Acoustic Glass Break Detector

Installation Manual

APPLICATION

The GS930 is an acoustic glass break detector designed to detect break-

ing glass from framed windows in the perimeter of building. The detector

can safely and reliably detect glass breakage on both small and large ob-

jects as well as on single or multiple glazed objects.

INSTALLING THE DETECTOR (FIGS. 1 TO 7)

Select a mounting position for the detector that is on a wall or ceiling adja-

cent to, or across from, the glass surface being monitored;

• Only use for indoor installations;

• Do not expose to any direct airflow;

• Must 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.

In VDS-approved systems, the detector cover must be sealed with

an additional screw (enclosed with the detector) (Fig. 8).

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.

• Do not use in 24 hour-monitoring zones.

PROGRAMMING (FIG. 6)

Power /status LED (Green) Jumper J3

Off Open

On Closed

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.

Alarm LED (Red) Jumper J4 RESET Input

Flashing for 2.5 sec Open Open

Latched after alarm Closed Open

Follows alarm relay Closed Permanently LOW

RESET Closed With LOW

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 (FIGS. 5 & 9)

High-frequency range testing:

• Remove the detector cover;

• 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;

• Replace the detector cover;

• 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;

• Slide the tester switch to TEST position, and a simulated glass break

sound will be produced every 10 seconds. If the glass is within range, the

flashing LED will latch for 2.5 sec. At the same time the alarm relay is

opened so that the appropriate detection line on the alarm control unit

will trip.

Low-frequency range testing:

• To enter this mode while in the high-frequency test mode, press the

test button (SW2) a second time. The LEDs will now flash alternately at

a slower rate.

• A sharp blow of the hand or other firm object to a framed hollow wall,

ceiling or door will cause the flashing LEDs to latch for 2.5 sec. and the

alarm relay to open.

IMPORTANT: This test is not a range check.

The test mode lasts 5 minutes after which the detector automatically resets

to the normal operation mode. To manually exit the test mode, press the test

button until the LEDs stop flashing.

FUNCTIONAL TEST IN NORMAL OPERATION

• The detector must be in the normal operation mode with the cover in

place.

• Hold the GT-2 tester directly against the glass surface to be protected

while aiming the loudspeaker towards the detector. Set the mode

selection switch to RUN.

• Slap the glass to be protected with your flat hand. The unit automati-

cally produces a loud simulated glass break sound.

• If the detector has been correctly installed, this should trigger an alarm.
