2.0 Installation Considerations
NOTE: Always pre-test the detector’s location using the DS11 10i
Glass Breakage Tester.
• Do Not…
…Mount the detector with obstructions between the glass being
protected and the detector.
…Mount on the same wall as the glass being protected.
…Mount the detector closer than 5 ft. (1.5 m) to the wall that the
glass being protected is on, or any hard, sound reflecting surface.
…Mount closer than 2 ft. (0.6 m) to heating or cooling outlets;
mount as far away as possible. If drafts from these outlets
blow on the detector, select a different location for the
detector. Use the environmental test (see Section 4) to verify
good installation locations.
…Install on 24-hour protection circuits.
• If you must install the DS1101i, DS1 102i, or DS1 108i in a zone
that is armed when occupied...
…Avoid acoustically live areas such as kitchens and bathrooms.
…Use a delay zone to provide the user time to acknowledge the
false alarms.
…Instruct system users how to respond to a false alarm.
• Remember…
…The best mounting location is 10 to 20 ft. (3 to 6 m) from the
glass, in-line with the glass’s center, and on the ceiling or opposite wall of the glass being protected. Do not exceed maximum
range.
…The detector should be within ±30° of the center of the glass to
be protected.
…Range will be reduced in areas that are acoustically soft. This
may be due to carpeting, drapes, plants, or other sound
absorbing materials. The DS1110i Glass Breakage Tester should
be used to verify range in all installations.
…Glass break detectors are intended only as a component of a
perimeter protection system. They should always be used in
conjunction with motion sensors.
…Glass breakage detectors are designed to detect the breakage
of framed glass and may not detect such things as bullet holes,
spontaneous breakage of glass (with no impact), and removal
of glass.
• Maximum range:
The maximum detection range is 25 ft. (7.6 m) from the farthest corner, for glass sizes 12" by 12" (0.3 m by 0.3 m) and larger.
Hint: Tie a 25 ft. (7.6 m) string to the detector. The string should be
able to touch every part of the glass being protected. If any
part of the glass can not be touched by the string, it is outside of the detector’s coverage and additional detectors
should be used.
3.0 Selecting a Mounting Location
Opposite Wall Mounting
• Mount the detector where there are no objects between itself and
the glass.
• Do not mount the detector
closer than 5 ft. (1.5 m) to the
wall that the glass being
protected is on, or any hard,
sound reflecting surface.
• The detector should be within
±30° of the center of the glass
to be protected (line B in Figure A).
• Make sure the detector is no farther than 25 ft. (7.6 m) from any
corner of the glass (line A in Figure A).
Ceiling Mounting
• The recommended location
is half the distance between
the glass and its opposite
wall or 2/3 of the rated range,
whichever is smaller.
• Mount the detector where
there are no objects between
itself and the glass.
• Mounting to drop ceiling tiles
is acceptable.
• Do not mount the detector closer than 5 ft. (1.5 m) to the wall that
the glass being protected is on, or any hard, sound reflecting
surface.
• Make sure the detector is no farther than 25 ft. (7.6 m) from any
corner of the glass (line A in Figure B).
• The detector should be within ±30° of the center of the glass to
be protected (line B in Figure B).
Adjacent Wall Mounting (not preferred)
• Mount the detector where there are no objects between itself
and the glass.
• Do not mount the detector
closer than 5 ft. (1.5 m) to the
wall that the glass being
protected is on, or any hard,
sound reflecting surface.
• Make sure the detector is no
farther than 25 ft. (7.6 m) from
the farthest corner of the glass
(line A in Figure C).
Multiple Detectors
In some installations, multiple detectors must be used to protect larger
glass.
As a general rule, if the glass is wider
B
than 20 ft. (6.1 m), multiple detectors
should be used.
A
A
• Place each detector in-line with
the center of each 20 ft. (6.1 m)
section of glass.
• Space the detectors evenly
Figure D
across the glass, but no farther
than 20 ft. (6.1 m) apart (line B in Figure D).
• Do not mount the detector closer than 5 ft. (1.5 m) to the wall that
the glass being protected is on, or any hard, sound reflecting surface.
• Make sure each detector is no farther than 25 ft. (7.6 m) from any
corner of its 20 ft. (6.1 m) section (lines A in Figure D).
4.0 Testing
Testing the Location
• T emporarily mount the detector using 2-sided tape.
• Power the detector using a 9 Volt battery .
• The detector will enter the test
mode, for five minutes, as soon
as power is applied. The detector
will indicate that it is in the test
mode by flashing the LED for 10

seconds. At the end of five
minutes the detector will flash the
LED again for 10 seconds to

ON
indicate the test period is over.
The test mode can be restarted
at any time by powering the unit
off and then on or by placing a

Switch
magnet next to the “T” on the
cover. Placing a magnet next to
the ”T" when the unit is in the test mode will terminate the test.
NOTE: All testing should be done with the detector’s cover in place.
TEST #1: ENVIRONMENTAL TEST
Remember: The detector must be in test mode to perform this
test.
During the 5 minute test mode, the LED will indicate low or high frequency
disturbances by flashing at specific rates. Occasional (random) flashes
of the LED are normal. To rule out random flashes affecting this test,
observe the LED for the full five minutes.
• Turn on all sources of noise (e.g. forced air blowers, air conditioners,
compressor motors, etc.).
• The LED will flash 5 times per second each time a low frequency
disturbance is detected. If the 5 flashes per second occur more
than once every 15 seconds or if the unit alarms, then do not mount
in this location.
• The LED will flash once each time a high frequency disturbance is
detected. If any flashes occur more than once every 15 seconds, do
not mount in this location.
Remember: If the detector happens to alarm during this test, the alarm
relay will activate as well.
NOTE: If disturbances exist while positioning the detector in-line with
the center of the window, then the detector may be moved within
a 60° (±30°) arc of the window’s center.
TEST #2: RESPONSE TEST
Remember: The detector must be in test mode to perform this
test.
This test should be performed using the DS11 10i Glass Breakage Tester.
The DS11 10i produces a high frequency tone designed to alarm the unit
to further verify proper location.
CAUTION: Don’t point the tester directly at your or anyone’s ear. Doing
so could damage hearing.
• Hold the DS1110i Glass Breakage
Tester against the window being
tested and point it at the detector.
- If there are curtains or blinds
covering the window, close them
over the T ester .
• Activate the T ester.
- Setting the T ester to automatic mode

causes it to activate every 6 seconds.
This will allow you to better observe the detector’s LED.
- For large windows, perform this test at different placements along
the window.
• The alarm/test LED and the alarm relay will activate for three
seconds if this is an acceptable detector placement.
NOTE: The low frequency response of the detector can be tested (while
still in the test mode) by opening a door about 1 inch and
slamming it shut. The detector should indicate an alarm.
• During the last 10 seconds of the detector’s test mode, its LED will
pulse. To end the test mode before the 5 minute time-out period,
place a magnet next to the “T” on the detector case.
