PREPARATION
SELECTING A LOCATION
For your security system to be most ef-
fective, you need to install it in a location
that meets all of the following condi-
tions:
• Is near an AC outlet.
Note: If your best location is not
near an AC outlet, you can have an
electrician install an outlet for you.
• Is near a modular telephone jack.
Note: If your best location is not
near a modular telephone jack, you
can install a modular jack yourself
or have the telephone company
install one for you.
– Radio Shack stores sell jacks,
adapters, and telephone wiring.
– The telephone company charges
to install the necessary jacks.
– The USOC number of the jack to
be installed is RJ-11C (or RJ-
11W for a wall plate jack).
• Overlooks an area that an intruder
would most likely cross when
entering or moving through your
home.
You can place the system on a
shelf or table, or mount it on a wall
or in the corner of a room. The sys-
tem detects movement by sensing
a change in temperature within its
field of view. When someone walks
past the system, it detects the tem-
perature change and triggers the
alarm.
Also, note that the system is more
sensitive to movement across its
coverage area than to movement
directly toward or away from it.
