Description  
The Safety Barrier ES58-2 for the galvanic isolation of  
the detectors in the hazardous area serves for the de-  
sign of an intrinsically safe electric circuit. The plastic  
surface-mount housing allows to mount the safety bar-  
rier near the hazardous area.  
number of detectors depends on the country-specific  
regulations and can be found in the Connection of De-  
tectors.  
Due to the galvanic isolation, the earth leakage moni-  
toring can remain activated in the fire detection control  
panel. Thus, the installation can also be monitored in  
the hazardous area.  
The built-in zener barrier limits the current and the vol-  
tage of the detector line, as well as the electric energy  
stored in the intrinsically safe circuit. The maximum
