Prox Mifare Series (Teardrop)

Before you Begin

Unpack the Prox Mifare Series (Teardrop) reader and check the shipment
contains the following items:

• 1 x Prox Mifare Series (Teardrop) reader base

• 1 x Prox Mifare Series (Teardrop) reader facia

• 1 x printed circuit board (PCB) assembly

• 1 x cable assembly

• 1 x M3 Torx Post Security screw

Installation Note

CAUTION
This equipment contains components that can be damaged by
electrostatic discharge. Ensure both you and the equipment are
earthed before beginning any servicing.

Firmware

• 4 x self tapper pozi counter sunk fixing screws (two different lengths)

WARNING: You must use the screws provided, as using other types of
screws could interfere with the electronics. (See the “Mounting” section
later for further explanation.)

Version vMT3.07 (or later) of the Prox Mifare Series (Teardrop) reader
firmware code supports the Mifare Enhanced Security feature. This feature
provides a method of ensuring that readers reading Mifare cards are able to
prevent access through the use of replicated cards, and is optional for
customers, (i.e. customers can choose whether to use this enhanced security
and which doors to apply it to).

The Mifare Enhanced Security feature is only supported when the reader is
connected to a Cardax FT Controller 3000 or a Cardax FT GBUS Universal
Reader Interface.

Power Supply Requirements

Power for the Prox Mifare Series (Teardrop) reader is usually taken from the
incoming supply of the device to which it is connected. That is, from the:

• Cardax FT Controller 3000-4R

• Cardax FT Controller 3000

• Cardax FT GBUS Universal Reader Interface (Cardax FT GBUS URI)

The supply at the reader should be 13.6 Vdc ± 15% (between 11.5 and 15.6
volts) It is recommended that the voltage should be between 12 and 15 volts to
allow for local installation and environmental conditions, to ensure reliable
operation.

The power source for Prox Mifare Series (Teardrop) readers should only be
linear or good quality switched mode power supplies. The performance of the
reader may be affected by a low quality, noisy power supply.

Cabling

The Prox Mifare Series (Teardrop) reader uses the Cardax IV communications
system. The reader cable entry grommet is designed to accept 4 core, 0.2mm2
(24 AWG) cable. This cable has an outside diameter of 5mm (1/5 inch). A
short tail of this cable is supplied with connector fitted, with each reader.
When using a single cable to carry both power supply and data from the source
to the reader, both the power supply voltage drop and data requirements must
be considered. The cable uses two wires for data and two wires for power
supply.

Power: The conductor size should be sufficient to ensure that the voltage at the
reader terminals is not less that 12 Vdc.

Data: The capacitance between any conductors or any conductors and the
shield should not exceed a total of 24nF for the entire cable. A twisted
pair is recommended for the data circuit.

It is recommended that the distance between the control unit and the reader
should not exceed 200m (600ft).

Choosing a cable

The cable chart below lists cable sizes and the maximum length for connecting
a single Prox Mifare Series (Teardrop) reader to a Controller and power
supply.

Cable type Maximum distance *

CAT 5 ** 40m (130 ft)

4 x 0.2mm2 (4 x 24 AWG) 40m (130 ft)

4 x 0.5mm2 (4 x 20 AWG) 100m (330 ft)

4 x 1mm2 (4 x 18 AWG) 200m (660 ft)

* These distances apply to unshielded cable. If shielded cable is used, the
distances will be reduced due to the increased capacitance caused by the
shielding.

** CAT 5 is not recommended for security systems as this cable has solid
copper conductors and is designed for use with RJ45 insulation displacement
connectors.

Distance between Proximity Readers

The distance separating any two proximity readers must not be less than
200mm in all directions.

200 mm

Mounting

When mounting a proximity reader on an internal wall, check that any reader
fixed to the other side of the wall is not less than 200mm away.

Note: The Prox Mifare Series (Teardrop) reader has been designed to metric

specifications. Therefore any imperial measurements provided are
approximate only.

The Prox Mifare Series (Teardrop) reader is designed to be mounted on any
solid flat surface. However installation on metal surfaces, particularly those
with a large surface area will reduce read range. The extent to which the range
is reduced will depend upon the type of metal used. To minimise this effect,
plastic spacers which may be mounted between the reader and the metal
surface are available (Part number C190980). Please contact your local Cardax
dealer for more information.

Note: The grommet through which the cables feed into the base of the Prox

Mifare Series (Teardrop) reader helps to keep the unit waterproof.

Using the mounting dimensions on the back of this Installation Note as a guide,
drill a 20 mm (3/4 inch) diameter hole for the base extrusion through or into the
mounting surface to a minimum depth of 40 mm (11/2 in).

Drill two pilot holes for the fixing screws.

Run the building cabling through the base and grommet.

Fit the base to the 20 mm (3/4 inch) hole and secure it to the mounting surface
using two of the fixing screws provided.

Note: The surface the reader is being attached to will determine which length

screws are most appropriate from those provided.

WARNING: You must use the screws provided, taking care not to over­tighten them. Make sure that the heads of the counter sunk screws are flush
with the top of the holes in the base, and ensure there is clearance for the screw
that closes the base and facia together.

Failure to do this, and/or using other types of screws could interfere with the
electronics.
