Alarm sounder with LED beacon IS-mC1

with signal lightintrinsically safe

Description
The IS-mC1 is a compact combined 100 dB(A) alarm sounder and L.E.D. beacon. Only one Zener barrier or galvanic isolator is required to run both sounder and beacon; alternatively the unit can be configured as sounder-only or beacon-only. Approvals include ATEX, IECEx and GOST‑R for Zone 0, and FM for Class I Division 1 / 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
