Be sure to properly ground the 1812. See
page 13 for acceptable grounding sources.
Be sure to properly ground the
surge suppressor. See page 13 for
acceptable grounding sources.
Low Voltage Surge Suppressor
DoorKing Surge Suppressor P/N 1878-010 (or
equivalent) is optional but highly recommended.
For best protection, surge suppressor ground wire
MUST be 3-ft. or less in length. Use minimum 12 AWG
wire. Refer to instruction sheet included with surge
board for complete information.
Connect to Homeowner’s Telephone
When connecting directly to a single telephone or an
un-used C.O. port on a PBX or KSU system, use the
PHONE OUT terminals only in the 1812. It must be
programmed for INTERCOM mode using this
configuration.
When the 1812 is programmed for intercom mode, it
provides the constant source of DC voltage necessary
for communication. The intercom mode also
disconnects the “PHONE IN” terminals (1 and 2)
since they are not used.
Be sure that the 1812 is programmed in the intercom
mode.

The 1812 Plus operates ONLY on 16.5 VAC.
DO NOT power the 1812 with 24 Volt
transformer or source voltage. Use the
supplied power transformer, 16.5 VAC, 20
VA (or UL listed equivalent) to power the
telephone entry system. DO NOT power any
other devices (electric strikes, magnetic
locks, additional 1812s etc.) from the 1812’s
power transformer. See page 13 for wire
size and run distances.
