Fire Alarms in Buildings (2.0)

Hilton Minneapolis-St. Paul Airport- Bloomington, MN
Panel: Simplex 4100+ with voice evac handling most of the system, and a Fire-Lite ES-200X handling addressable devices for elevator recall. The ES-200x most likely is wired to trip the 4100+, but I doubt that it works the other way because there are no notification appliances or anything on the ES-200x.

Notification Appliances: Wheelock E(T)70-w speakers. There are no strobes present in the entire 10 story building.

Pull Stations: Mostly ESL 103-01 pull stations with some Fire-Lite BG-12Ls as replacements

Smoke Detectors: Mostly System Sensor 2W-Bs, a few conventional Simplex TrueAlarm smoke detectors, and Fire-Lite SD365 addressable smoke detectors in the elevator lobbies tied into the ES-200X

Overall, I would say this building could do with a complete fire alarm overhaul. It feels like the owners have been trying to get by with the cheapest way possible of keeping their system compliant with the grandfathered codes that apply to their building.
