Product Information

DS1101i/1102i/1108i Glass Breakage Detectors

• The DS1101i/1102i/1108i Glass Breakage Detectors are devices designed to detect and alert users to the sound of breaking glass. They are suitable for use with various types of glass, including Plate, Tempered, Laminated, and Wired glass.
• These detectors should be installed on the same wall as the glass being protected, with obstructions between the glass and the detector. They should be mounted closer than 5 ft. (1.5 m) to the wall that the glass is on, or any hard, sound-reflecting surface. It is important to avoid mounting them closer than 2 ft. (0.6 m) to heating or cooling outlets to prevent drafts from affecting the detector’s performance.
• The detectors should be installed on 24-hour protection circuits and placed in areas that are not acoustically live, such as kitchens and bathrooms. It is recommended to use a delay zone to provide users with time to acknowledge false alarms. System users should be instructed on how to respond to false alarms.
• When selecting a mounting location, it is important to ensure that the detector’s coverage can touch every part of the glass being protected. If any part of the glass cannot be reached by the detector’s coverage, additional detectors should be used.
• In installations where larger glass areas need to be protected, multiple detectors can be used. As a general rule, if the glass is wider than 20 ft. (6.1 m), multiple detectors should be installed across the glass, with each detector placed in the center of each 20 ft. (6.1 m) section of glass.
• The DS1101i/1102i/1108i Glass Breakage Detectors can be tested using the environmental test and response test. The environmental test checks for any interference from external sources such as loud noises or vibrations. The response test uses the DS1110i Glass Breakage Tester to simulate the sound of breaking glass and verify the detector’s proper location.

Product Usage Instructions

Installation Considerations:

• Always pre-test the detector’s location using the DS1110i.
• 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 to avoid drafts.
• Use the environmental test (see Section 4) to verify good installation locations.
• Install 24-hour protection circuits that are armed when occupied.
• Avoid acoustically live areas such as kitchens and bathrooms.
• Use a delay zone to provide the user time to acknowledge false alarms.
• Instruct system users on how to respond to a false alarm.

Selecting a Mounting Location:

The mounting location should allow the detector’s coverage to touch every part of the glass being protected. If any part of the glass cannot be touched by the detector’s coverage, additional detectors should be used.

Multiple Detectors:

If the glass being protected is wider than 20 ft. (6.1 m), multiple detectors should be installed across the glass. Each detector should be placed in the center of each 20 ft. (6.1 m) section of glass.

Testing:

Perform this test with the detector in test mode.

1. Ensure the detector’s cover is in place.
2. Expose the detector to various environmental conditions, such as loud noises or vibrations, for five minutes.
3. The detector will indicate the test mode by flashing the LED for 10 seconds at the start and end of the test period.

Response Test:

Perform this test with the detector in test mode and using the DS1110i Glass Breakage Tester.

1. Ensure the detector’s cover is in place.
2. Point the DS1110i Glass Breakage Tester against the window being protected.
3. The DS1110i will produce a high-frequency tone designed to trigger the detector and verify its proper location.
4. CAUTION: Do not point the tester directly at your or anyone’s ear to avoid potential hearing damage.

Installation Considerations

• NOTE: Always pre-test the detector’s location using the DS1110i 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, DS1102i, or DS1108i 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 on 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 oppo-site wall of the glass being protected. Do not exceed the maximum range.
• The detector should be within ±30° of the center of the glass to be protected.
• The 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 the 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.

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 Fig- ure 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 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).

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 Alarm/Test LED power is applied.
• The detector will indicate that it is in the test – + NO C NC T Tmode by flashing the LED for 10 seconds.
• At the end of five minutes, the detector will flash the LED again for 10 seconds to OFF ON indicating 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.

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.

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 the 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.

Mounting and Setup

Mount the Detector

• After verifying an acceptable location, permanently mount the detector.
• The detector can be mounted using the one center screw or with two screws for more stability.
• If mounting using the center screw only, the circuit board does not need to be removed.

If mounting using two screws:

• Remove the circuit board from the enclosure by pushing back the two retainer tabs and lifting out the circuit board.
• Use the two mounting holes in the enclosure to secure it to the mounting surface.
• Replace the circuit board.

Install Wiring

• CAUTION: ONLY APPLY POWER AFTER ALL CONNECTIONS HAVE BEEN MADE AND INSPECTED.
• NOTE: Do not coil excess wire inside the unit.
• NOTE: For Canadian installations, install in accordance with the Canadian Electrical Code.

Select LED Latching Mode

• ON: The LED will latch on when the unit is alarmed and will stay on until it is reset. Momentarily interrupt input power to reset the LED.
• OFF: The LED will not latch after an alarm.
• NOTE: If the jumper is removed or missing, the LED Latching Mode will default to OFF.

Setup and Testing

• Replace the detector’s cover, install a tamper screw (if desired), then apply power.
• Re-test the unit with the DS1110i Glass Breakage Tester.

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 operating mode and does not require that the detector be in the test mode.
• The DS1101i/1102i/1108i are protected by the following patents: 5,450,061 and #5,438,317.
