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.
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.

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.
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.
❑
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.
Note
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.
