Installation Instructions
Product Summary
The ShatterPro® omnidirectional glassbreak sensor
provides 360 degree coverage. It can be mounted on the
ceiling, or on the opposite wall, or on adjoining walls. It
has a range of up to 20 feet for glass panes 1 x 2 (0.3m x
0.6 m) or larger.

Figure 1. The ShatterPro Glass Break Sensor
The maximum detection range is 20 (6 m) for plate,
tempered, laminated and wired glass. For armor-coated
glass, the maximum detection range is 12 (3.65 m).
Coverage is measured from the sensor to the point on the
glass farthest from the sensor (see D and D in Figure 2).
See Specifications for recommended glass thickness.

ShatterPro may not consistently detect cracks in
glass, or bullets that break through the glass.
Glassbreak sensors should always be backed up
by interior protection.

Installation Guidelines
❑ For best detection, avoid installing in rooms with
lined, insulating, or sound deadening drapes or rooms
with closed wooden window shutters inside.
❑ Dont use near an air compressor. A blast of
compressed air may cause a false alarm.
❑ Avoid stairwells, glass booths, and all rooms smaller
that 10 x 10 (3 m x 3 m).
❑ The Pattern Recognition Technology of the
ShatterPro ignores most false alarm sounds. Some
sounds can duplicate the glass break pattern the
ShatterPro detects, however, so the ShatterPro works
best in rooms with only moderate noise. Avoid rooms
where white noise, such as a fan, is present. Avoid
rooms with noisy areas or multiple noise sources such
as small kitchens or bathrooms, garages, etc.
Not
For glass break protection in these applications
(where ShatterPro is not appropriate), use shock
sensors on the windows or window frames.
❑ Avoid adding (learning) the sensor into 24-hour sensor
groups, where the sensor will be armed even when the
room is in use. Like a motion detector, a glass break
sensor may be tripped when occupants are in the
protected area. Adding the ShatterPro to a perimeter
sensor group, which is armed only when the perimeter
doors and windows are armed, will help prevent false
alarms.
❑ Do not install in humid rooms. The ShatterPro is not
hermetically sealed. Excess moisture on the circuit
board can eventually cause an electrical short and
possibly a false alarm.
❑ The sensor can be mounted as close as 3.3 (1 m) from
the glass.
Tools Needed
❑ Phillips screwdriver
❑ Sentrol 5709C hand-held tester
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.
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.
