Product Description

SNTOOM LK-SV200 Electric Motor Siren, also known as air raid alarm, is a high-decibel industrial audible warning device. It generates continuous loud alarm sound driven by high-speed rotating wind screw, widely used in fire safety warning, industrial plants, chemical engineering, construction sites, mines and municipal emergency projects, highly recognized by engineering contractors in West Africa.

The alarm adopts premium all-copper coil motor as core driving component. Sensitive trigger response and stable high-speed operation drive internal wind screw to rotate rapidly, producing sound with strong penetration. The maximum sound level reaches 121dB at 1 meter distance, effective coverage diameter up to 800-1200 meters. Clear continuous warning tone can be easily identified even in noisy industrial environments to complete emergency evacuation and risk alert.

The whole housing is integrally cast with thick aluminum alloy. It features solid structure, excellent shock resistance and drop resistance, capable of long-term stable operation under outdoor, dusty and harsh working conditions. The surface is treated with anti-oxidation process, effectively resisting corrosion and extending service life. Front mesh cover prevents foreign objects from entering the internal rotating structure and protects the wind screw.

Multiple voltage options are available: AC110V, AC220V and DC24V to match different power supply standards of factories and engineering projects. Simple fixed base design makes field installation quick and convenient. No complicated wiring or auxiliary equipment is required. Once powered on, the siren emits continuous stable alarm sound without complicated setting.

Every unit undergoes strict aging test and sound inspection before delivery, consistent performance guaranteed. Our factory supports sample testing and bulk wholesale, stable production lead time and professional technical support.

This motor siren is a reliable emergency warning solution for fire protection and industrial safety projects in Senegal and surrounding West African countries. Contact us for voltage selection and competitive wholesale quotation.
