• Does not directly face a window,
heating or air conditioning vent,
appliance, outside wall, or other
heat source.
These sources could produce rapid
temperature changes that the sys-
tem might incorrectly identify as an
intruder.
Is high enough not to be triggered
by pets, yet is low enough to be
triggered by someone of average
height walking across the area.
To help prevent false alarms
caused by pets, the system senses
motion at or above its mounted
location. It does not sense motion
below where you mount it. In most
installations, a location about 3
1
/
2
feet off the floor provides the best
security.
TESTING THE LOCATION
Once you select a location and before
you mount it, follow these steps to test
the system’s coverage.
Note:
To test the location, you do not
need to connect the system to the
phone line, install a backup battery, or
set up service.
1. Plug the power adapter’s barrel
plug into the jack on the back of the
system as shown on Page 10.
2. Plug the power adapter into an AC
outlet as shown on Page 10.
Notes:
If you have not installed a
backup battery, the POWER
indicator flashes.
If you have not connected the
system to the phone line, the
system chirps once per second.
3. Place the system at the selected
location. If you selected a location
on a wall, place the system on a
stepladder or something similar to
position it as close as possible to
its final mounting location.
4. Walk around the area you want to
protect. When the system detects
your movement, its ARMED indica-
tor flashes.
5. Adjust the system’s position until
you are satisfied with its coverage.
