After a message popped up on the ISC_LOCK guardian to review the last check of the AS port fast shutter, and we realize the last check should have been during the power glitch recovery, we manually checked the functionality of the fast shutter. The fast shutter appears functional, stopping light into the OMC breadboard and the GS13s show an impulse.

The manual check: 
Setup:
- The IMC is locked, and the IFO aligned enough to see flashes on the AS port camera
- Watching the OMC Breadboard QPDs MEDM screen to see a spot moving around (channels H1:ASC-OMC_A_[YAW,PIT]_OUTMON)
- Watching the HAM6 GS13s on a dataviewer session to watch for fast physical motion of the shutter (channels H1:ISI-HAM6_BLND_[X,Y,Z]_GS13_CUR_IN1_DQ)

The test:
- Use the fast shutter detail MEDM screen (sitemap > LSC > shutters > bottom middle "Detail" under the "HAM6 Fast Shutter" name)
- Hit "open" then "close" several times, watch for light to disappear from the OMC Breadboad QPDs, and watch for large impulse on GS13s.

We need to do a similar test after every power outage, no matter how small.
TJ has agreed to create a guardian "PRECHECK" state such that we can do manual check of the fast shutter functionality. (To date we've only done the automatic checks every 48 hours).
Note: There already exists a guardian check in the FAST_SHUTTER node, however, the check is programmed to fail without the IFO MUCH further into the lock acquisition sequence (i.e. DRMI locked), and we'd prefer to check the functionality far before this.
