Installation
Use the following procedure to install the ShatterPro.
1. Choose a mounting location. Since the sound of
breaking glass travels straight out from the broken
window, the best location for mounting the sensor is
the wall opposite the window--assuming the glass to
be protected is within the sensor range and line of
sight. The ceiling and adjoining (side) walls are also
good sensor locations. A ceiling mounted sensor will
have better detection if located 6-10’ (2-3 m) back
from the glass rather than directly above the glass.
Important !
DO NOT EXCEED THE 20’ MAXIMUM
DETECTION RANGE OF THE SHATTERPRO.
While the sensor may function beyond the 20’
range, it could miss a minimum output glassbreak.
Furthermore, changing conditions in the room, such
as rearranging furniture, could reduce the range of
the sensor back to 20’.
2. Remove the cover from the ShatterPro base. Hold the
base against the wall or ceiling at the desired mounting
location. Insert screws through the two mounting holes
in the base to attach it to the mounting surface.
CAUTION
You must be free of all static electricity before
handling the transmitter circuit board. Touch a
grounded, bare metal surface before touching the
circuit board, or wear a grounding strap.

3. Insert two 3V batteries as shown in Figure 4 and
replace the cover.
4 Use the procedures in the following sections, “Testing
the ShatterPro” and “Testing the System,” to make
sure the sensor is working properly with the panel.

Testing the ShatterPro
Pattern Recognition Technology™ of the ShatterPro
ignores most false alarm sounds, including glassbreak
testers, so the ShatterPro must be set to “test mode” during
Figure 5. Testing the ShatterPro
the following procedure (see step 2). When the sensor is in
test mode, processing of the glassbreak pattern in the
upper and lower frequencies is disabled. The ShatterPro is
then listening only for the mid-range frequencies, which
the tester reproduces. It is these frequencies that determine
the sensor detection range.
