Note: The maximum length (in metres) of any individual wiring run = 100 divided by the number of stations on the run.
i.e. The maximum length for the cable run connecting Rooms 1, 4,5 & 6, is
100m ÷ 3 room stations = 33 metres in total.
(Room 1 is not used in the calculation because it is the station to which the power supply is connected)

Note: The maximum length (in metres) of any individual wiring run = 100 divided by the number of stations on the run.
i.e. The maximum length for the cable run connecting the Door station and Rooms 1,2 & 3, is
100m ÷ 3 stations = 33 metres in total.
(Room 1 is not used in the calculation because it is the station to which the power supply is connected)
A Load Resistor is required on Room Station Only systems. In the examples
above, the Load Resistor should be fitted across the VLC and NEG terminals
of Room 1 (the Room Station to which the power supply is connected).
