The table shows the input current taken by the various sounders.
Supply voltage variation of +/-10% outside the voltage range is permissible.
The current levels shown above are for the 440Hz Continuous tone @ nominal input voltage.
Nominal current at nominal voltage and 1Hz flash rate.
Max rated current at worst case supply voltage.

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.
