Lmao, so unathorized access on demand by pulling the fire alarm?

Don't ask about fire power switch

Essentially yes. They should really divide data centers into zones and only unlock doors inside a zone where smoke is detected.

Because surely every smoke detector will work while the building is burning down…

most data centers are made out of concrete and isolate fires.

My point is that while the failure rate may be low the failure method is dude burns to death in a locked server room. Even classified room protocols place safety of personnel over safety of data in an emergency.

Being in a server room with FM200 fire control is the safest place to be in a fire.

just make sure the zone based door lock/unlock system isn't on AWS ;)

There's some computer lore out there about someone tripping a fire alarm by accident or some other event that triggered a gas system used to put out fires without water but isn't exactly compatible with life. The story goes some poor sys admin had to stand there with their finger on like a pause button until the fire department showed up to disarm the system. If they released the button the gas would flood the whole DC.

Halon, yes.

Most modern commercial buildings in Australia unlock doors when the fire alarm goes off.
