SMOKE_EXTRACT_CTRL
Point smoke extraction: opens the incident zone's damper bank as a bit mask, ramps the exhaust fan to the commanded rate and proves the flow.
When to use it
Use SMOKE_EXTRACT_CTRL when a tunnel has a transverse or semi-transverse extraction duct with remotely operated damper banks per zone, and a commanded incident zone must be extracted from while every other zone stays shut.
