All times in UTC:

 The attached plot shows that the fier alarm activated at approximately 2 minutes after 00:00UTC.  Lockloss occurred approx 3 minutes after the alarm had been silenced.

It seems that the PSL Mic detected the alarm at roughly 00:02:23 until 00:09:12. The duration of it was approx 7 minutes.

I picked a common, control room StripTool channel, H1:LSC-TR_X_NORM_INMON,  to represent the time of lockloss which seemed to have occurred at approx 00:12:16. Most all of the other mics show a spike feature at the same time as the TR_X plot indicating some correlation.
