Detectors, Bells. Human Activity may also be a factor.
4.1 Range
The range of the detector is dependent on the sensitivity setting of the detector 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 attack, any gaps or cracks in the material will result in reduced performance of
the detector.
First, it is necessary to determine the maximum range of
the detector, based on the type of material used to construct the vault, safe or ATM, then the number of detectors
required for the installation can be determined.
Range
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 Range Guidelines for Safes and ATMs
A single detector may be used to protect a safe or ATM if no one wall or side
of the safe or ATM exceeds 4 feet (1.2m) across or high. Otherwise, use the
chart below to determine the maximum detection radius [listed in feet
(meters)] which will provide sufficient coverage of the entire unit to be protected. The ranges shown are guidelines only -- it is important that the operation of the detectors be verified by testing after installation.

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).
5.0 Planning the Installation - General Considerations
The detection ranges shown in this guide are intended as guidelines for
ideal installation conditions. Actual detection range may be affected by
situations such as partitions inside the safe and non-continuous surfaces in
the safe’s construction. 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
If mounting inside the body, mount a detector on a space which is clear and
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.
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,
mount the detector on that drawer. Mount the night position plate on the drawer and the day position plate on
the side of the cabinet.
If mounting outside the body, mount a detector on a wall at the same height
as the the detector to be mounted on the door. The detector on the door may
be mounted in one of three ways:

Displ ay
Typically, the door is the only exposed side
of the safe used in an ATM unit. When this
is the case, an attack is most likely to occur
against the door, therefore the detector
should be mounted on the door for maximum
protection. Otherwise, the protection is
planned the same as for a safe.

6.0 Installation
6.0.1 The Detector - Location of Major Items
The DS1520/DS1530 consists of a cast aluminum housing, with outside
dimensions of 3 x 3 3/4 x 1 inch (w, h, d) (8 cm x 10 cm x 3 cm), and a weight
of 10.2 ounces.
Removing the cover screws (2) and the cover from the base plate gives
access to the connection terminals, sensitivity adjustment control, and the
main mounting holes as shown in the following drawing below.
A = Holes for mounting the detector
B = Hole for mounting the plate to the concrete expansion plug
C = Hole for marking the mounting hole for the VS A14, if used. After the
plate is mounted to the surface, rotate the plate 180°, and using the “C”
hole, locate the spot for drilling the hole. Reposition the plate after marking the spot.
Define the location for the VS A1.
- Mark the location for the Plate's expansion plug.
- Using a 1/2 inch (12mm) drill bit, drill out the hole for the expansion
plug.
- Drill the hole at least 2 1/4 inches (6cm) deep. If the surface finish is
thicker than 1/2 inch (12mm), drill the hole deeper.
- At least 2 inches (5cm) of the expansion plug should be in the concrete. Longer bolts may be needed.
- Place the expansion plug into the concrete.
- Make sure the top end of the plug does not stick out of the concrete.
- Bolt the mounting plate into place. Do not completely tighten yet.
- If used, mark the location for the Tester's expansion plug (lower right

- Drill out these three holes with a # 29 (3.3mm) drill bit in a high speed
drill. Drill the holes at least 1/4 inch (7mm) deep.
- Thread these three holes with a 8/32 (M4) tap. Use a little oil to lubricate the tap while going through the hole. After threading the holes,
use a 1/2 inch (12mm) drill bit or countersink in a high speed drill to
smooth the surface around the holes and to remove burrs.
- Mount the Night plate with the three bolts provided.
- Define the location of the Day position plate. Use the three screws and
anchors provided.
- Mount the detector to the moveable mounting plate.
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.
6.1.3 Using the VS A7 Keyhole Protection Kit
The kit includes the following:
- A magnetized mounting plate, to adhere to two smaller plates.
- The two smaller plates. These two plates are called the Day (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 Junction 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
mounting surface to guarantee proper connection.
• The Moveable Mounting Plate contains a reed switch and a 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.

- Define the location of the VS A7 on the mounting surface.
- Remove irregularities on the mounting surface to guarantee proper
connection.
- Mark the mounting holes “B”. Prepare to drill and tap the holes.
- Drill out these three holes with a # 29 (3.3mm) drill bit in a high speed
drill. Drill the holes at least 1/4 inch (7mm) deep.
- Thread these three holes with a 8/32 (M4) tap. Use a little oil to lubricate the tap while going through the hole. After threading the holes,
use a 1/2 inch (12mm) drill bit or countersink in a high speed drill to
smooth the surface around the holes and to remove burrs.
- Mount the VS A7's backplate to the mounting surface.
- If more space is needed to get the steel lever over the keyhole, VS A8
spacer plates may be used.
- When done, always mechanically test the proper function of the release lever, the keyhole protection lever, and the microswitch.
To make the box weather resistant:
• Apply silicone insulation to all joints, mounting hardware, and holes.
• After the detector and box have been mounted and tested, apply silicone
insulation around the edges of the box lid and cover before and after it
has been secured.
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
rubber sealed to prevent water intrusion.
6.1.4 Recess Mounting with the VS A2
The VS A2 is designed to recess mount the detector in concrete walls.
Preferably, the recess box should be molded into the wall during construction of the vault.
• Define exactly where the locations of the detectors will need to be (do not
forget floors and ceilings).
- Make arrangements with the construction crew to be on-site when they
put up the concrete casting shutters (wooden panels).
- At the predetermined mounting sites, drill two holes in the wooden
panels.
- Mount the recess box to the wooden panels using the two threaded
rods provided for each installation.
- Fasten the bracket in the tapered hole in the back of the mounting box.
Weld Brackets to
reinforcement bars
To ensure proper detection, weld the VS A5 to the reinforcement bars
within the concrete. This is done by mounting the L-shaped flat iron rod to
the bottom of the mounting box, then welding this piece to the reinforcement rods.

5.1.7 Using the VS A9 Armored Cable Kit
The VS A9 is designed to be used as a protective transfer of cable from the
door of a safe/vault to its body or an adjacent wall. It should be used together with the VS A10 Junction Box.
- Weld the bracket to the reinforcement rods for the concrete.
- Run conduit to the holes on the sides of the mounting box.
- Attach the conduit to the reinforcement rods. This will prevent them
from shifting or falling out during pouring of the concrete.
- Seal the holes around the conduit and any hole not being used. This
will prevent concrete from running into the box.
- After the concrete has been poured and VS A2 recess box is accessible again, mount the detector on a VS A1 mounting plate, then mount
the assembly inside the box.
The VS A3 is a box designed to protect the detector from damage and
excess humidity.

DS1520/30 Installation Instructions
7.0 Testing the Installation
Grou nd
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 detector 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.
• Strike firmly with a hammer on the protected surface directly around each detector. Wait two seconds 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
test simulates an attack with a hammer and
chisel or hydraulic jack. This test is only valid for the DS1520.
• Give one powerful blow to the protected
surface directly around each detector.
The detector will alarm immediately. This
test simulates an attack with explosives.
• Check the background signal level of the
detector. This will aid in determining what
+
ambient noise may cause nuisance alarms.
Connect a DC volt-meter to terminal 2 and
the test point of the detector. Put the meter
in the 3 or 10 volt range. Make sure all possible causes for ambient noise/vibrations
are present and operating. Check the output voltage and refer to the
following chart:

VS A14
8.2 The VS A15 Hand Held Test Transmitter
This Transmitter allows you to test the detector's range and functionality.
This testing accessory is required for all installations. This test must be
performed at all installations.
8
Preferably, the source of ambient noise should
be removed first. If this is unsuccessful, then
the range should be reduced.
The VS A15 may be used with the DS1520 and DS1530 detectors or it can
be used with the VS A16 Movable Test Unit.
• Testing Procedure
- Hold the VS A15 to the protected surface.
- Start the testing at the end of the protection radius.
- Press the red button on the VS A15 to
activate the 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
• 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.
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.
8.0 The Test System
The VS A16 mounts to the protected surface with a magnet in its base.
8.1 The VS A14 Test Transmitter
This remote test system allows you to test the detectors by activating the
VS A14 Self-contained Test Transmitter.
The Test Transmitter is mounted inside the detector. It is activated by supplying it with 12 volts. Upon activation, it will transmit signals that will alarm
the detector.
• 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.
- Refer to the examples on the previous pages for other wiring options.
DS1520/30 Installation Instructions
• Testing Procedure
VS A16
- Place the VS A16 onto the Movable Test Uni t
protected surface where the
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 protection radius.
- The LED on the VS A16 will turn
off within 45-60 seconds to simulate an alarm.
- If an alarm is not indicated, move
either the Test Unit or the Test
Transmitter until optimum coverage is verified.
