motor siren radius 0.5km

The Motor Siren with 0.5km range is a compact electromechanical warning device suitable for small factories, workshops, schools, farms, and residential compounds. It produces a loud wailing tone audible up to 500 metres, providing effective notification for shift changes, break times, security alerts, and emergency evacuations within a localised area. The smaller motor and horn assembly make it lighter and easier to mount than larger industrial sirens, while still delivering a piercing sound that cuts through normal background noise. Operates on mains power via a simple switch, timer, or alarm system trigger. Durable metal construction ensures reliable outdoor service.
