Alarm Whistle from England

The characteristic siren howling can be easily generated with this portable alarm whistle. Since the swelling and decreasing of the signal tone can be modulated in a wonderful way, the attention can be attracted quietly as well as loudly and assertively. 
The siren sound of this small, robust whistle sustains for a surprisingly long time. Thus this whistle is not only suitable as a signal or emergency whistle, but also as a musical instrument with which you can create varied sound effects.
The whistles of ACME convince us by their first-class quality as well as the sustainable and durable materials.
