Be sure to properly
ground ALL boards.
See previous page
for acceptable
grounding sources.
TIP (+): White/blue mark
RING (-): Blue/white mark
Magnetic locks or electric strikes must be
powered from a separate UL Listed power
transformer. DO NOT power strikes or magnetic
locks from the 1812 power transformer. Use
minimum 18 AWG wire for runs up to 100 feet;
16 AWG wire for runs up to 200 feet. It is
recommended to keep power wire runs as short
as possible.
By-Pass Board
The By-Pass board is NOT optional and
must be installed as part of the 1812
“Telephone Mode” system.
See page 11 for complete information.
Single 1812:
PHONE IN #3 connects to Main Term #1.
PHONE IN #4 connects to Main Term #2.
PHONE OUT #5 connects to Main Term #5.
PHONE OUT #6 connects to Main Term #4.
Phone Line Surge Suppressor
DoorKing Surge Suppressor
P/N 1877-010 (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.
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.
Separate UL
Listed Power
Transformer
Connect to Incoming Telephone
Company’s Phone Line
Locate the telephone company demarcation device.
IMPORTANT
Identify the wires that connect to the
homeowner’s telephone. Disconnect these 2 wires from
the demarcation device and connect them to terminals
#7 and #8 HOME on the by-pass board.
Connect a new twisted-pair telephone wire to the
telephone company demarcation device where the 2
wires were just removed from. Connect the other end of
the new twisted-pair wire to CENTRAL OFFICE terminals
#1 and #2 on the by-pass board (Unless using a surge
suppressor, then wire to surge board first).
Place the by-pass switch in the “By-Pass” position until
the 1812 installation is complete. Test the homeowner’s
telephone. It should have a dial tone while the switch is
in the “By-Pass” position. See page 11.
Check Polarity of
Telephone Line
Check for polarity on the
incoming telephone line to each
board and maintain polarity
throughout the telephone line.
One potential problem checked
when a malfunction occurs in a
telephone entry system is to
see if the telephone line has
been wired to each board with
the correct polarity.
Test Example: By-pass board’s
CENTRAL OFFICE terminals #1
and #2. Terminal #2 must be
positive (Tip +) with respect to
terminal #1 (Ring -). Set a VOM
meter to measure DC volts.
Place the positive lead on
terminal #2 and the negative
lead on terminal #1. If the
meter shows a positive voltage
- OK. If the meter shows a
negative voltage (needle moves
off scale to the left), reverse the
wires on terminals #1 and #2.

The 1812 Classic operates ONLY on
24 VAC. Use the supplied power
transformer, 24 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 previous page for wire size
and run distances.
