Would be nice to have some Guidance for high pressure VTP alarms

(FIG.1,2)
AA[08,14,16,17] vacuum alarm came in,

(FIG. 3,4,5)
Before I could plot & pull up the vacuum spikes, the alarms & levels resolved themselves.
Seems to be a common spike which happens ever so often. Quickly drops back down soon after to nominal levels (last image)

Regardless I'll keep an eye on it throughout the night.

Anyone know what/why this occurs?

LCW south access & East Arc alarm came in,

(FIG. 3,4,5,6,7,8)
Before I could plot & pull up the LCW commander, the alarms & levels resolved themselves.
Seems to be a common spike which happens per week or so. Quickly drops back down soon after to nominal levels

Regardless I'll keep an eye on it throughout the night.

Anyone know what/why this occurs?
