The table shows the input current taken by the various sounders.
The current levels shown above are for the 440Hz Continuous tone @ nominal input voltage at P2 and P3 power setting.
Nominal current at nominal voltage.
Max rated current at worst case supply voltage.
Table 1: Electrical Ratings.
Ensure the system power supply is capable of providing the maximum current required for all sounders. Review associated cable size,
length and quantity of sounders on each circuit.
