1.2 Install By-Pass Board for “Telephone Mode” Configurations
The 1812’s by-pass board provides a method to by-pass the 1812 and route the incoming telephone line directly to the
homeowner’s phone. The By-Pass board IS NOT optional when using an incoming telephone line or internet (Telephone
Mode) – it must be installed as part of the 1812 system. All telephone wires for the 1812 must pass through the by-pass
board. Wire the by-pass board either for a “Single 1812 - telephone mode” pages 14-15 or “Multiple 1812s - telephone mode”
page 16.
Mount the by-pass board in a location that is easily accessible by the homeowner. In case of 1812 trouble or maintenance, the
homeowner will use the by-pass switch on the board to route the incoming telephone line directly to their home phone. If the
by-pass board is installed outdoors, it must be installed in a NEMA Type 4 enclosure (not supplied) to protect the board from
direct exposure to landscape sprinklers, rain, snow and other elements.
National Electrical Manufacturers’ Association (NEMA) - Type 4 - Enclosure constructed
for outdoor use to provide a degree of protection to personnel against incidental contact
with the enclosed equipment: to provide a degree of protection against falling dirt, rain, sleet,
snow, windblown dust, splashing water, and that will be undamaged by the external formation of ice
on the enclosure.
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. It is recommended
to run all necessary wires to the by-pass board in a “dedicated” telephone wire
conduit. Check the phone wire chart on next page for wire size and distances.
By-pass board MUST be
properly grounded.
Minimum 12 AWG wire
(Not supplied).
Four (4) mounting
screws supplied.
“Entry” switch position:
Routes incoming phone line through
1812 and then to the home phone.
