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.
