Description Of Terminal Boards - Urmet BiBus II ED. 1072/9 Manual De Instrucciones

The following elements must be considered for correct system construction:
• The surrounding electrical environment
• The wire type and cross-section area
• The extension of the system.
You are advised to arrange the wire passage hole in correspondence with a button module.

The terminal pin P1 is not present because the button is already connected inside the device.
SURROUNDING ELECTRICAL ENVIRONMENT
Construct the system respecting the safety standards. Avoid running bus wires (main station side bus and
door phone side bus) near power lines in the building, e.g. staircase lights, lifts, power line risers (230Vac).
A distance of at least 10 cm is recommended.
If wires must be laid near existing power lines, arrange a metallic partition in between, as commonly
employed in telecommunication system construction.
Important: No part of the BIBUS nd edition system must be connected to electrical earth.
WIRE TYPE
Use a normal one-pole wire with a suitable cross-section area for electrical connections. Multiple pole wire
must not be used. The main push-button panel side bus and the door phone side bus must run in separate
conduits. Coupler spines (where fitted) must run in reciprocally separate conduits.
Telephone wire terminals L1 and L2 with a diameter exceeding 0.6 mm (AWG22) can be used for distances
less than 100 metres between calling station and bus coupler, or between bus coupler and most distant
door phone.
MAXIMUM DISTANCE BETWEEN DOOR PHONE SYSTEMS
The maximum connection lengths and the respective cross-section areas of the wires L1, L2 are shown in
the following table.
