E2S IS-mC1-R/C — intrinsically safe combined alarm sounder and LED beacon, red housing, clear white LED.
In the E2S part code the R is the fixed red enclosure and the letter after the slash picks the LED colour, so R/C is the white LED build, not a second body colour. Sounder and beacon can share one Zener barrier or galvanic isolator, or run from separate barriers for independent control. It is certified intrinsically safe apparatus, installed to control drawing D 5037 and the NEC.
