Adjusting air alarm settings.
"Scrubbing" is the default mode
"Panic" empties the room
"Fill" turns off the scrubbers and activates the vents in an effort to replace lost air
"Cycle" will trigger first a panic siphon then a fill mode in order to empty a room of contaminants before refilling it from the supply pipes
"Replacement" will turn on the panic siphon while continuing to add air into the room
"Off" will disable all attached devices. (This is useful for breached areas)
