E2S IS-M A/C 1 Series Intrinsically Safe Alarm Sounder Beacon

 

E2S IS-M A/C 1 Series Intrinsically Safe Alarm Sounder Beacon for Hazardous Area Signalling Applications

The IS-mA1 is a compact, 100dB(A) Intrinsically Safe Alarm Sounder. Approvals include ATEX, IECEx and GOST-R for Zone 0 applications and FM approval for Class I Division 1 and Class I Zone 0 applications. The IS-mA1 is suitable for all intrinsically safe signalling applications including fire, security and process control. The IS-mA1M version is also available for Group I mining environments.

The IS-mC1 is a compact combined 100dB(A) Intrinsically Safe Alarm Sounder and L.E.D. beacon – only one Zener barrier or galvanic isolator required to run both sounder & beacon or alternatively the unit can be operated as individual signals. Approvals include ATEX, IECEx and GOST-R for Zone 0 applications and FM approval for Class I Division 1 and Class I Zone 0 applications.
