Description
Specifi cations
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.
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
number of detectors depends on the country-specifi c
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 fi re detection control
panel. Thus, the installation can also be monitored in
the hazardous area.
