Device description
The DCS repeater is an active component for expanding a
Gira door communication system. It is for range extension
and for increasing the number of devices. The DCS repeater
amplifies audio and data signals of the door communication
system in both directions.
In systems with video function, the DCS repeater performs
the function of a video amplifier: The DCS repeater
increases the volume of the incoming video signal at the
"Bus In" input to the maximum permissible bus volume and
outputs it at the "Bus Out" output. In doing so, line
attenuation from the source of the video signal to the input
of the DCS repeater is compensated.
Each line segment requires its own control device, and the
DCS repeater counts as one device in each of both line
segments.
Depending on system size, the DCS repeater can be
operated in 2 different operating modes:
Repeater mode
In "Repeater mode" the DCS repeater interconnects 2 line
segments so that the number of devices in a video or audio
door communication system and cable range can be
doubled.
A second control device is needed for supply of the second
line segment.
Multi-conversation mode
In "Multi-conversation mode" the complete system is
subdivided into several lines (1 main line, up to 5 ancillary
lines) interconnected via the DCS repeater. Each line is
supplied by its own control device.
A total of five DCS Repeaters can be used in one system in
Multi-conversation mode.
In "multi-conversation" operating mode, incoming calls are
forwarded to the ancillary line when required with the aid of
a filter table automatically generated during start-up. Thus,
according to topology, it is possible to conduct multiple
conversations in one complete system. However, it must be
considered that only one conversation can be active for
each line.
A conversation from the main line to a non-assigned
ancillary line is also possible with an already existing
conversation in another ancillary line. Similarly, internal
conversations can be conducted between two unassigned
ancillary lines if the main line is not assigned.
Mounting
For installation protected from dripping and sprayed water,
the DCS repeater control device is mounted on a top-hat rail
in the distribution.
Connection terminals
Connection to the Gira 2-wire bus is with plug terminals.
Bus In
Connection for the incoming signal of the Gira 2-wire bus.
Bus Out
Connection for the outgoing signal of the Gira 2-wire bus.
The video signal is forwarded in amplified state via Bus Out.
Door opener on main and ancillary lines
If a system requires several door openers, only the door
opener function of the control device on the main line can
be used. All other door openers must be controlled using
switching actuators.
Start-up
Start-up of the door communication system is identical to
start-up of Gira door communication systems without a
repeater.

Integrating a door station in an ancillary line
If a door station is to be integrated into an ancillary line,
this must be connected to the control device via a video
multiplexer.

Important
Installation and mounting of electrical devices may only be
carried out by a qualified electrician.
Equipotential bonding
In door communication systems installed over several
separate buildings, sufficient equipotential bonding must
be ensured between control devices.
i
Video signal direction
The video signal in the DCS repeater is forwarded only in
one direction from Bus In to Bus Out.
Separate cable routing
Cable feed to Bus In and Bus Out must be in separate
cables.
i
Activating programming mode
For start-up, programming mode is only activated on the
control device of the main line.
