This is one cool system! This system contains of a whole system of Flush Mounted Simplex 4040s and older style Simplex Chevron’s. This system is in the works of replacement and will not be active for much longer. Got in contact with that place and may or may not be getting them. The system is being replaced by a system of TrueAlerts. As of 05/14/23 the old system is still active.

Not sure I’ve ever seen silver Simplex flushmount horn cover plates like those!
In case you were wondering, the silver thing in photo #22 is a Fire Detection Devices (or “FDD”) CF-series mechanical heat detector (which were seemingly also rebranded by Edwards, though the Edwards rebrands seem to be rare).

Brushed aluminum flush grilles… One of the most rare variants. I hope you’re able to salvage the old system.
