Up to five (5) 1812s may be
wired in series using the method
shown: 1st 1812’s PHONE IN to
2nd 1812’s PHONE OUT; 2nd
1812’s PHONE IN to 3rd 1812’s
PHONE OUT, etc.
Each 1812 must have a unique
ATTENTION NUMBER (See 2.4.3)
and a unique MASTER CODE (See
2.1).
The 1812 that is the furthest away
from the phone or PBX / KSU
system must be programmed for
INTERCOM MODE. All other 1812
units in the series are
programmed for TELEPHONE
MODE (See 2.4.1).
Be sure to properly ground ALL
1812s. See page 13 for
acceptable grounding sources.

Telephone Line
For complete information,
see page 12.
Check Polarity of Telephone Line
Check for polarity on the incoming telephone line to
each 1812 board and maintain polarity throughout
the telephone line to the homeowner’s phone. 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: 1st 1812 board’s PHONE IN
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.
