Setting off rare Simplex 4050-80s

Fire Alarm Test #103 This building is one of the oldest in the district. In the original parts it has simplex 4050-80 light plates with 4051 horns. However unfortunately the 4050-80s were all burned out. I plan on trying to fix them next summer. There was an addition to the building at one point that has a 4903-9219 in the hallway and simplex rebranded GX-90 mini horn strobes. The portibles were also later added and the panel was downgraded to a gamewell E3. all original devices remained at least.
