Introduction

Introduction

Description

The wall terminals are part of the OMEGA system. This system
component performs the function of physical access control.
Wall terminals are used at locations, where a locking cylinder
cannot be used for this purpose.

Examples for the use of wall terminals include automatic sliding
doors, barrier systems, drive-in controls, rolling and sliding
gates, door systems equipped with the CEMO system, etc. The
OMEGA system is also suitable for door systems already
including a door opener (retrofitting). Also installation in
electrical equipment with controlled access (e.g. copying
machines) is possible.

Wall terminals cyclically send inquiries to scan for the presence
of an authorized locking medium within a range of up to
50 mm. If an authorized locking medium is found, the wall
terminal opens within 300 ms.

All Mifare transponder media and media according to ISO
14443A and DESFire EV-1 can be programmed at the wall
terminal and used as authorized locking media.

The wall terminals are available in two types for different
purposes of use:

 WT-M-I is designed for indoor use and contains the reader

module and the control unit in a single housing.

 WT-M-II is designed for use in high-security applications.

The reader module is fitted in the unprotected outside area,
while the control unit is installed in the secured interior. You
can decide whether the WT-M-II only reads outside or both
inside and outside.

With the WT-M-II wall terminal, the control unit can be
installed at a maximum distance of 20 metres away from the
reader module. The connection between the reader module
and the control unit is established with commercial cables.

Introduction



A wireless system always comprises a PC, the
OMEGA software, a number of Access Points for
data exchange and at least one locking device.

In all other respects, the functionality of the WT-M-II is the
same as that of the WT-M-I wall terminal.

The wall terminals can be operated as stand-alone devices or
within a wireless system controlled by the OMEGA server. For
operation within a wireless system, the wall terminals have a
radio frequency (RF) interface for the permanent
communication with locking media and Access Points of the
OMEGA series.

For stand-alone operation, the wall terminals do not require
any additional devices or connections. The wall terminals are
not connected to any other devices, either.

In RF mode, the wall terminals receive the programmed
authorizations via their RF interface and feed event data such
as log files of door opening and closing operations back to the
server.

Thanks to its structure, a wireless system combines a high
level of operating convenience with low administrative
expense. It also reduces personnel expenses since virtually no
time is lost by going to the wall terminals for on-site data
maintenance and programming.

An RS 232 interface is provided to upload new software into
the wall terminals. Connection is easy with the optional
programming cable.

While new system software is uploaded via the cable interface,
communication over the RF interface is interrupted.

The wall terminals can also be programmed on site using an

optional programming cable and a Windows™ PC (such as a

netbook) with the OMEGA software (see also page 16,
"Programming with the OMEGA software").

The wall terminals signal their status by one red and one green
LED and a piezo-electric beeper.

OMEGA Mifare wall terminals 11

Introduction



For further information, please refer to the
OMEGA system Programming Instructions which is
available free of charge at www.ces.eu.

The wall terminals can be fitted either directly on in-wall switch
boxes or using the supplied fitting frame.

The wall terminals may not be fitted directly on metal surfaces
because the sending and receiving frequencies of the reader
will be detuned by the magnetic properties of the metals.
Depending on the metal material, the reading range of the wall
terminal may be reduced to as much as zero.

For fitting on a metal surface, always use the supplied fitting
frame.

OMEGA Mifare wall terminals 13

Introduction

Optional Master media

Optional Master media allow you to set additional functions
manually without requiring additional aids such as a PC or
programmer.

SYSTEM-MASTER

The SYSTEM-MASTER grants all authorizations on the highest
level. For each locking system, there is one and only one valid
SYSTEM-MASTER.

With the SYSTEM-MASTER, you can authorize up to ten
PROGRAM-MASTERS. In its basic version, a locking system
requires one SYSTEM-MASTER and one PROGRAM-MASTER
each to program your wall terminals. The SYSTEM-MASTER is
also used to authorize the following additional Master media for
your wall terminals:

 TIME-MASTER

PROGRAM-MASTER

The PROGRAM-MASTER is used to authorize and delete the
authorization of your locking media.

14 OMEGA Mifare wall terminals

Introduction

TIME-MASTER

With the TIME-MASTER, you set the opening time of your wall
terminals. During the opening time, the wall terminals allow
free access.

 The opening time is the period during which the relay is

pulled up.

When the access terminal detects a TIME-MASTER, it starts
beeping at one-second intervals. The number of beeps
determines the opening time.

OMEGA Mifare wall terminals 15

Introduction

Mifare locking media

 To perform the locking or unlocking operation, hold your

authorized locking medium in front of the reader. The
maximum distance is 50 mm.

The green LED in the wall terminal goes on to signal enable
status and the connected door system opens.

During the set opening time you can pass through the door.
During this opening time, the wall terminal does not respond to

any other locking media.

Operating the wall terminal

DESFire EV1 Transponder (locking media)

You use DESFire EV-1 locking media in two different modes:

DESFire EV-1 in security mode (optional)

Locking devices and locking media operating in the security
mode (1) are manufactured exclusively by CEStronics and
programmed with individual keys and special firmware.

The data transmission between the locking device and the
locking medium is encrypted. Only locking media that are
authenticated by the device are authorized to lock or unlock.

This ensures a very high protection against manipulation.
These locking devices (1) will not accept any foreign

transponders (2); they do not respond to any locking or
unlocking attempt with other locking media.

A DESFire EV-1 locking medium manufactured by CEStronics
operating in the security mode can be used in other systems
(3) requiring this type of transponder.

This ensures the multi-application capability of the locking
medium.

44 OMEGA Mifare wall terminals

Operating the wall terminal

DESFire EV-1 in standard mode

Locking media operating in the standard mode behave like any
other ISO 14443 transponders. For authorization, the UID of
the locking medium is used.

If you manage your systems with the CEStronics software, you
can use both DESFire EV-1 variants with the CEStronics
software.

 Move your authorized locking medium (1) into the reading

range of the wall terminal. This distance is about 50 mm.

The reader module (2) identifies the locking medium. The wall
terminal sends a short signal to signal the enable status.

During the opening time you can open the door. During this
opening time, the wall terminal does not respond to any other
locking media.

If you are using a locking medium that is not authorized to
enable this locking cylinder, the light ring of the locking
cylinder flashes red four times and you hear four successive
beeps. In this case, the outside knob is not coupled with the
follower. The outside knob rotates freely but the door lock
cannot be operated.
