I know this may be a stupid question but here goes.

Smoke goes in alarm starts up opens dampers, starts up stairwell fan, turns on strobes and audio.

Stairwell fan duct det goes into alarm it needs to stop the stairwell fan and close the damper while keeping everything else going. How can i make this happen?
