IS-mC1 IS-minialert
 
The IS-mC1 is a compact combined 100dB(A) 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. 
 

Features:

• Input overload and reverse current protection
• End of line resistor certified
• Auto synchronised sound output
• Prismatic lens optimises L.E.D effectiveness
• Available with custom tone configurations and frequencies
