mis-wired.
— If the distance between the building distributor and the Multi-Entry Panel is within
20m, the power is supplied from the building distributor.
If the distance between the building distributor and the Multi-Entry panel is greater
than 20m, a separate power source (RF-1A for Audio-type Multi-Entry Panels) is
required. The maximum extended distance range cannot exceed 100m. (In the case
of using a separate power source, there is no power line connection between the
building distributor and the Multi-Entry Panel units)
