be sure that the cable used for communication is a twisted pair, good
quality phone cable insulated for direct underground burial. Using phone wire that is designed for indoor use only can absorb
moisture and cause a hum on your phone line.
7. Check the 16.5 VAC system power. Be sure that the transformer is properly rated (20 VA). DO NOT USE 24 VAC POWER.
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!
