The table shows the input current taken by the various beacons.
A supply voltage variation of +/-10% outside the voltage range is permissible.
Nominal current at nominal voltage and 1Hz flash rate.
Max. rated current at worst case supply voltage and flash rate.
Table 1: Electrical Ratings
Ensure the system power supply is capable of providing the maximum current required for all beacons. Review associated cable
size, length and quantity of beacons on each circuit.
