For best false alarm immunity:
•
Avoid 24-hour loop applications (perimeter loop OK).
•
Don't use where white noise such as air compressor noise
is present. (May cause false alarms by saturating the
glass break frequency spectrum).
•
Avoid rooms smaller than 10 ft. x 10 ft. (3.0 m x 3.0 m)
and rooms with multiple sounds such as small kitchens,
glass booths, noisy areas, garage, small bathrooms, etc.
•
Sensor should also not be used in rooms where noise
causes the sensor's LED to frequently flash, if the same
noises will be present when the sensor is armed.
Mounting location
For best false alarm immunity the sensor should be located at
least 4 ft. (1.0 m) away from noise sources (televisions,
speakers, sinks, doors, etc.). The sensor must always be in
direct line of sight of all of the windows to be protected. It
cannot consistently detect glass breaking around corners, in
other rooms, etc.
Important:
Do not mount in corners or wall-ceiling
intersections.
Wall Mounting
Since the sound of breaking glass travels directionally out from
the broken window, the best location for mounting the sensor is
on the opposite wall, assuming that the wall is within the
sensor's range and line of sight to the protected glass. The
ceiling or an adjoining (side) walls are also good sensor
locations, assuming that they are mounted within range and
line of sight to the protected glass.
As with all glassbreak sensors,
same wall mounting, since such detection is partially
dependent on glass break sound reflection off the opposite
wall. With same wall mounting, test range with the 5709C
tester held flat against the glass. Depending on room
acoustics, there may be a reduction in range.
Ceiling mounting
Mount the sensor on any type of ceiling in a location which is in
direct line of sight of the windows to be protected. The sensor
can be mounted as close as 3.3 ft. (1 m) from the glass. Since
the sound of glass break travels directionally out from the
broken window, however, a ceiling mounted sensor 8 ft.
(2.0 m) into the room may detect better than a sensor mounted
close to the glass.
Prior to final installation of the ShatterPro II, the sensor should
be pre-tested in the desired location to confirm coverage. To
test range, a 5709C hand-held tester is required. This is the
only tester which accurately verifies range of the sensor.
Temporarily mount the sensor
1.
Connect a 9 V battery to ShatterPro II for testing
purposes.
2.
Use the double-stick tape provided to mount the sensor in
the desired location.
3.
Use the 5709C hand-held tester to set the sensor into test
mode. Set the tester to tempered glass and hold the tester
on top of the sensor. Activate the tester. The sensor will
then trip into alarm and go into test mode for one minute.
When in test mode the sensor's LED will blink
continuously. Extend the test time by firing the tester at the
sensor at least once a minute.

See Figure 2.
1.
Holding the tester near the surface of the glass,
tester at ShatterPro II
drapes or blinds are present, test with the hand-held tester
behind the closed drapes or blinds (do not use sensor with
heavy or lined drapes). If mounted on same wall, point the
tester at opposite wall.
2.
The 5709C tester has different settings for each type of
glass. The tester should always be set for tempered or
laminated glass (either is correct and both have the same
range) unless the installer is certain that all the glass to be
protected is plate glass, in which case the plate setting
may be used.
If the LED on the sensor goes solid for four seconds when the
tester is triggered, the glass is within detection range.
If the LED does not go solid, but simply continues blinking as
before, reposition the sensor closer to the protected windows
and retest. This may require adding additional sensors in order
to achieve adequate coverage. It is very rare that the sensor
will not activate within its stated range of coverage. Double-
check adequate battery strength in the hand-held tester. A new
tester battery will likely restore range.
IMPORTANT:
Room acoustics can artificially extend the range
of a glassbreak sensor. The specified range of ShatterPro II
has been established for worst-case conditions. While the
sensor will likely function at additional range, it may miss a
minimum output break, or room acoustics may be changed at
some future time, bringing sensor range back into normal
conditions.
Caution:
Do not exceed the rated range of the sensor,
regardless of what the tester shows.
How test mode works
The Pattern Recognition Technology™ of ShatterPro II ignores
false alarm sounds, including hand-held glassbreak testers. In
order to test ShatterPro II, a test mode is used. With the sensor
in test mode, portions of the glass break pattern processing are
disabled. ShatterPro II is then listening only for those
frequencies which determine sensor range, as reproduced by
the 5709C tester.
Checking the sensor
ShatterPro II can be checked by the installer or end-user while
in normal mode, simply by clapping hands loudly under the
sensor. The LED will blink twice, but the sensor will not trip.
This verifies visually that the microphone and circuit board are
functioning.
In normal mode, ShatterPro II will not trip to the tester, unless
the tester is held on top of the sensor.
When ShatterPro II trips to an alarm condition, it will light solid
for four seconds, then go into test mode, blinking for one
minute. At the end of one minute the LED will extinguish in
"Set-up LED" mode, or the LED will light if set for "Latching
LED" (open J3 for latching LED).
Installation tips
•
ShatterPro II is designed to detect the shattering of framed
glass mounted in an outside wall. "Testing" the sensor with
unframed glass, broken bottles, etc. may not trip the
aim the
and hold down the test button. If
