Power supply check and calculation
Before proceeding to the system installation, it is necessary
to check the power supply of the whole system:
1. Check that the power supplies are enough to supply
the power current needed by the devices to install the
system;
2. Check that the distance (in meters of cable) between
power supply and devices allows the devices to get
enough power supply voltage to work correctly.
3. Maximum distance between Floor shunt and handset
Maximum distance = 50m (CAT5 Cable);
