I’m able to find them by googling “MT4-115” and then clicking through to the product family – Eaton’s site doesn’t indicate they’re being discontinued, probably because of sprinkler alarm apps. (Besides the SH & SASH-120, one can also use outdoor SpectrAlert Advance devices with MP120K(L) supplies, as well as more exotic devices such as Flasherings.)
This listing shows a unit that’s identical to the ones I saw and features the label on the side. It seems that only later versions of the MT4 feature these labels.
That’s exactly what surprised me about the MT4s I saw: I always thought of this model as being relegated to outdoor waterflow alarm functions, so seeing multiple units inside a building is quite unexpected. This building appears to be from the early 20th century and is equipped with an old sprinkler system, which makes me wonder if the horn/strobes were added as interior waterflow alarms to create a rudimentary “fire alarm system” (I’m using quotation marks as I don’t think that such a setup would be considered a proper fire alarm system under the Ontario Building Code).
Oh, that: I was thinking of the molded-in lettering that’s on the front of NAs like the AS.
Either that or the system is literally direct-wired to normal AC power like that one system SafeTech videoed (which is backed up by neither system seemingly having a central FACP anywhere).
Indeed, in a black cabinet & with a graphic annunciator “module” too!
HS Building That I Will Not Disclose The Name Of, Yet Again
I’ve put this off WAAYYYY too long (was supposed to be posted 6-7 months prior or something…)
Restroom set-up
Heat* detector in non-renovated area
RSS in non-renovated area; note faded text
Restroom set-up, but wrecked by immature boys
The nefarious heat detector mounted above the drop-in ceiling (also in a restroom):
Gamewell-FCI single action BG-12 rebrand in auditorium
Miscellaneous Notifier equipment (black boxes) in new bungalow
Miscellaneous G-FCI equipment in auditorium
Old Edwards FA bell in locker room (scribbles on clock cover up district logo)
Last two aren’t FA related but are cool enough to show: Vintage PA speaker and some sort of 6” bell completely painted over

Wow! New E3 Installation, pretty cool! That intercom speaker is also very cool.
Weird that nobody is talking about this..
That’s actually an Apollo heat detector.

Man, that’s been there a long time &/or has faced a window for years!
Morons/jerks…
Well, it’s good to have a backup in place just in case isn’t it?
Huh, would you look at that: I do believe that’s the only single-action BG-12 I’ve seen on an actual system (the fact that it’s Gamewell-FCI is quite unusual too, since the brand that mainly seems to have made use of the single-action model is Silent Knight).
Just all out in the open like that huh? Any idea what each of those cabinets are for? (I know the one’s a NAC extender but that’s about it)
This system is all over the place isn’t it?
Considering it’s gray I’m not sure it’s in fire alarm service.
Interesting…wonder what that bell could be for.
Maybe, though “Envoy” might also be a brand name of Edwards that they use for the graphic annunciators they offer with their systems (or at least back in the day).
You can tell that’s an E3 system just from the devices? (primarily the Apollo detector?)
No real need: one brand gets replaced with another like that all the time.
Mhm: very unusual system to find such a detector on I think.
It doesn’t use the orange body and blue outline label used on general signaling bells for Edwards (it had a red outline instead), so I’m assuming it was something FA-related
I have NO clue 
probably power supply
Yeah, there’s 3 systems: one for the auditorium (probably the E3 system that FAoNY talked about), one for the non-renovated areas (Older G-FCI system, prob), and one for the new bungalow expansion (LED Notifier system).
Oh, alright I guess…
Oh, yeah, maybe.
Man…
Yeah, pretty much that’s the only VE panel that gamewell does. is it voice evac?
Oddly, pretty much every GW-FCI system I’ve ever seen has had those single action pull stations. I’ve seen some Silent Knight ones too. I don’t think Fire-Lite or Notifier rebrand the addressable versions of those.
Considering that the school has a Gamewell system, I’m thinking that, at one point, they might have had a system running Gamewell Apollo addressable devices. Considering @siren_enjoyer has never mentioned any other Apollo devices in the building, it’s probably no longer in service. I could be wrong, though. I’m also not certain whether or not the ever made any conventional versions.
My first Elementary school in Jacksonville, FL.
I went here for my little cousin’s Christmas performance tonight.
I don’t remember there being horizontal Wheelock MTs here.
These centegix strobes were not here when I was there.
This was in a bathroom.

Huh…
Yeah: last I checked Gamewell did have something of a partnership with Apollo detector-wise back in the day (not sure if they do anymore though since Gamewell-FCI sells (mostly) nothing but addressable panels now (which of course would require specific addressable detectors) & Apollo (mostly) doesn’t make the UL-approved Series 65A-series anymore (no idea know why: they were great detectors if you ask me).
Unless you’re referring to the photo quite a ways below that one, that’s not an MT: that’s an NS. Neat system though (though odd how the signals are Wheelock even though the rest of the system is Simplex).
Sadly probably because there wasn’t a need for them when you were still attending (provided that was a really long time ago of course).
Pretty sure that’s some kind of IR security or occupancy sensor & thus it’s not related to the fire or lockdown systems at all.
I was referring to the photo a few pictures under it, though the same applies to the NS as well.
Oh yeah, forgot to mention: Apollo detectors make up nearly all of the detection devices in non-renovated areas, except for a few System Sensor 2400THs in the library. And they are still active. And, if I must:
Auditorium System: Wheelock E70/90 speaker/strobes and RSS strobes, G-FCI single-ax BG-12s, Notifier FSB beam detectors (or G-FCI equivalent), Apollo smoke detectors
Non-renovated/Original-ish System: Wheelock AS horn/strobes and RSS strobes, Gamewell Century (M46) and rebranded Sigcom manual stations, Apollo heat & smoke detectors (dunno model), System Sensor 2400TH detectors (library only), Eaton beam detectors (dunno model, also library only)
Bungalow Expansion System: System Sensor outdoor Advance speaker strobes and LED L-Series strobes and speaker strobes, Notifier FSP-951 and FST-951 detectors [haven’t seen manual stations in any of the bungalows]

Yep, a gamewell E3, Only VE Panel by gamewell if I suppose..
Eckroth Plaza- Bismarck, ND
This building was opened in 2007. It houses multiple businesses over two main floors, with at least some businesses having basement areas. The main store in this building (and also its namesake) is Eckroth music, which is the main music store in my area, and the company that serves all of the music and band programs at all of my area’s schools. They also have some other businesses, such as insurance agents and restaurants.
Panel: Most likely originally a Siemens FS-250, but may have been replaced by an FC922 at some point
Notification Appliances: What appear to be Siemens U-MHU-MCS horn/strobes, and U-MCS remote strobes
This photo shows one of the horn/strobes in a Subway restaurant:
Pull Stations: Siemens MSI-10B addressable pull stations
Detectors: Siemens HFPO-11 addressable photoelectric smoke detectors
