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
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.
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
cash boxes.
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.

6.02 Tools Required
The following tools will be needed during the installation:
• The VS A1 Mounting Plate (also can be used for the drilling pattern).
• A power drill (with a hammer facility for concrete or brick).
• A high speed steel drill bit, # 29 (for 8/32 tap) [(3.3mm for M4 wire tap)].
• A high speed steel drill bit, 1/2 inch (12mm).
• A concrete drill bit, 1/2 inch (12mm) (for the expansion plugs).
• An 8/32 tap (M4 wire tap) (to mount the VS A1 mounting base to steel
surfaces).
• Oil to cool the drill and wire tap during steel mountings.
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.
• Mounting
See the following figure for the specific mounting holes to use during each
installation. The plate must be mounted so the counter-sunk holes face
away from the mounting surface.

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 mark-
ing 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 con-
crete. 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
cut-out of the mounting plate).
Note: Make sure that when the Tester is mounted, it will not be in contact
with the mounting plate.
- Drill out the hole for the expansion plug.
- Use a 1/2 inch (12mm) drill bit.
- 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 con-
crete. 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 Tester into place. Make sure it does not come in contact with
the mounting plate.
6.04 Mounting the DS1520/DS1530 Directly onto Steel
In some installations it is recommended that the detector be mounted di-
rectly onto the steel surface.

Mounting
Holes
• 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.
