Safety Barrier Y72221
The Safety Barrier Y72221 (fi g. B) is used for intrinsi- cally safe electric circuits. The
detectors in hazardous areas. Due to the galvanic isola- tion, the earth leakage monitoring can remain activated in the fi re detection control panel.

Protocol Interface IST200
The Protocol Interface IST200 (fi g. C) serves for the design of an intrinsically safe electric circuit in ADM loop technology. It allows the bidirectional data traffi c between fi re detection control panel and fi re detectors in hazardous areas via an ADM loop with System Sen-
sor/200 protocol. The interface is always used toge- ther with the Safety Barrier Y72221. The Surface Moun- ting Box SMB500 is required for mounting the protocol interface.
