1812 Plus – single system.

Basic wire connections.

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.

Mount the by-pass switch in a location that is easily accessible by the homeowner. The By-

Pass switch IS NOT optional – it must be installed as part of the 1812 system. If

installed outdoors, be sure to protect the by-pass switch from direct exposure to rain, snow

and other elements.

Locate 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.

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. Check the power wire chart for

wire size / distance.

Be sure to properly ground all devices. Minimum 12 AWG wire.
