This sounder comes in two different versions: a base sounder and a standalone model. The inte-grated electronic tone generator can output 11 different tones (including DIN tones conforming to DIN 33404 and EN 457). They include various wailing tones, fire alarm signals, etc. Depending on the operating voltage and the set tone and volume, the sound intensity varies between 87 and 100 dB(A).
The tone and volume are set using an integrated DIP switch and a flexibly adjustable potentiometer.
