The E2S IS-mA1 Mining Intrinsically Safe Minialarm Sounder is a compact, high-performance audible warning device engineered for hazardous mining environments where explosive gases or dust may be present.

Despite its small housing, it delivers a strong 100 dB(A) output, making it well suited to underground operations, surface mining sites and related processing areas that require dependable intrinsically safe signalling.

The sounder offers a choice of selectable tones and staged alarm functions, providing flexibility for emergency alerts, evacuation signals and process warnings.

Built with a tough, flame-retardant enclosure and stainless steel fixings, it is designed to withstand harsh mining conditions, while its intrinsic safety approvals permit installation in the most demanding hazardous areas.
