Introduction
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.
A wireless system always comprises a PC, the
OMEGA software, a number of Access Points for

data exchange and at least one locking device.
A cable 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 or a optional RF-Stick and a
Windows™ PC (such as a netbook) with the OMEGA software (see
also page 24, "Programming with the OMEGA software").
The wall terminals signal their status by one red and one green
LED and a piezo-electric beeper.
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
