* The relay assigned to "Critical Summary" alarm (relay 1 on the IB2 by default)
will operate in the "Fail Safe Mode". "Fail Safe Mode" means Relay 1 is
de-energized during an alarm condition, opening the contacts between the
C and NO terminals, and closing the contacts between the C and NC terminals.
The remaining seven (7) relays energize during an alarm condition, closing
the contacts between the C and NO terminals, and opening the contacts between
the C and NC terminals.
Refer to the configuration drawing (C-drawing) supplied with your system for your
system's specific relay labeling.
Not all I/O points are available for customer connection (some are used for factory
system connections).
