There will be a (hopefully) low-voltage pair of wires coming from the central vac to the outlet. The outlets work in the same fashion as a light switch in concept, except the pair of wires is (hopefully) only completing a "hose is inserted" detection circuit, and not providing power to the vacuum. I'm almost certain they wouldn't do such a thing.
Unplug the vacuum, then remove the plate and inspect the wiring and the metal contacts that come into contact with the meal hose end. Hopefully the issue is right there. It may be back at the vacuum, or it may be at a splice from one of the other outlets or somewhere in between. Not fun.
