Fire Alarms in Buildings (2.0)

I find this curious – it seems that there’s a misunderstanding out there for some strange reason that conventional panels can’t be used for elevator recall? (I haven’t been able to find anything that’d prohibit conventional panels and 4-wire relay detectors for recall service, at least for the common case of N/C elevator recall circuits.)

You are right, but they likely decided to go with an addressable panel as they could probably just reuse the existing wiring in the building or add minimal wiring, making it cheaper.

I think the bigger question is “is it sprinklered?” I reckon that sprinklers, especially in a managed environs like a hotel, would cover for what would otherwise be a lot of sins…

Yes it is a sprinklered building, but many of the sprinkler heads look to be heavily damaged. I would argue that a fire alarm system is just as important as a sprinkler system; especially in a building as big as this where the fire alarm system may be used for other emergencies.
