To connect a device that should be powered off during a boiler lockout condition, follow the same
instructions as above and use the ALARM NC terminal rather than the ALARM NO terminal.
NOTE: In a cascade system, the alarm output of the boiler addressed as #1 will also be active if the
master boiler has a lockout condition. The alarm output of boilers addressed #2-7 will only sound if a
lockout condition occurs on that specific boiler.
