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 con-

Range

struct the vault, safe or ATM, 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 vault door. The detectors should be surface or recess mounted, and placed high enough to keep clear of safes, document cabinets, and deposit boxes.

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).

4.1.2 Range Guidelines for Safes and ATMs

N/R = Not recommended

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.

1. Mounted fixed, close to the hinge providing a short distance to the junction box.

2. Mounted on the key-hole protection plate to cover the key-hole. In the armed position, the lever will cover the key-hole. Connect the lever contact 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 prevents 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.

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.

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:

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.

5.2 Planning Protection of

no alarm and tamper switch closed

an ATM Unit

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

6.03 VS A1 Mounting Plate

The VS A1 is a Mounting Plate that can be used to mount the DS1520 and DS1530 onto steel or concrete surfaces. Whenever the detector is to be mounted on concrete, the VS A1 must be used.

• Use the bolts provided. You will have to drill and tap the mounting holes.

• Define the exact location of the detector.

• Use the detector as a template and mark the location of the three holes to be drilled.

- These are the holes that will hold the DS1520/DS1530 to the steel

surface.

• Drill out these three holes with a # 29 drill bit in a high speed drill.

- Drill the holes at least 1/4 inch deep.

• Thread these three holes with a 8/32 tap.

- Use a little oil to lubricate the tap while threading the hole.

- After threading the holes, use a 1/2 inch drill bit in a high speed drill to smooth the surface around the holes and to remove burrs.

• Mount the detector to the surface using the three 8/32 screws provided.

• If a VS A14 Test Transmitter is to be used, it may be installed in the detector’s right-hand bottom corner at this time.

• Mounting:

- See the diagrams below.

6.1 Indirect Mounting of the DS1520/DS1530 to

Steel

In some installations, indirect mounting of the detector is recommended:

• Use the VS A4 mounting plate when welding

to steel.

• Use the VS A6 for Day/Night applications.

• Use the VS A7 when keyhole protection is required.

6.1.1 Indirect Mounting to Steel Using the VS A4

• Clean the mounting area of any paint or other surface finish.

• Place the VS A4 on the mounting surface.

- Make sure it can not move during the welding process.

• Weld the VS A4 to the mounting surface.

- 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 lubri-

cate 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.

6.1.3 Using the VS A7 Keyhole Protection Kit

The VS A7 is designed to cover the keyhole with a hardened steel lever when in the Night (armed) position. This will stop an intruder from using plasticine explosives on the keyhole.

The kit includes the following:

• Mounting

- 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.

A= Bolt to open the VS A7 B= Mounting Holes C= Wire channel for the microswitch D= Release Lever E= Keyhole protection lever

- 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 lubri-

cate 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 re-

lease lever, the keyhole protection lever, and the microswitch.

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.

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.

We ld rods to

re inforcem ent bars

- 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.

6.1.5 Surface Mounting with the VS A3

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.

The kit includes the following:

- eight core cable, 6.6 feet (2 m) long

- flexible stainless steel conduit

- protective ferrules

- cable strain reliefs

- cable clamp bolts

- plastic cable entry for two conduits (VS A13)

• The protective ferrules are used on the two ends of the steel conduit. This will protect the cable from the sharp edges.

• The steel cable strain reliefs are used to secure the conduit within the detector (replace the plastic strain relief on the detector with the steel one).

• The plastic cable entries fit in the cover of the detector. The two holes are made to fit the stainless steel conduit. A third knockout is available if needed.

5.1.8 Using the VS A10 Junction Box

The VS A10 is a tamper resistant Junction Box. It has a hardened steel

insert within the cover to protect it from drilling; it has a sabotage contact to protect it from being opened or removed from its mounting surface.

It contains two lines of connections on a PC board with a total of 32 terminals.

• Mounting

- If using an end of line resistor (EOL), use terminal 6 of the detector to put the resistor in-series with the alarm relay.

- To put both of the Movable Mounting Plate's switches in-series, connect the wire from the microswitch to terminal 4 of the detector.

- Connect the alarm loop from the Junction Box to the center terminal of the VS A6 and to terminal six of the detector (if not using an EOL, connect it directly to terminal five).

6.0.3 Wiring the VS A7 Keyhole Protection Kit

The Keyhole Protection Mounting Plate contains a microswitch that supervises the position of the lever.

The alarm loop should be wired in-series with the microswitch. When the lever covers the keyhole, the microswitch is closed and the 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 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:

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. 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

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.

• Testing Procedure

VS A16

- Place the VS A16 onto the 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.
