NOTE About "APC Beeping Box" logged above: This is a known issue. It is a "low battery alarm" for the Uninterruptible Power Supply (UPS) for something related to the PSL in the PSL rack.
Wanted to note this in case a mysterious noise is observed during future Observing Runs (a similar example would be phones in the PSL/LVEA which were being rung).
