False Alarm on ISS
24 September 2004: NASA Space Station On-Orbit Status 24 September 2004
“Shortly after C&C3 took over as Prime MDM, fire and smoke alarms were set off from the FGB, annunciated (and reacted to) both in the Russian and U.S. segments. The crew reported no smoke or smell in the cabin and felt comfortable enough to return to bed. It is unclear at this time how the FGB alarm was triggered and whether it was related to the C&C MDM transitions. Currently under investigation.”
