International signal tones for the widest possible range of applications
The Ex-multi-tone sounder 714 provides 26 different tones and frequencies for a wide range of signalling applications – from indicating a safety status to signalling extreme dangers. The different tones can be set using DIP-switches. Two sound output can be set externally via voltage inputs.
