GBD-II
SHOCK & BREAKAGE
GLASS BREAK DETECTOR
ELECTRONIC ENGINEERING LTD.
INSTALLATION INSTRUCTIONS
P/N 7101108 Ver. 2.0 A.Y.
The GBD-II is the ultimate answer for all those
tired of false alarms. It listens for sounds of
breaking glass, which produce two sequential
signals of different frequencies. The unique
phased frequency detection circuitry of this
detector allows detection of both shock signal
and the strong signal of glass breakage
creating a “false alarm free” glass break
detector.
The detector does not need to be attached to
the window, providing volume protection, and
allowing you to protect several windows with
one detector.
FEATURES
•Phased Frequency Detection system,
detects low frequency impact sound as well
as the glass breakage sound thereby
eliminating false alarms.
•Separate sound & shock adjustment.
•Memory function.
•Volume protection.
•Ceiling or wall mounting.
FIG. 1 - MOUNTING
The detector offers flexible installation. It can
be Either ceiling mounted or wall mounted as
shown in the figure above.

MOUNTING LOCATION ( See FIG. 1 )
•If heavy blinds or curtains cover the glass,
you must locate the detector behind the
blinds on the window frame or above it,
otherwise the blinds might block the sound.
Make sure to test the unit thoroughly for
proper detection.
•Install the detector in a direct line of sight
with the protected glass.
•Do not mount the unit in front of air ducts,
or close to bells (measuring 0.5m (or
larger) in diameter).
•For a few protected glasses in one room,
locate the detector in optimal distance from
them to achieve the best detection.
Note: for symmetrical cover of the detection
area it is recommended to place the
detector on the ceiling.
MOUNTING THE DETECTOR ( FIG. 2 )
1. Use a small screwdriver to push the prong
on top of the case and open the case.
2. There is no need to remove the PCB
(Printed Circuit Board) from the case.
3. Insert the wires through the wiring hole (B).
4. Use the mounting holes (A) to mount the
detector.
5. Connect the wires to the terminal.(See
Terminal Connections)
6. Close the case.
JUMPERS ( FIG. 4 )
•JP1 - Shock / Glass selector for detection
calibration.
•JP2 - Reduces the sensitivity of sound
detection by 50%.
•JP3 - Latch. See The Memory Function.

FIG. 3 - TERMINAL BLOCK
TERMINAL BLOCK CONNECTIONS
Terminal 1 - Marked -( -12V )
Connect to the negative Voltage output or
ground of the control panel.
Terminal 2 - Marked + ( +12V )
Connect to the positive Voltage output of 9-16
Vdc source (usually from the alarm control unit)
Terminals 3 & 4 - Marked TAMPER
If a Tamper function is required connect these
terminals to a 24hour normally closed protective
zone in the control unit. If the front cover of the
detector is opened, an immediate alarm signal will
be sent to the control unit.
Terminals 5 & 6 - Marked RELAY
These are the output relay contacts of the detector.
THE CALIBRATION TOOL ( * )
The Simulator/Tester & Calibration tool is
especially designed to check phased
frequency glass break detectors.
Since the detector will react to the high
frequency breakage sound only when it comes
sequentially after a low frequency SHOCK
sound, this device is necessary to check for
proper operation of the GBD-II without actually
breaking the glass.
Manual mode:
In this mode, the Simulator will emit the high
frequency sound of breaking glass for "Glass"
adjustment.
Automatic mode:
In order to simulate breaking glass, place the
Simulator on the surface of the protected
glass, and gently hit it with your hand. The
Simulator will then emit the sound of breaking
glass. Be careful not to break the glass while
testing the detector.
∗It is recommended to use simulator CROW
P/N: 0040011
TESTING THE DETECTOR
First use the Simulator in manual mode to
simulate the noise of glass breaking. Check
that the yellow LED is ON. If it does not light,
the sensitivity calibration is necessary (See
Sound Calibration).
Now use your hand or a padded object to
carefully strike the glass. If the green LED
does not light, adjust as necessary (See
Shock Calibration).
Now use the Simulator in automatic mode and
check that the red LED lights. If the red LED is
ON, your detector is working properly.
Otherwise try adjusting the sound and shock
setting until the red LED lights.

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.
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-
II is too sensitive. Use JUMPER JP2 to
decrease sensitivity to 50%.
JP2 OPEN - 100% sensitivity
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.

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
(connected on both pins - See Fig. 4)
•In case of an alarm, the red LED will stay
ON until until memory function is reset.
To reset the memory function, switch off
(disconnect) the voltage wire (+12V) from the
TERMINAL BLOCK (See Fig. 4) for minimum
15 seconds then switch on (reconnect) voltage
wire (+12V).
(The control panel key ON/OFF can be used
for this application if it control the voltage
(+12V).
