GLASS BREAK ADJUSTMENT
To adjust the glass break setting
(increase/decrease sensitivity) place the
jumper JP1 below the GLASS marking
(connecting the middle pin with the left pin) -
(See Fig. 4) Green LED is constantly ON.
Now you can adjust the sensitivity by rotating
the right potentiometer (marked as GLASS
CALIB. - see Fig. 4).
Operate the Sound Break Simulator and rotate
the potentiometer clock-wise to increase
sensitivity, and counter-clock-wise to decrease
sensitivity until the Yellow and Red LED's are
illuminating for each glass break sound.
Remember that rotating the potentiometer will
have no effect upon the settings if the middle
pin of JP1 is not connected to the left pin.
Note
• When the jumper is set for GLASS
adjustment, only the high frequency sound of
breaking glass is detected.

THE MEMORY FUNCTION
The alarm memory function allows the identification
of an alerting detector out of multiple detectors
connected to one (or the same) zone of the control
panel.
To enable this function, Set on jumper JP3
(
See Fig. 4)
connected on both pins -
•
the red LED will stay
In case of an alarm,
ON until
until memory function is reset.
To reset the memory function, switch off
the voltage wire (+12V) from the
(disconnect)
TERMINAL BLOCK (See Fig. 4) for minimum
15 seconds
then switch on (reconnect)
wire (+12V)
.
(The control panel key ON/OFF can be used
for this application if it control
(+12V)
.

SHOCK ADJUSTMENT
To adjust the shock setting (increase/decrease
sensitivity) place the jumper JP1 below the
SHOCK marking (connecting the middle pin
with the right pin) - (See Fig. 4) Yellow LED is
constantly ON.
Now you can adjust the sensitivity by rotating
the left potentiometer (marked as SHOCK
CALIB. - see Fig. 4).
Hit gently on the protected glass and rotate
the potentiometer clock-wise to increase
sensitivity, and counter-clock-wise to decrease
sensitivity until the Green and Red LED's are
illuminating for each hit.
Remember that rotating the potentiometer will
have no effect upon the settings if the middle
pin of JP1 is not connected to the right pin.
Note
• When the jumper is set for SHOCK
adjustment, only the low frequency of the
shock signal prior to glass breakage is
detected.

SENSITIVITY SETTING
For some installations you may find that GBD-

JP2 CONNECTED - 50% sensitivity
FINAL TESTING
•
Make sure to disconnect the jumper at
JP1. When the jumper is disconnected, the
detector will detect both shock and sound
frequencies.
•
To ensure maximum protection against
false alarms, activate any device in the
area, which might automatically cycle
pumps, generators, heating/air conditioning
units, etc. If the cycling devices trigger an
alarm, mount the unit in a different location.
WIRE SIZE REQUIREMENTS
Use #22 AWG (0.5mm) or wires with a larger
diameter. Use the following table to determine
required wire gauge (diameter) and length of
wire between the detector and the control
panel.
