Note: The ACU+ 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 ACU+ remaining 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.
