Description
GS930 is an acoustic glass break detector designed to detect
breaking glass from framed windows in the perimeter of
building. The detector can safely and reliably detect glass
breakage on both small and large objects as well as on single
or multiple glazed objects.
Installing the detector
See Figures 1 to 7.
Select a mounting position for the detector that is on a wall or
ceiling adjacent to, or across from, the glass surface being
monitored.
•
Only use for indoor installations.
•
Do not expose to any direct airflow.
•
Have a line-of-sight view of all glass surfaces to be
protected.
•
Locate it no further than 8.5 m and not less than 1.0 m
from the glass.
•
Mount it at least 0.15 m away from an adjacent wall or
ceiling and at least 1.8 m from the floor.
•
Can be temporarily mounted to conduct an initial
functional test.
•
Must be permanently mounted on a stable and vibration-
proof surface.
•
When closing the cover, ensure that the tamper contact
spring is fed into the recess in the cover.
Special notes
•
Do not mount the detector on the same wall as the glass
surface being protected.
•
If the glass is covered by inside shutters or sound-
deadening drapes, or where exhibits or display items
conceal the detector, check that the detector is operating
correctly before permanently mounting it (see Functional
testing during installation).
•
Do not use only one detector to protect glass in multiple
rooms even if the range test indicates the detector is
operating correctly. This is a precaution in case doors or
other partitions are later placed between the rooms.

Programming
See Figure 6.
Power /status LED (Green)
Off
On
When closing the pins of jumper J3, the green LED remains lit
when power is applied to the detector. The green LED will
extinguish for one second when a loud sound occurs in the
upper frequency rage, noting a pre-trip condition. However, an
alarm is not activated unless the other sound characteristics
required by 3 x 3 technology are also present.

Latched after alarm Closed
Follows alarm relay Closed
RESET Closed
When an alarm occurs, the red alarm LED flashes for 2.5 sec.
When latched, the LED will indicate a new alarm by flashing for
2.5 sec. and re-latching afterwards. The latched LED can be
reset by applying a LOW signal to the RESET input.
Functional testing during installation
See Figures 5 and 9.
High-frequency range testing
1. Remove the detector cover.
2. Apply power and press the test button (SW2) once. The
red and green LEDs will start to quickly flash alternately.
The detector is now ready for high-frequency range
testing.
3. Replace the detector cover.
4. Set the GS905 tester mode to Single. Select the
appropriate glass type (Plate, Tempered, or Laminated).
5. Hold the tester near the surface of the glass to be
protected and aim the speaker at the detector from the
furthest point of the glass. If there are closed curtains, hold
the tester behind them.
