Description
The DG-50 is an acoustic glassbreak detector
designed to listen for the specific sonic frequencies
of breaking glass. The DG-50 is equipped with multi-
level discriminating circuitry to maximize its response
to breaking glass and minimize its response to
normal environmental noises. As well, the DG-50 is
extremely resistant to seismic shock and will not
alarm in response to a slamming door or even a tap
on the case.

As with all DSC products, the DG-50 Glassbreak Detector has been designed with careful attention to the smallest details.
The DG-50 incorporates features and renements which make it superior to any other product of its kind and provides
accuracy and reliability which are second to none.

Locating the Detector
Since the energy of breaking glass is transmitted
through the air, the location of the detector, relative
to the window(s) to be protected and the furnishings
in the room are important considerations.
Sound absorbing materials such as curtains, rugs,
acoustic tile, wall coverings and plush furniture
reduce the energy received by the detector. To
assist in establishing proper operation, use the DG-
50ST acoustic tester and adjust the sensitivity as
required.
Sensitivity Adjustment
If the sensitivity is too high, turn the adjustment
counter-clockwise and if reliable detection is not
achieved, increase the sensitivity by turning the
adjustment clockwise. Sensitivity should not be
adjusted any higher than necessary to achieve
reliable detection.
Setup
Use the double-sided tape provided with the
detector to temporarily mount the detector in the
selected location and with the DG-50ST tester,
verify that the detector responds consistently.
Place the DG-50ST tester against the window to be
protected and operate 3 times. If the detector does
not respond each time, relocate the detector or
adjust the sensitivity and repeat the test. If there are
multiple windows or one large window, use the
tester at the extreme location. When the detector
responds consistently, it can be permanently
mounted using the supplied screws.
If there are drapes or curtains that can be closed to
cover the window(s), they should be closed for the
setup tests. Hold the DG-50ST tester between the
drapes and the window. If the curtains or drapes
prevent reliable detection, it is suggested that the
detector be mounted behind the drapes either on
the wall or the ceiling.
Mounting the DG-50
Once the location has been determined, open the
detector by pressing the release tab on the bottom
with a small flat-blade screwdriver. Remove the
cover and set in a safe location. Draw the wires
through the rectangular opening in the backplate
and connect to the terminal block. Observe polarity
for power wiring. Mount the detector using the two
mounting screws. Once the detector is permanently
mounted, repeat the installation tests using the DG-
50ST tester to confirm proper operation.

Limited Warranty Digital Security Controls Ltd. warrants
that for a period of twenty-four months from the date of
purchase by the original buyer, the product shall be free of
defects in materials and workmanship under normal use and
that in fulfilment of any breach of such warranty, Digital
Security Controls Ltd. shall, at its option, repair or replace
the defective equipment upon return of the equipment to its
factory. This warranty applies only to defects in parts and
workmanship and not to damage incurred in shipping or
handling, or damage due to causes beyond the control of
Digital Security Controls Ltd. such as lightning, excessive
voltage, mechanical shock, water damage, or damage
arising out of abuse, alteration or improper application of the
equipment.
The foregoing warranty shall apply only to the original buyer,
and is and shall be in lieu of any and all other warranties,
whether expressed or implied and of all other obligations or
liabilities on the part of Digital Security Controls Ltd. This
warranty contains the entire warranty. Digital Security
Controls Ltd. neither assumes, nor authorizes any other
person purporting to act on its behalf to modify or to change
this warranty or liability concerning this product.
In no event shall Digital Security Controls Ltd. be liable for
any direct, indirect or consequential damages, loss of
anticipated profits, loss of time or any other losses incurred
by the buyer in connection with the purchase, installation or
operation or failure of this product.
Warning: Digital Security Controls Ltd. recommends that the
entire system be tested on a regular basis. However, despite
frequent testing, and due to, but not limited to, criminal
tampering or electrical disruption, it is possible for this
product to fail to perform as expected.
DG-50 USED WITH TEMPERED GLASS
To ensure glass break detection on tempered plate
glass, the DG-50 must be mounted directly in front of
the surface to be protected at a maximum distance
of 12 feet and a minimum distance of 5 feet. For
difficult applications location of the unit must provide
a direct line-of-sight between the DG-50 and the
protected glass at an angle not to exceed 45 degrees.
A rule of thumb for most applications is to locate the
DG-50 approximately the same distance from the
surface to be protected as the distance between the
center of the glass and the ceiling of the room.
