Dual-port AirAlarms can not be saved as a device for the air alarm sync reasons

[mqole]

so you can use a signaler on it but not an air alarm

the list mode on the multtool and network configureator isnt working

The short answer to this is that dual-port air vents are fucked up and evil devices and you generally shouldn't be using them for the same purposes as an air vent or air scrubber. The long answer is that you are meant to link dual port air vents directly with an air alarm and configure whether they blow air in our suck air out based on the air alarm's alarm status. You use this in conjunction with an air sensor linked to the air alarm to configure what the normal, warning, and danger thresholds are.

As for distinguishing which port is for blowing and which one is sucking, I have no clue

Actually I found a video from an old PR on dual-port air vents that illustrates a sane use-case for them, but you still basically either have to do trial-and-error or just memorize which port is for pressurizing and which port is for depressurizing.
