An optional Relay Interface Module (RIM) uses relay contact closures to indicate
the operating status and alarm condition of the Parallel Capacity/Redundant
system . A maximum of two monitoring accessories (RMPs, RIMs, or SCMs) can
be installed. See Table 11---1 for the number of accessories permitted. Figure
11---2 shows the RIM with its four 15-pin connectors labeled J1 through J4.
