Installing the SP-41R
The SP-41R can be installed in a double-gang
electrical box with a Decora®-style faceplate.
Connecting Multi le Remote
Controls
Up to ten remote controls can be connected
to the SP1200/SP2400 REMOTE bus. The
maximum length of the cable depends on the
type of cable used and the number of remote
controls used in the system.
As a general rule, using 22 gauge wire (at
0.014 Ω/ft. and 34 pF/ft.), one remote can
be up to 3000 feet away, five remotes can be
up to 2000 feet away, and ten remotes can be
up to 750 feet away before transmission
losses become a factor.
