Ok this mall in San Francisco is interesting.
One part of it has a honeywell system (Could be active, i dont see any other alarms in that part of the building, unsure if panel based or two wire)
Honeywell “Local Alarm” pull station
Honeywell Branded 4037?
and the other part has fairly modern equipment (EST Genesis, Smoke Detectors, etc.)
The Genesis here could be a possible retrofit
This other Genesis has an ADT (smoke detector?) near it. Ive seen things like those quite often in Malls
Incredibly unlikely that the honeywell system in the other part of the mall is somehow interconnected to the part with newer alarms.
The parking garage has 2 Gentex detectors and a direct view LED exit sign.
