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.
