System information
The Gira door communication system operates with the volt-
age type SELV.
With the audio control device, systems with up to 70 audio
devices can be realised in certain systems, e.g. 1 built-in
speaker with 5 add-on modules and 68 surface-mounted
hands-free feature home stations.
Depending on the system size, a maximum of 3 home stations
can be operated in parallel per call button
A call-tone differentiation is made between the following calls
at the home stations:
• door call (initiated by call button)
• floor call (initiated by floor-call button)
• internal call (initiated by call button for home stations)
Cabling and cable arrangement
Cables with a wire diameter of 0.6 or 0.8 mm can be used as
bus lines.
The following cable types are suitable for use as bus lines:
• J-Y(ST)Y (communication line)
• YR (insulated bell wiring)
• A-2Y(L)2Y (communication cable)
