With 2216 cabinet,the external alarm could be configured and simulated by the help of a short cable which I call it “signal transformer”. Unlike the 2206 where by the RBS has a direct connection from the OVP panel to the RBS through a single cable.With 2216 cabinet, one has to get this short cable so as to serve as an interface to the OVP panel so that the external alarm signal from the OVP could be transformed to what the RBS can understand and interpret it clearly on the OMT for you the engineer to understand. Till you get that signal transform cable, it’s not going to work.
Thanx.
