Hm. Is it a network system? I know that in my area we have a large hospital that has been built on to a bunch, and I think it has a Siemens networked system. I remember seeing at least one MXL node. Although I don’t think the older areas of the building are voice evac.
It may be a networked system. However, that doesn’t change the fact that none of it is voice evac and it is a very old and outdated system.
Hm. I don’t think it’s required tho. Another hospital in my area only has UMNT horn strobes, and some ZNS horn strobes as well. Although the hospital isn’t that big. Although the hospital does have a paging system.
It may be grandfathered in, but that still doesn’t mean it’s the best choice for safety.
Actually that’s just a different design that doesn’t have a bulb that sticks out - I’ve seen that design before.
The building isn’t that old tho, and I think it was renovated recently as well.
I’m meaning the building that I posted about.

How do these sprinkelers work?
No, those sprinklers are just fine. This is a special type of sprinkler called the “XL Commercial Flush” series that Reliable manufactures. The pic below is their horizontal sidewall model, but they also make a pendent model, which you took a photo of.
They’re meant to be lower-profile than your usual pendent sprinkler, and they sort of do the same thing as a recessed or a concealed pendent.

System is a Fire Lite addressable system, most likely an MS-9200UDLS. NAs are system sensor Advance HSs for the most part, but there are a few L series devices as well. There is also an edwards adaptahorn as well. Also, in one of these pics there is an advance wall mount on the ceiling, remember that those can be technically mounted on either wall or ceiling.
I thought the system sensor advance strobe was rated for wall mount
So I may or may not have talked about this system before, but this is at the event center in my city. The system is an EST3 voice evac. The NAs are Integrity SPSTs. The detectors are 1st gen SIGA.
On some of the devices, you can see that the fire lettering has completely faded.
From what I remember, it is rated for both.
Iirc, both are technically rated for both. Ideally, you mount the wall mount one on the wall, and the ceiling mount one on the ceiling for correct fire lettering orientation
I don’ know what the first two are but the others are a Gentex commander (can’t tell which one it is), a Wheelock AS, and a National Time and Signal fire alarm (possibly a 512 according to someone on these forums). There are also Gentex Gx90s and SHG-24’s as well as Wheelock exceders in the newer parts of the building. This is all at my travel school.
Nice vintage fire alarm devices
The first alarm is a Wheelock MT4-24-LSM, while the second appears to be a Simplex 4000-series mechanical horn (most likely a 4051 or 4050 as the 4040 has a a circular disk in the middle of the diaphragm (which that horn lacks) & the 4041’s diaphragm is silver (though going by the rest of the signals it’s probably a 24VDC 4051). As for the Commander, given the lack of a hole for the candela setting, it’s likely a Commander 2, which is the same as a Commander 3 but fixed-candela (though I think newer Commander 2s have candela windows).
If you look closely, the trim plate was put on upside down. The candela window could be on the other side. Also it’s a bit of a mounting fail being on the ceiling.
