Installation Instructions

Product Summary

The Sentrol/ITI ShatterPro™ omnidirectional glass-break
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.

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.

Installation Guidelines

❑ For best detection, avoid installing in rooms with

lined, insulating, or sound deadening drapes or rooms
with closed wooden window shutters inside.

❑ Don’t use near an air compressor . A blast of

compressed air may cause a false alarm.

❑ A void 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.

Note

For glass break protection in these applications
(where Shatterpro is not appropriate), use shock
sensors on the windows or window frames.

❑ A void 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.

Note

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.

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.

Pattern Recognition Technology™ of the ShatterPro
ignores most false alarm sounds, including glass-break
testers, so the ShatterPro must be set to “test mode” during

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.
