Fire Alarms in Buildings (2.0)

I just did a thread on the fire alarms at my local zoo. Fire alarms at Omaha Nebraska Henry Doorly zoo
This is at the local history museum in my city. The building used to be a train station for UP back when they did passenger service. The building’s architecture is beautiful. The fire alarm system is a Notifier system, most likely an NFS-3030, although it could be a 640. The system has a DVC, and the upper levels are voice evac. The lower levels are not. All of the notification appliances have been replaced with Spectralert advances. The NAs used to be Gentex commanders, but they removed those. There are a few FSP-851 smokes, but for the most part it is a bunch of older smokes. Idk if they are addressable, I think they are. There are also some conventional heats. At least a few are edwards recalled, but there are also a few system sensor ones as well. There is also at least 1 RSG pullstation. There is also some sort of beam detector that I am not familiar with.
