ALocate the telephone company demarcation device.
IMPORTANT! Identify the wires that connect to the
homeowner’s telephones. Disconnect these wires from
the demarcation device and connect them to terminals 7
and 8 on the by-pass switch.
Connect a twisted-pair telephone wire to terminals 1 and 2
on the by-pass switch. Connect the other end of these
wires to the telephone company demarcation device where
you removed the wires from above.
Place the by-pass switch in the “BY-PASS” position until
the 1812 unit is installed. Test the homeowner’s telephone.
They should have dial tone while the switch is in the BY-
PASS position.
Use supplied 16.5 VAC, 20 VA power transformer or UL Listed equivalent. DO NOT
Power this device with a 24 Volt transformer or source voltage.
Use only twisted pair telephone wire that is rated for direct underground burial. DO NOT use
wire that is intended for indoor applications. Recommend Cat5e Gel Filled (flooded)
UV Resistant Direct Burial Cable in conduit. DO NOT run telephone wires and high
voltage wires in the same conduit. Check the phone wire chart for wire size / distance.
Check for polarity on the phone "IN" wires, terminals 1 and 2. Terminal 2 must be positive
with respect to terminal 1. 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.
