The FK234 is another in the series of emergency vehicle sounders, suitable for class room practical soldering sessions and examination of transistors in simple tone generation circuits. The output sound, through the supplied 8 Ohm 0.25W speaker, is similar to the police vehicles siren in many countries, so the FK 234 would be an ideal sound effect unit for stage, models and toys.
