YUMO MS‑390 High‑Power Motor‑Driven Siren, Safeguard Industrial Site Safety

In various working scenarios of modern industrial production and engineering construction, reliable audible warning acts as a vital barrier to protect personnel and equipment. Ordinary piezoelectric buzzers have limited volume and weak sound penetration. Their sound is easily overwhelmed by machine roars and site noise, failing to give effective alerts in open and complicated places such as mines, construction sites, large workshops and docks. YUMO MS-390 motor-driven wind siren is developed for high noise harsh working conditions to make up for the shortcomings of traditional alarm components.

Adopting motor-driven wind-screw structure, it produces loud 120-130dB alarm sound with long transmission distance. Warning signals can be clearly heard even in noisy workshops. Equipped with metal main body and heavy-duty protective housing, it reaches IP44 protection grade, dust-proof, splash-proof and shock-resistant. It runs steadily under wide temperature range from -20℃ to +65℃ and copes with dusty and humid environments.

Multiple voltage options like AC220V and AC110V are available to fit most industrial power supplies. It triggers alarm immediately after power-on with no extra controller required. Simple wiring and wall-mount installation bring low-maintenance cost. Stable operation avoids jamming for long service life. It is widely used for machine fault alarm, production-line emergency notice, construction-site safety reminder and factory emergency alert. Strictly tested and CE certified, it is a cost-effective audible alarm option for industrial safety systems.
