The controller relay assigned to “Critical Summary” alarm (relay 1
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 controller’s 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.
Not all I/O points may be available for customer connection (some
may be used for factory system connections). Refer to the
configuration drawing (C-drawing) supplied with your system for
your system’s specific configuration.
