NOTE!
The controller relay assigned to “Major 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 seven (7) remaining 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.
NOTE!
The relays may be preprogrammed for specific functions. Refer to the configuration drawing
(C-drawing) supplied with your system for your system’s specific configuration.
