GENERAL RULES FOR INSTALLATION
Power supply check and calculation
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).
Before proceeding to the system installation, it is necessary to check the power supply of the whole system:
