4.0 Mounting Considerations
4.0.1 Circumstances to Avoid
Avoidelectrical and mechanical devicesthatmay create mechanical vibra-
tions in the protected structure. This includes, but is not limited to: Electric
Motors,Transformers,Fans,AirConditioners,Water Pipes,Ultrasound
Detectors,Bells.HumanActivitymay also be a factor.
4.1 Range
The range of the detector is dependent on the sensitivity setting of the de-
tector and on the type of material used in the construction of the vault, safe
or ATM. Because the unit is dependent on the vibrations caused by an at-
tack,anygapsorcracksinthematerialwillresultinreducedperformanceof
thedetector.
First, it is necessary to determine the maximum range of
the detector, based on the type of material used to con-
structthevault,safeorATM, then the number of detectors
required for the installation can be determined.
4.1.1 Range Guidelines for Vaults
The following chart shows the range of the detector as a function of the
type of material used in construction of the protected area, the sensitivity
setting on the detector and the possible methods of attack. These figures
should only be regarded as a guide in planning an installation. The actual
range is determined on site with a field test. Range can vary significantly
depending on construction material.

4.1.2 Layout Plans for a Vault Protection
As a general rule, a detector should be placed on each wall, floor, and
ceiling inside the vault. A detector should also be placed inside or on the
vaultdoor.Thedetectorsshouldbe surfaceorrecessmounted,andplaced
highenoughto keepclear ofsafes,documentcabinets,anddepositboxes.
It is recommended that a written plan be prepared to define the location of
each detector on the vault. This will enable you to determine the amount of
detectors needed to give the vault complete coverage. A fold out plan will
help in doing this (see the following diagram).

5.0 Planning the Installation - General Consider-
ations
The detection ranges shown in this guide are intended as guidelines for
ideal installation conditions. Actual detection range may be affected by
situationssuchaspartitionsinside the safe and non-continuous surfaces in
thesafe’sconstruction. Typically, one detector is used to protect each safe
door. It is important to test the installation thoroughly.
5.1 Planning Safe and Cabinet Protection
5.1.1 Safe and Document Cabinets - Multiple Detectors
Ifmounting inside the body,mounta detector onaspace which is clearand
easily accessible (e.g. the ceiling). Also mount a detector on the inside of a
door, close to the hinges. It is advisable to also add a magnetic contact to
the door.
If mounting outside the body, mount a detector on a wall at the same height
asthethedetectortobemountedonthedoor.Thedetectoronthedoormay
be mounted in one of three ways:
1. Mountedfixed, close to the hinge providing ashortdistanceto the junc-
tionbox.
2. Mounted on the key-hole protection plate to cover the key-hole. In the
armedposition, theleverwill cover thekey-hole. Connect thelevercon-
tact in series with the alarm output relay. This inhibits the arming of the
alarm system if the lever is still in the day position.
3. Mounted with the movable mounting kit. Mount so that the cable pre-
vents opening the door when the detector is in the night position plate.
Place the day position plate on a wall next to the opening side of the
door, or on a wall close to the safe.
The following drawing shows examples of these 3 mounting options.
Mounting Option 1 Mounting Option 2
Mounting Option 3
5.1.2 Safe/Document Cabinet Protection: one detector
If planning to protect a safe or document cabinet with only one detector,
mount the detector between and as close as possible to one of the door
hinges (either on the body or door) as shown in the diagram below. It is
advisable to add a magnetic contact to the door as well (this is required for
a UL Complete Mercantile safe rating).
5.1.3 Filing Cabinets
Normally the lock to the cabinet is located on one side
of an upper drawer. If so, mount the detector on the
side of the cabinet close to the lock.
If high security is required on one drawer in particular,
mountthe detector on that drawer. Mount the night po-
sitionplateonthedrawer and the day position plate on
the side of the cabinet.

DS1520/30Installation Instructions Copyright© 1995-97 DetectionSystems, Inc. Page 3
5.2 Planning Protection of
an ATM Unit
Typically, the door is the only exposed side
of the safe used in an ATM unit. When this
isthe case, an attackismost likely to occur
against the door, therefore the detector
shouldbemountedonthedoorformaximum
protection. Otherwise, the protection is
planned the same as for a safe.
5.3 Planning Protection of a
Night Deposit Box
The protection is planned the same as for
a safe. Soften/quiet the chute and landing
surface with rubber insulating material to
attenuate the noise created by the falling
cashboxes.
6.0 Installation
6.0.1 The Detector - Location of Major Items
The DS1520/DS1530 consists of a cast aluminum housing, with outside
dimensionsof 3x 33/4 x1inch(w,h, d)(8 cmx10cmx 3cm), anda weight
of 10.2 ounces.

6.1.2 Using the VS A6 Moveable Mounting Kit
The VS A6 is designed to enable Day and Night mounting locations for
the DS1520/DS1530 on vault, safe, and cabinet doors. In the Day
position, the tamper switch is open, preventing the system from being
armed. In the Night position, the detector is fully functional.
The kit includes the following:
-A magnetized mounting plate, to adhere to two smaller plates.
-Thetwosmaller plates.These twoplatesarecalledtheDay(unarmed
position) and Night (armed) plates. The magnet ensures an efficient
signal transmission between the Night plate and the detector.
•The cable for the installation should be wired through the VS A10 Junc-
tion Box.
•Mount the Junction Box and Day plate together on the side of the safe/
vault or a nearby wall so that cable will prevent the safe/vault door from
opening when the detector is moved to the Night plate.
•Mount the Night plate near the keyhole or dial of the door.
-Be careful when drilling into safe/vault doors. Some doors may have
printed circuit boards pre-installed behind the outer steel plate for drill
protection.
-Mounting the Night plate: remove paint or other surface finish on the
mountingsurface to guaranteeproperconnection.
•TheMoveable Mounting Platecontainsa reed switchanda microswitch.
Both determine whether or not the detector is properly in place.
-Wire these switches in series with the alarm relay of the detector.
-Only when the detector is on the Night position plate, and the alarm
relay is not in alarm, will it be possible to arm.

6.1.6 Using a VS A5 Floor Box
The VS A5 is designed to recess mount the detector in vault floors.
It may be used as a casting mold in new vault constructions. It may also
be used in existing vaults after cutting a hole in the vault floor.
The VS A5 features a heavy duty lid (1/5 inch thick) to accommodate
heavy loads that may exist inside bank vaults. The cable conduit inlets are
rubbersealed to preventwaterintrusion.

6.0.3 Wiring the VS A7 Keyhole Protection Kit
The Keyhole Protection Mounting Plate contains a microswitch that super-
vises the position of the lever.
The alarm loop should be wired in-series with the microswitch.
Whenthe lever covers the keyhole, the microswitch isclosedandthe sys-
tem can be armed.
If using an EOL, wire it to terminal six of the detector to connect it in-series
with the alarm relay and the microswitch.

7.0 Testing the Installation
7.0.1 Manual Tests
Check each installation for proper mounting and wiring.Apply power to the
detectors and connect an ohm-meter to terminals 4 and 5 of each detector
to ensure a closed alarm loop.
Perform the following tests:
•Scratch the protected surface directly around each de-
tector with a screwdriver. Depending on the strength of
the signal you generate, it may take 20 to 45 seconds to
generate an alarm. This test simulates an attack with a
drill or diamond disk.
•Strikefirmly with a hammer on the protected sur-
facedirectlyaroundeachdetector. Waittwosec-
onds between strikes. After five strikes, the
DS1520 will alarm. To protect the surface
from damage, use a small aluminum plate
between the hammer and the surface. This
testsimulatesanattackwithahammer and
chiselorhydraulicjack. Thistest isonly val-
id for the DS1520.
•Giveone powerful blow to the protected
surface directly around each detector.

testsimulatesanattackwithexplosives.
•Check the background signal level of the
detector. This will aid in determining what

•Replace the covers on the detectors. Check for a closed-loop condition
on the tamper loop.
•Connect the alarm and tamper loops to the control panel of the security
system. Perform a functional test of both the alarm and tamper signals
according the the panel specifications.
8.0 The Test System
8.1 The VS A14 Test Transmitter
This remote test system allows you to test the detectors by activating the
VSA14 Self-contained Test Transmitter.
The Test Transmitter is mounted inside the detector. It is activated by sup-
plying it with 12 volts. Upon activation, it will transmit signals that will alarm
thedetector.
•Mount the test transmitter inside the detector. Make sure it does not
touch the detector or mounting plate.
•The Test Transmitter has only two wires. A Red (+) lead and a Black (-)
lead.
-Refer to the following wiring example for installations with a Junction
Box.

8.2 The VS A15 Hand Held Test Transmitter
ThisTransmitterallowsyou to test the detector's range and functionality.
This testing accessory is required for all installations. This test must be
performed at all installations.
The VS A15 may be used with the DS1520 and DS1530 detectors or it can
be used with the VS A16 Movable Test Unit.
•TestingProcedure
-Hold the VS A15 to the protected sur-
face.
-Start the testing at the end of the pro-
tectionradius.
-Press the red button on the VS A15 to
activatethe alarm causing oscillations
(remember to hold the tester firmly against the protected surface).
-An alarm should occur within 45 seconds.
-If an alarm does not occur, move the VS A15 closer to the detector or
test unit.
-If an alarm does not occur at all, even while holding the VS A15 right
next to the detector or test unit, check the system wiring.
8.3 The VS A16 Movable Test Unit
The Movable Test Unit allows you to test the detector's range (range is
equal to a G ref setting) in conjunction with the VS A15 Hand Held Test
Transmitter. Make sure both units contain fully charged batteries.
The VS A16 is for use on steel or metal surfaces only.
The VS A16 mounts to the protected surface with a magnet in its base.
•TestingProcedure
-Placethe VS A16ontothe
protectedsurfacewherethe
real detector would go and turn it
on.The LED will come on steady.
-Activate the VS A15 Hand Held
Tester at the end of the protec-
tionradius.
-The LED on the VS A16 will turn
off within 45-60 seconds to sim-
ulate an alarm.
-If an alarm is not indicated, move
either the Test Unit or the Test
Transmitter until optimum cover-
age is verified.
