I’m surprised that’s even allowed under code: wouldn’t it make sense to have FPL always be red so that it can be readily & precisely identifiable as FPL?
forgot to say that’s wire for something else..
Oh, it is? It looks like it’s hooked straight to the NA though.
Yeah, it goes over it, there’s a hidden conduit somewhere connected to a backbox.
What do you think about this?
I recently attended a Christmas market at an old industrial building. This building has a rather peculiar system: the pull stations are 270-SPOs, and the signals are pre-ADA Wheelock MT4 horn/strobes (identical to this unit). I also saw an AC-powered Kidde smoke alarm with an LED strobe. I did not see a panel or an annunciator.
I noticed that the MT4 horn/strobes have labels reading “fire alarm device - do not paint” on the side, like other recent Wheelock devices. This leads me to believe that they are newer models (more specifically, MT4-115-WH-VFRs). The horn/strobes are in fantastic condition and, based on the appearance of the backboxes and conduit, seem to be recent additions. If that’s indeed the case, I never thought I’d come across a new installation that uses pre-ADA horn/strobes; this must be the most anachronistic use of a device I’ve ever seen.
Reminds me a lot of the unusual 120VAC-powered no-FACP system that SafeTech came across in this video.
On the side? Last I checked they often have such a warning on the front, but I don’t think I’ve ever seen a Wheelock NA that had that on the side!
That is indeed quite odd: heck Wheelock probably doesn’t even make that particular model anymore given the complete discontinuation of the MT-series as a whole do they? (surprised they made it up until now though considering it probably wouldn’t see much use outside of say waterflow applications given its frosted (& thus non-ADA) strobe & 120VAC power requirement)
I think you’re right that they are now discontinued. After looking at both the Wheelock-Products and Eaton websites, I can find no mention of these devices being for sale anymore. Now, it seems like the Potter SH-120 and SASH-120 are the only options for 120v sprinkler alarms. It’s no wonder I’ve been seeing them on every new building in my area. The most recent MT4-115-WH-VFR install I’ve seen was on a building that was opened in 2023.
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).
