The LONDON control panel allows a maximum of 10 repeaters to be connected by means of a 4-wire 1.5 mm2 connection (two power supply wires and two communication wires for the RS485 line). The two wires of the RS485 line will be connected from the back panel of the control panel to the back panel of the corresponding repeaters.
The two power supply wires shall be connected from the 30V output of the control panel power supply to the back panel of the corresponding repeaters.
Up to 3 repeaters are powered from the 30V output of the London control panel power supply.
To power 4 to 10 repeaters, it must be done from the 30V output of an external power supply (FAE).
The connection of the repeaters, both communication cables and 30V power supply cables will be made with 2 x 1.5 mm2 twisted and shielded halogen-free cable, up to a maximum cable length of 1200 metres.
