21:49 - Received a text message on the CCoC cell phone stating that there was a 911 call from Building 85 and that first responders were en route.

22:01 - While en route, I received another text message stating that there was no smoke and no fire, the alarm was cleared, and the first responders had left the site.

~22:10 - I arrived on-site and spoke to the guards. Two Fire Safety systems personnel had been on-site and investigated, and the all-clear had been given. It was reported that the alarm came from Room 118, the same sensor that had given a false alarm on 10/17.
