The LONDON control unit allows up to a maximum of 10 repeaters to be connected, via a 4-wire connection of 1.5 mm2 (two alligation and two communication for the RS485 line). The two wires of the RS485 line will be connected from the back panel of the control unit to the back panel of its corresponding repeaters.
The two power wires will be connected from the 30V output of the power supply of the control unit to the back panel of its corresponding repeaters.
Power up to 3 repeaters is performed from the 30V output of the London power supply.
To power 4 to 10 repeaters must be performed from the 30V output of an external power supply (FAE).
The connection of repeaters, both communication and 30V power cables, shall be carried out with a 2 x 1.5 mm2 cable twisted and shielded halogen-free, up to a maximum cable length of 1200 meters
