Here’s a Hochiki system at a local EZPawn
Huh I never knew they made panels and pull stations
I think they rebranded the pull station and smoke detector. The smoke detector looks like a SD505-APS
No silent night rebranded hoticki
Oh really? Didn’t know that
The panel is Kentec-designed, as the Hochiki Corporation has owned Kentec Electronics for some time now, & the pull station is a rebranded RSG RMS-1T-KL-LP, but the smoke detector I’m pretty sure is one made by Hochiki themselves, as Hochiki has made detectors for other companies (Simplex most prominently).
Hothiki manufactured smoke detectors for silent night and Simplex
Well, TIL. Didn’t know that
This is a sad sight. This is my district’s old high school. As you can see, it’s clearly being demolished. This Auditorium was the second-to last part of the building to be built, and it was also the second-to last part of the building to be demolished. They started at the opposite end of the building. If you look to the left of the door on the left side of the photo, you can see three devices on the wall. That’s a Pyrotronics rebranded Wheelock 7002T, a 120v Wheelock sprinkler bell, and what is likely a 24vAC Simplex class-change bell. Here is a better view from the 2021 Google Street View:
The Wheelock bell looks much newer than the other two devices, and it looks almost brand new on the 2011 Street View, so it was likely replaced around 15-20 years ago. The Simplex(?) bell was installed in 1986 when this addition was built, and the existing Standard Electric Time master clock was replaced with a Simplex model. This was the only bell in this addition, as the indoor S.E.T. bells from the original areas could be heard throughout the addition, and it was supplemented by a tone over the intercom system (that had admittedly very limited speaker coverage). The 7002T rebrand was tied into the Pyrotronics XL3 addressable system that was installed in 1986 as part of the addition project to replace the school’s aging Standard Electric Time AC coded system, and it acted as an outdoor notification appliance. There was another rebranded 7002T on the other side of the wall that acted as one of two notification appliances in the auditorium, and there was one straight across from it on the opposite wall of the auditorium that acted as the other NA in the auditorium.
It’s still crazy that this building doesn’t exist anymore. It’s now essentially all gone. I had a hard time writing this post, as I kept accidentally writing everything in present tense.
Incidents like that really drive home why it’s so important for us collectors & enthusiasts to make sure all of a building’s life safety devices are removed/salvaged/saved before it’s demolished (or “do our part” one could say).
Did you try to save those?
I went to the Spaghetti Warehouse in Dayton Ohio and here is what I found!
This was my first time seeing a BG-6 in public!
I also noticed the Trouble Light on that mysterious Annunciator was flashing.
I think this system is probably from the 70s! i’ve also never seen an annunciator that looks like that. or really any of those devices in person.
Unfortunately, I was not able to save them. This is something that I’m really not happy about.
Well, the King Of Prussia netflix house has finally given an answer of what system it has, SIEMENS! Im pretty sure the dallas location might have siemens devices too.
Looks like we have a florida native! hah im kidding, i also have a question, what devices are super common in FL?
There’s one of those newer Eluxa devices with the smaller “FIRE” lettering. That’s the first Siemens one I’ve seen. Most of the SL2- series in general isn’t all that common, as they weren’t sold for very long before the ACEND devices came out. I’m thinking that they were just a placeholder, because Eaton probably discontinued the SL- series before the ACEND devices were ready to be released.
Yeah, the mixing of the Siemens signals though generations is quite common, as Siemens went through four device generations in under 5 years. I know of some places that have at least three of those generations. For example, my school that opened in late 2024 has primarily SL- devices, but it also has some SL2- and SC- devices. I know of some places that have Z- series devices in the mix as well.
There was a bomb threat here yesterday. Because this is a mass notification system with “ALERT” labeled devices, this system was likely put into action.
