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.
Louis D Brandeis High School in Helotes, TX Siemens system.
Panel: unknown
Annunciator: unknown
NAs: Siemens rebranded Wheelock Eluxas
Pulls: Siemens XMS-D with Stopper covers
Smokes: unknown
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
This city uses the 2021 IFC, and 1103.7.1 requires voice evac in existing Group E occupancies (with occupant loads above 100) unless they have an existing, previously approved fire alarm system. When a system is replaced, the building no longer has an existing, previously approved system, which means the new system must provide voice evac, so this is likely a code violation.
That’s also the exact code that my city uses. I haven’t seen a new system in a school with horn strobes in over 8 years.
Today is an actual performance but the disable/test led is not illuminated, so the stage detector is still not disabled ![]()
Apparently only the dialer is bypassed
Oh boy. Hopefully there is not false alarm. That would be very unfortunate in the middle of a performance.
Yeah, as well as dangerous given the concept of “alarm fatigue”: why they didn’t just disable that zone/point instead I’ll never know, as that would be the optimal solution to such a problem.
Good thing it did not happen, but I asked the custodians, and they said it is disabled (with fire watch in my school) but there is no disable/bypass leds on
Could it be physically disabled (covered)?
I don’t see any cover on the detector
San Antonio Eye Center in San Antonio, TX. System is an Gamewell-Fire Control Instruments addressable system.
Panel: Gamewell-FCI 7100 (assumed by annunciator, no picture)
Annunciator: LCD-7100
Pulls: MS-7AF
NAs: System Sensor SpectrAlert Advance
Smokes: none (fully sprinklered)
I just found some photos of another new building that is being constructed in my state (not at all related to this one), and that building is still actually getting some SL- series (rebranded Wheelock LED3) devices. My local Siemens dealer appears to have a lot of old stock, so I’m not ruling Siemens out yet.
