ed. For glass sizes over 12 in x 12 in (30 cm x 30 cm); types of
1/4 in (64 mm) Plate, Tempered, Laminated, and Wired glass;
and 1/8 in (32 mm) Plate glass (DSB).
1.2 Mounting

or window frame.
1.3 Input Power
12 VDC (6 VDC min to 15 VDC max), 23 mA nominal @ 12 VDC
(29 mA max in the LED Latch mode).
1.4 Standby Power
Connect to power sources capable of supplying standby power
of 23 mAh for each hr of required standby time. Four hr mini-
mum standby time required for UL Listed Requirements.
1.5 Alarm Relay

For UL Listed Requirements, the tamper switch must be con-
nected to a 24 hr protection circuit.

2 Installation Considerations
NOTICE!
Always pretest the detector’s location using the
DS1110i Glass Breakage Tester.
Do Not:
Mount the detector on iron or steel surfaces if the mag-•
netic contact will be used. Aluminum and stainless stell
frames are acceptable.
Mount the detector with obstructions between the glass•
being protected and the detector.
Mount closer than 2 ft (61 cm) to heating or cooling out-•
lets; 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 6) to
verify good installation locations.
Install alarm contacts on 24 hr protection circuits.•

Mounting Above Glass Doors
Mount the DS1109i at the top of the door frame with•
the Sensor Aperture pointing downward.
Mount the magnet to the top of the door. The magnet•
should be placed so that it aligns with the side of the
DS1109i. Do not allow the magnet to cover the front of
the detector. See Figure 3.2.
The detector must be mounted so that the door swings•
outward from the detector. See Figure 3.3.

Mount the detector where there are no objects be-•

Make sure the detector is no farther than 10 ft (3 m)•
from the farthest corner of the glass (line A in Figure
3.4).
Do not mount the unit with the Sensor Aperture facing•
away from the window.

Ceiling Mounting Without the Magnetic Contact
The recommended location is half the distance be-•
tween the glass and the opposite wall or 7 ft (2.1 m)
whichever is smaller.
Mount the detector where there are no objects be-•
tween the glass and itself.
Make sure the detector is no further than 10 ft (3 m)•
from any corner of the glass (line A in figure 3.5).
The detector should be within ±30° of the center of•
the glass to be protected (line B in figure 3.5).
Jumper P3 must be installed to disable the magnetic•
contact. See Section 5.
Figure 1.1: Board Layout
If you must install the DS1109i in a zone that is armed•
when occupied:
Avoid acoustically live areas such as kitchens and bath-•
rooms.
Use a delay zone to allow time to acknowledge user caused•
false alarms.
Instruct users of the system how to respond to such an•
alarm.
Remember:
The best mounting location is less than 10 ft (3 m) from•
the glass, and in direct line of sight of the glass. Do not
exceed the maximum range.
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 break-•
age of framed glass and may not detect such things as bul-
let holes, spontaneous breakage of glass (with no impact),
and removal of glass.
Maximum Range:
The maximum detection range is 10 ft (3 m) from the farthest
corner, for glass sizes 12 in x 12 in
(30 cm x 30 cm) and larger.

Mounting the Detector
After verifying an acceptable location, permanently•
mount the detector. Use the two mounting holes in the
enclosure to secure it to the mounting surface.
Mount the detector and the Contact Magnet within 1•
in (2.5 cm) of each other. The Contact Magnet must be
mounted facing the side of the detector with the Sen-
sor Aperture. See Figure 3.6.

6 Installing the Tamper Screw
Install the tamper screw as shown in Figure 6.1.
Do not mount the magnet so it covers the Sensor•
Aperture.
Avoid misaligning the detector and the magnet.•
5 Setting the Jumpers
The DS1109i has two jumpers located on the main board. P2
is used to allow the LED to latch on to a glass breakage alarm.
P3 is used to determine if the magnetic contact is used.
Remove the jumper from P2 if you do not want the LED•
to latch into alarm when a glass breakage occurs. The
relay contacts will only change state for approximately 3
sec upon a glass breakage alarm. The LED may be reset
by a momentary interruption of the power.
Remove the jumper from P3 if you want to use the mag-•
netic contact.

7 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 min as•
soon as power is applied. The detector will indicate that
it is in the test mode by flashing the LED for 10 sec. At
the end of five min the detector will flash the LED again
for 10 sec 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 pressing the Test Switch (see the
Board Layout drawing). Pressing the Test Switch when
the unit is in the test mode will terminate the test.
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, observethe LED for the full
5 min.
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 sec 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 sec, do not mount in this location.
Remember: If the detector happens to alarm during this
test, the alarm relay will activate as well.
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 Break-
age Tester. The DS1110i produces a high frequency tone
designed to alarm the unit to further verify proper location.
NOTICE!
Adjacent wall mounting is not recommended
for this detector.
CAUTION!
Don’t point the tester directly at your or any-
one’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. See Figure 7.1.
DS1110i Tester
Hold against window and
point at detector.
NOTICE!
The low frequency response of the detector can
be tested (while still in the test mode) by open-
ing a door about 1 inch and slamming it shut.
The detector should indicate an alarm.
Activate the tester. Setting the Tester to automatic•
mode causes it to activate every 6 sec. This will allow
you to better observe the detector’s LED.
For large windows, perform this test at different place-•
ments along the window.
The alarm/test LED and the alarm relay will activate for•
three sec if this is an acceptable detector placement.
NOTICE!
All testing should be done with the detector’s
cover in place.

4 Wiring the Detector
Wire the detector as shown in Figure 4.1. Leave extra•
wire so the case can be opened for testing.
Magnet
DS1109i
During the last 10 sec of the detector’s test mode, its•
LED will pulse. To end the test mode before the 5 min-
ute time-out period, press the Test Switch.
Automatic Sound Check
This detector features Automatic Sound Check, to allow the
end user to test the unit on a periodic basis. To perform the
test, simply clap your hands or create some other loud sound.
When the detector hears this sound the LED (but not the alarm
relay) will activate. This feature works in the normal operat-
ing mode and does not require that the detector be in the test
mode.
It is recommended that a full Response Test (as outlined
above) and magnetic contact test (if used) be performed on an
annual basis.
