Ver. G A.Y.

The GBD-PLUS is the ultimate answer for all
those tired of false alarms. It listens f or
sounds of breaking glass, whic h produc e two
sequential signals of dif f erent frequencies.
The unique phased frequency detection
circuitry of this det ector allows detection of
both shock signal and the strong signal of
glass breakage creating a “fals e al arm 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

• Shock and/or break age selectable

• Analyzes two frequencies

• Unique signal analysi s ignores

environmental disturbances

• Memory LED

• Sensitivity adjustment

• New ultra compact design

• Flush mount i nstallation (option)

• Outstanding detect i on range and reliabilit y

FIG. 1 - MOUNTING

The detector offers flexible ins tallation. It can
be either ceiling mounted or wall m ounted as
shown in the figure above.

MOUNTING LOCATION ( See FIG. 1 )

• I f heavy blinds or curtains cover the glass,
you must locate the det ector behind the
blinds on the window frame or above it,
otherwise the blinds might block the
sound. Make sure to test the uni t
thoroughly for proper detection.

• I nstall the detector in a direct l i ne of sight
with the protected glass.

• Do not mount the unit in front of air duc t s,
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 achi eve t he 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.

Snap out the detector PCB.

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 termi nal . (See
Terminal Connections)

6. Reinstall the detector P CB .

7. Close the case.

JUMPERS ( FIG. 4 )

• JP1 - Shock / Glass selec tor for detection
calibration.

• JP2 – Memory LED control.

• JP3 - Reduces the sensitivity of sound

detection by 50%.

FIG. 3 - TERMINAL BLOCK

TERMINAL BLOCK CONNECTIONS
Terminal 1 - Marked - ( GND )

Connect to ground of the control panel.

Terminal 2 - Marked + ( +12V )

Connect to the positive Volt age 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.
Connect to the control at zone input.

THE CALIBRATION TOOL ( * )

The Simulator/Tester & Calibration tool is
especially designed to check phased
frequency glass break detect o rs.
Since the detector will react to the high
frequency breakage sound only when it
comes sequentially after a low frequency
SHOCK sound, this device i s necessary to
check for proper operation of the GB D-P LUS
without actually breaking the glass .

Manual mode:
In this mode, the Simulat or will emit the high
frequency sound of breaking glass f o r " Gl ass"
adjustment.

Automatic mode:
In order to simulate breaki ng gl ass, place the
Simulator on the surface of the protected
glass, and gently hit it with your hand. T he
Simulator will then emit the sound of breaking
glass. Be careful not t o break the glass while
testing the detector.

∗ It is recommended to use simulator CROW

P/N: 0040011

TESTING THE DETECTOR

First use the Sim ul at or i n manual mode to
simulate the noise of gl ass breaking. Check
that the yellow LED is ON. If it does not light,
the sensitivity cali b rat i on i s 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 light s. If the red
LED is ON, your detector is worki ng properl y.
Otherwise try adjusting the sound and shock
setting until the red LED lights.

GLASS BREAK ADJUSTMENT

To adjust the glass break s etting
(increase/decrease sensi tivity) place the
jumper JP1 according the GLASS marking
(connecting the middle pin with the upper pin)

- (See Fig. 4) Green LED is const ant l y ON.
Now you can adjust the sensitivit y by rotating
the upper potentiometer (marked as GLASS
CAL. - see Fig. 4).
Operate the Sound Break Simulator and
rotate the potentiometer clock-wise to
increase sensitivit y, and counter-clock-wise to
decrease sensitivity unt i l 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 m i ddl e pi n of JP1 is not
connected to the upper pin.

Note

• When the jumper is set for GLASS
adjustment, only the hi gh frequency sound
of breaking glass is detec ted.

SHOCK ADJUSTMENT

To adjust the shock setting
(increase/decrease sensi tivity) place the
jumper JP1 according the SHOCK marking
(connecting the middle pin with the lower pin)

- (See Fig. 4) Yellow LED is const antly ON.
Now you can adjust the sensitivit y by rotating
the lower potentiometer (mark ed as SHOCK
CAL. - see Fig. 4).
Hit gently on the protected glass and rotate
the potentiometer clock-wise to increase
sensitivity, and count er-clock-wise to
decrease sensitivity unt i l t he 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 lower pin.

Note

• When the jumper i s set for SHOCK
adjustment, only the l ow frequenc y of the
shock signal prior to glas s breakage is
detected.

THE MEMORY FUNCTION

The alarm memory function allows the
identification of an alerti ng detector out of
multiple detectors connected to one (or the
same) zone of the control panel.
To enable this function, S et ON jumper JP2
(MEM) (connected on both pins - See Fig. 4)

In case of an alarm, the Red LED will stay
ON until memory function is reset.

To reset the memory function, switch OFF
(disconnect) the voltage wire (+12V) from the
TERMINAL BLOCK for minimum 15 seconds
then switch on (reconnect) voltage wire
(+12V).
(The control panel key ON/OFF can be used
for this application if i t control the voltage
(+12V).

SENSITIVITY SETTING

For some installat i ons you may find that GBD­plus is too sensiti ve. Use JUMPER JP3 to
decrease sensitivity t o 50%.
JP3 OPEN - 100% sensit i vity
JP3 CONNECTED - 50% sensi t i vi ty

FINAL TESTING

• Make sure to disconnect the j umper at
JP1. When the j umper is disconnected,
the detector will detect both shock and
sound frequencies.

• To ensure maximum protec tion against
false alarms, ac tivate any device in the
area, which might automati cally cycle
pumps, generators, heati ng/ ai r
conditioning units, etc . If the cycling
devices trigger an alarm, mount the unit in
a different location.
