Hand Operated Siren


The hand-operated siren is intended to provide effective warning in applications without power, such as campsites, civil defense, mountain rescue, and coast guard warning. This siren is powered by rotating the handle and has a plate that shuts off the sound once it reaches full speed, allowing it to produce three different tones. The siren is tough and compact, and it folds up to a small size for easy transport to remote locations.
