Botsford Elementary School (Livonia) - opened in 1953
Annunciators/panel:
Original system: Unknown, presumably a National Time & Signal Corporation (Natsco) 2000 series or earlier
Current system: Older GE/EST addressable model (circa mid-to-late 2000s?)
Detectors:
None noticed
Pull stations:
Original system: Unknown–wall plates in the original building where the old devices were are more square shaped than they are rectangular, though the old devices could have had mounting plates. If I had to guess, they were most likely Natsco Type 3500N break-glass stations. At some point, the school had a classroom wing addition, and wall scars from the old devices suggest there were Natsco Type 620M models.
Current system: GE/EST SIGA-278 models
Notification appliances:
Original system: Based on wall scars, they were Natsco Type 310, 311, or 331 horns. The classroom wing addition used Natsco Type 411F horns, and while the flush plates still exist, the horns themselves are long gone. Unlike other places I’ve visited, I did not notice any Natsco trouble bells.
Current system: GE/EST red ceiling-mount Genesis horn/strobes and strobes; there are at least three red wall-mount horn/strobes with the ‘FIRE’ lettering scattered about, however.
Other notes:
The school has a working Natsco bell system that is almost all original! It consists of P806 (black gongs), P806F (classroom wing addition only), and P810FG models, plus one red P804 in the gymnasium, but whether it was used for the original alarm system or is tied into the current bell system is unknown. All bells, to my knowledge, have the -LAKE- labeling on their tags, and are controlled by a Natsco master clock panel from the 1990s.
Very peculiarly, there are two hallways that meet with the main hallway in t-intersections that have two unknown bells at their corners! One has a 6" gong that was painted over with white paint and a flat square mounting plate. The other one is nearly identical, except that the gong is missing, but the gong’s mounting mechanism is still there. Both are mounted next to what I believe are recessed vintage emergency lighting, and both are very close to P806 bells nearby, so I have no idea what these could have been used for, if they’re even still used at all.
