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 three (3)
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.
