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.
