1.1 Coverage
10 ft (3 m) maximum to farthest point of glass being protect-
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
Directly (or using the supplied bracket) to a ceiling, wall, door
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
Normally Closed (NC/C) reed relay contacts rated 3.5 Watts,
125 mA @ 28 VDC for DC resistive loads. Protected by a 10
ohm resistor in the common “C” leg. The contact opens for 3
sec upon a glassbreak alarm. For a magnetic contact alarm, the
contacts remain open as long as the magnet is more than 1 - 2
inches away from the detector.
1.6 Tamper
Normally Closed (NC/C) rated 125 mA @ 28 VDC maximum.
For UL Listed Requirements, the tamper switch must be con-
nected to a 24 hr protection circuit.
1.7 Operating Temperature
-20° to +120°F (-29° to +49°C). For UL Listed Requirements,
the temperature range is +32° to +120°F (0° to +49°C).
1.8 Enclosure
ABS high impact plastic. 1.25 in H x 3.75 in W x 0.875 in D (32
mm H x 95 mm W x 23 mm D).
1.9 Accessories
DS1110i Glass Breakage Tester. mm) Plate glass (DSB).
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.

Single Window Coverage Using the Magnetic Contact
Mount the detector where there are no objects be-
•
tween itself and the glass.
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
fi
gure 3.5).
The detector should be within ±30° of the center of
•
the glass to be protected (line B in
fi
gure 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.
