MOUNTING THE ALARM
Your alarm is designed for mounting on
non-metallic doors and windows only. It
uses a magnet to trigger the internal alarm.
Mounting on metal surfaces can interfere
with proper operation of the magnetic sen-
sor.
Selecting a Location
For proper alignment, you must mount the
alarm and magnet so the magnet rests
with its arrow pointing toward the alarm’s
engraved line. Choose a location that lets
you install the magnet on a door or window
and the alarm immediately next to it on the
frame, or vice versa. The distance be-
tween the alarm and magnet must be no
more than
1 / 3 inch (8 mm).
