Detail Drawings

• External time clock input may be used to create an additional time zone for entry codes.

• Two 12 volt, .8 amp gel-cell batteries (DoorKing p/n 1801-008 or equivalent) can be

connected in series to provide 24 volt DC power to operate the system or keep the system

running in the event of a power outage.

• Back-up batteries are not required to keep the internal time clock in the 1812 system running.

This clock has its own built-in standby power source.

• Relay contacts are rated for 3 amps @ 30 VAC maximum.

• It is highly recommended that a low voltage surge suppresser (DoorKing p/n 1878-010) be

installed to help protect the telephone entry system from power surges.
