3. Description
Glass-break detection
The detector will report an alarm when it detects a low frequency sound (impact) followed by
a high frequency sound (glass break) in less than 4 seconds. The alarm is signaled by the
alarm output for 2 seconds.
Supply voltage supervision
The detector will report a trouble when the supply voltage drops below 9 V (±5%) for more
than 2 seconds. The trouble results in turning on the alarm output. The alarm output remains
on as long as the trouble exists.

low supply voltage – ON.
TEST pins to enable/disable the test mode (jumper installed – test mode disabled;
jumper removed – test mode enabled). In the test mode, the detector reports an alarm
when it detects a high frequency sound (glass break sound).

4. Selecting a mounting location
The detector is designed for indoor installation.
The detector microphone should be directed towards the protected glass, so the best
place to mount the detector is the wall opposite the protected glass.
The distance between the detector and the protected glass must not exceed the detection
range (6 m).
There must be no objects between the detector and the glass.
The detection range depends on the room acoustics. The shades, curtains, furniture
upholstery, acoustic tiles, etc. absorb the sound and adversely affect the detector
operating range.
Do not mount the detector on the same wall as the protected glass.

5. Range test
Check that the detector located in the selected installation location can detect the glass-
break. A temporary 12 V DC power supply will be needed for the test.
1. Open the detector enclosure.
2. Remove the electronic board.
3. Make an opening for the wires in the enclosure base.
4. Run wires through the prepared opening to a temporary 12 V DC power source.
5. Secure the electronics board.
6. Connect the power wires to the +12V and COM terminals.
7. Remove the jumper from the TEST pins.
8. Close the detector enclosure.
9. Put the detector at the planned installation place.
10.Power up the detector.
11.Place the INDIGO TESTER close to the protected glass and use it to generate a glass-
break sound.
12.If the detector reports an alarm, proceed to the next steps. If the detector fails to report an
alarm, increase sensitivity or select another installation location and repeat the test.
13.Power down the detector.
14.Open the detector enclosure.
15.Disconnect the power wires.
16.Place the jumper on the TEST pins.
6. Installation
Disconnect power before making any electrical connections.
1. Remove the electronic board.
2. Make the openings for screws in the enclosure base.
3. Run wires through the opening prepared earlier.
4. Use screws to secure the enclosure base to the mounting surface.
