The E2S IS-mA1 is a compact yet high-performance intrinsically safe alarm sounder developed for hazardous area signalling. Producing up to 100 dB(A), it ensures clear and dependable audible warnings in environments where reliable alarm indication is essential.

Certified for Zone 0 use with ATEX, IECEx and GOST-R approvals, and FM approved for Class I Division 1 and Class I Zone 0 applications, the IS-mA1 is suitable for a broad range of intrinsically safe systems, including fire, security and process control installations.

The unit incorporates protection against input overload and reverse current to help protect connected equipment. A certified end-of-line resistor supports effective system monitoring and fault detection.

Automatic sounder synchronisation ensures consistent operation across multiple units, while custom tone and frequency options allow configuration to meet specific site requirements.

Its compact, wall-mounted design makes it an excellent choice where installation space is limited but high output and performance are required.
