Are we relying on the news media accurately disseminating information from the fire alarm log?
The time stamps and other fire alarm system info come from multiple sources that include an industry rag and two news orgs. The first two feature the same forensic alarm pro. You will see that there’s inconsistency in the issue of the lobby pull switch vs. sprinkler question that I just picked by doing this updating exercise. Jeffrey Zwirn, the Miami Herald, and the NYT all have the alarm system log.

Life-Safety Lessons Learned From the Miami Condo Collapse by Jeffrey Zwirn, Feb. 2, 2022
[ul]
[li]“Prior to the catastrophe, Champlain Towers had contracted with an alarm contractor that replaced the existing building fire alarm system with a new voice evacuation fire alarm system. Among other things, it included common-area smoke detectors,
manual pull stations, voice evacuation speakers inside each of the apartments and in the common areas throughout the premises, and a
remote alarm annunciator located in proximity to the 24-hour guard station in the lobby.”[/li]
[li]“It appears that
a manual fire alarm pull station in the lobby of the building was activated before the collapse. Against the foregoing backdrop, issues surrounding liability have arisen due to myriad reports that persons who were able to get out of the building and escape before it collapsed never heard the building fire alarm system activating through its voice evacuation function.”[/li]
[li]“Preliminary forensic examination of the central station’s account history report reveals that
prior to the building collapse, the fire alarm system was in trouble, and a supervisory condition existed. The underpinnings of what part(s) of the fire alarm system was not functioning correctly and why it had not been restored to a functional mode through performing service on the system is continuing forensically.” [/li]

Lives would have been saved’: Fire alarm didn’t go off before Surfside tower collapse June 27, 2022
[ul]
[li]“The Herald exclusively obtained a “customer activity report” for Champlain Towers’ alarm system. It shows that
a fire alarm signal was recorded at 1:15 a.m. and that the building’s alarm monitoring company, Central Alarm Control, called 911 soon after. The initial triggering of the alarm system should have set off loud alarms in the entire tower, said Jeffrey Zwirn, a forensic alarm expert who reviewed the report and records about Champlain Towers’ fire system. Zwirn said that the collapse of the pool deck — which video shows ripped open pipes — would have automatically activated the alarm system when it damaged the sprinkler system. “That should then have triggered a voice-evacuation alarm in every unit,” Zwirn said, adding that the system may have been improperly programmed.”[/li]
[li]“Hallandale Beach-based Premier Fire Alarms and Integration Systems installed the system in 2017.”[/li]
[li]“Police body-camera footage from several minutes after the tower collapsed appears to show a
strobing light going off in the lobby and another in the garage. Albert Aguero said that flashing lights on fire alarms and exit signs helped him and his family navigate their way out of the building after the collapse.
But the devices never produced sounds…”[/li]
[li]In 2020, “Champlain Towers’ management emailed residents that a recent false alarm in the middle of the night was caused by “
a faulty pull station located in the lobby area.””[/li]
[li]“When the pool deck collapsed, resident Sara Nir was in the building lobby. Panicked, she told the security guard to activate a pull station.
It’s not clear if that pull station was the same one that had malfunctioned the year before. The customer activity report shows only one fire alarm signal going to the alarm company — and there’s no indication whether that signal came from the pull station or from the sprinkler system in the garage.”[/li]

One Button Could Have ‘Saved More Lives’ in Florida Condo Collapse June 23, 2022
[ul]
[li]“The building also had a
sophisticated audio warning system designed to broadcast an alert into the bedrooms of every unit. But it was never triggered, newly available deposition testimony and interviews show, because the security guard had never been trained about the system and the single button needed to activate it.“[/li]
[li]After the deck collapsed, “…the building’s alarm system was starting to activate, first at
1:15:29 a.m., when it signaled “trouble,” according to a data log.
Seventeen seconds later, a fire alarm triggered. It sent out an automated alert to a monitoring company, though it is not clear that it generated an audible alarm on any floor. Soon after, a staff member at the monitoring company notified 911 that a fire alarm had been activated at Champlain Towers.” NOTE from Maud: I calculated the time of the Fire alarm at 1:32. The time of Shamoka’s 911 calls and the Central Alarm Control call came from the 911 call log.[/li]
[/ul]
>>>>>Edit: I personally believe the lobby pull switch wasn’t working, but that Shamoka pulled it on orders from Sara Nir. I mean, if you had Sara Nir barking orders at you, you would pull the switch too. I think that the Fire alarm that got logged came from the garage after the Trouble code got logged. But I would like your thoughts on this interpretation.<<<<<
