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
than 20 ft. (6.1 m), multiple detectors
should be used.
• Place each detector in-line with
the center of each 20 ft. (6.1 m)
section of glass.
• Space the detectors evenly
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
• Temporarily 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
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
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 DS1110i Glass Breakage Tester.
The DS1110i 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 Tester.
• Activate the Tester.
- Setting the Tester 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.
