SECIION 2: INSTALLATION
This sectiw is divided into three parts:

23 POWER
The 810B reqb 14 volts AC or 18 volts DC. A
wall
mounted power module with an output of 14 volts AC at
1.6 amps= is shipped with each unit. An ex& supply
or trausf~mer capable of supplying this power may Plso be
used. Attach the output of the AC supply to pins 2 md 3
of JlOl on the rear panel. (See Figure 3-2, Outline
'
Drawing Rear Panel.) If n DC supply is used, mnaect the
positive side of the supply to pin 2 md the negative side of
the supply
to pin 4 of J101.
2.2.1 Wm and Cable ComiWom
The Model 810B is ranntaed to other units within a
system using SO-conductor, (25pir) cables, similar to
those used by the telephme company.
The cables may be
up to 10,000 feet long.
These cables are available from
RTS sy*, nfcr to Model 4015-XX (-XX refels to
cable lea$(h md type) in flat ribbon cable or nnmd twisted
pir cable (strpnded).
All of the Model 810B dgnratim nquire that the
