Oh, okay.
Ah okay: that answers that then, heh.
One of the several bell strobes in my school (439D-10AWC vibrating bell on an EST Integrity strobe plate).

Fire alarm huh? What happened exactly, do you know?
False alarm caused by fog machine during rehearsal for school play

lol. I’ve see fire alarms caused by fog machines before, but you’d think a space that’s designed for performances would be designed with a fog machine in mind. Another option would be fast-dissipating, or low-lying fog, so that it can’t reach the smoke detectors. I know they use fast-dissipating fog in my school’s gym, so that the fog doesn’t stay around for too long, and so that it is gone before it can reach the smoke detectors.

I work on the tech crew for my high school theater. During runs with haze, we make sure to keep all of the doors closed as well the ones into the hallway. The unfortunate part is that there is a smoke detector right in the shop connected to the stage. We have to make sure to keep that door closed, or it will set off the fire alarm, which has happened before.

I saw this in a photo online:
It’s very difficult to tell, but it looks like an Eaton Eluxa speaker/strobe to me. Although I’ve said before that this system is probably going to just get a 4100ES upgrade, I’ve since found out that this school district also uses many Honeywell systems in new buildings. It could be an addition/upgrade to the existing Simplex system, a change to Autocall, or to a Honeywell brand. Only time will tell.

Every door out of the auditorium in my school also has at least one smoke detector outside of it (Siemens OP921). I guess if they had issues, they could call the Siemens dealer in my area to switch them out for Siemens OOH941 multi-criteria smoke/heat detectors that use a combination of a photoelectric smoke sensor, heat sensor, and CO sensor to determine whether or not there is a real fire (similar to the old FP-11 and HFP-11 devices, but these are still modern, UL listed devices that aren’t too ignorant of real fires). I’m sure other brands have similar products. I know for sure Edwards does. Siemens and Edwards have been having a “who can build the most false alarm-resistant detector” battle for decades at this point.
I think this is a custom annunciator for the cheesecake factory near me, i do know this is some sort of notifier system.

I think that’s actually a Marlin Controls lighting control system. Still, it’s certainly interesting that it has custom Cheesecake Factory styling.
The EST equivalent of a new multi-criteria detector would be the SIGA-OSCD. I’m not exactly sure which models are installed in my school, but I know there are SIGA Optica detectors and the Landis + Gyr equivalent of older SIGA-HRS heat detectors.

I was here today to watch a hockey game. It was pretty intense, as it was the home team vs. their biggest rivals.
Anyways, I took some photos. I also found some interesting information. Here’s the photos:
These photos show some devices on the system:
These photos show some of the blank plates, where 2903 horn/lights used to be. In these places, many ceiling mounted devices were installed for better coverage. Most areas saw the 2903s being directly replaced, as can be seen above, though. Here’s the blank plates:
Unlike the red plates where the new speaker/strobes are mounted, these ones were painted to match the walls.
The photo below shows the panel itself. I never knew where the panel was located before now. Through the window of a dark office that I’ve passed by many times before, I noticed a green LCD glowing on the wall. I thought it looked suspiciously like a 4100ES LCD, so I put my phone up to the window, and took the following photo:
Needless to say, I was quite surprised. I never knew it was right there in plain sight. I wish I would’ve known this when the old panel (quite possibly a 2001) was there. This Autocall system does seem to be installed quite professionally, especially for a retrofit job. I find that my local Autocall dealer tends to do some good work. That makes sense, as they are a locally owned security company that has high ratings. You can see their brand sticker below the screen inside the panel. If you’re wondering about the equipment on the left, it’s mostly lighting control stuff.
Due to the very cool (and well done) retrofit job, and the Autocall system, this is one of my favorite systems in my area. It’s pretty cool to see a Simplex system converted to Autocall. That’s been happening more and more in my area. The only other system I might’ve liked more was the one at my district’s old high school, but that has now been reduced to rubble.
Here’s a photo of a 2001-SRN behind some trees outside:
Raddison Hotel- Bismarck, ND:
I saw this in photo online. This is a hotel/conference center in my area. I’ve suspected they had these devices for a while, but this is the first “moderately clear” photo I’ve seen. I’m fairly certain this was a 2001-8001 voice system at one point, and I have no evidence to suggest that it’s been updated at any point. I really hope to get closer to it at some point.

This was a large indoor storage warehouse with a Simplex or Autocall system. It was demolished by the owners, and they are now building a two story self storage facility in its place. The banner and dumpster at the top of the hill on the left side of the photo show the logo of my local Autocall dealer, so I’m guessing that’s what will go in there. I’ve seen quite a lot of new Autocall systems lately in my area.

I was here again today for my second time. Before I even walked in the door, I saw a yellow light on the annunciator. When I looked, there was a missing device trouble on a detector. There didn’t appear to be any maintenance happening on the system. This is a good show of modern Honeywell quality lol. A system that isn’t even a year old is already having issues. It’s a good thing I haven’t seen a new Honeywell system in my area since this one.

That’s a nice system! It looks like it could be brand new! I’m very surprised that it’s not a voice system, though. What did that system replace?
I don’t know. Today was my first time going there. I’ve never been there before
