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.
