Description
Motor Siren MS-490 is a compact, robust, electromechanical audible warning device designed for applications requiring a clear, powerful, and penetrating sound over short to medium distances. As an electromechanical siren, it relies on the physical rotation of an electric motor and an impeller/rotor to generate sound, which results in a distinct, high-volume tone that is effective even in noisy environments.
Features:
- Electromechanical Operation: Features an electric motor that rapidly rotates an air-chopping mechanism (rotor/impeller) inside a fixed stator. The high-speed alignment and misalignment of ports create pressure pulses that generate the signature loud, penetrating sound.
- Distinctive and Urgent Tone: Generates a clear, traditional continuous or wailing tone, ensuring immediate recognition as an urgent warning signal.
- Compact and Durable Design: Built with a robust housing, often utilizing a metal bell or durable plastic, which offers good resistance to weather, dust, and light impact. This allows for both permanent indoor and sheltered outdoor installation.
- Fixed Mounting: Designed for easy, secure, and permanent mounting using a supplied bracket.
- Vehicle and Equipment Alarm: Widely used on service vehicles, heavy machinery, forklifts, and cranes as a highly audible movement or safety warning.
- Small Shop/Warehouse Alarm: Provides an effective evacuation or emergency facility
