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.
Nominal current at nominal voltage.
Table 1: Electrical Ratings.
It is important that a suitable power supply is used to run the equipment. The power supply selected must have the necessary capacity
to provide the input current to all of the units.
The above table shows the input current taken by the various sounders and shows the maximum voltage at which the sounders can
be operated:
The input current will vary according to the voltage input level and the frequency of the tone selected.
