MS-390 Single Head Motor Alarm | Industrial Continuous Sound Audible Alarm for Safety & Emergency

The MS-390 Single Head Motor Alarm is a robust industrial audible warning device engineered for reliable, long-lasting performance in critical safety scenarios. Built with a durable motor-driven fan blade sound source, it delivers a powerful continuous tone that cuts through noisy industrial environments, ensuring alerts are heard clearly across wide areas.

Composed of a precision-engineered sound source, auxiliary sound chamber, and rugged housing, this alarm is designed to withstand harsh operating conditions while maintaining consistent acoustic output. Unlike electronic alarms with selectable tones, the MS-390’s motor-driven mechanism produces a steady, unbroken warning sound—ideal for applications where a persistent, unmistakable alert is required to signal system failures, security breaches, or emergency situations.

This motor alarm is widely deployed across key industries: it serves as a vital safety component in security prevention systems, alerts operators to critical equipment malfunctions, enhances transportation safety by signaling hazards, supports medical rescue operations, and aids in emergency relief efforts during disasters. It can also be seamlessly integrated with compatible warning lights to create a high-impact audible and visual alarm system, maximizing visibility and audibility for comprehensive safety coverage.
