Fire Alarms in Buildings (2.0)

I don’t think fire lettering is required. The red is probably fine since it is not being used for public mode notification.

Yeah, it was inside of a bathroom.

If you wanna know where this is, its here V Google Maps

Apologies for the long post

PHX Airport Terminal 4

Appears to be a Notifier system

L-Series LED/xenon speaker strobes and remote strobes (C concourse has LED devices, D concourse has xenon devices).

Lots of spot detection and beam detection in both concourses

PHX Main Airport, SkyTrain, Rental Car Center

EST System, Genesis devices.

Marriott Tempe Buttes

Simplex system, TrueAlert horn strobes, and TrueAlarm smoke detectors on sounder bases in the rooms. Wheelock ASWP for outdoor signaling.

Marriott Residence Inn Flagstaff

Kidde addressable system. I unfortunately forgot to take pictures of the devices. This location used the older Kidde smoke detectors on the newer low-frequency sounder bases. Genesis horn strobes for general notification.

the type of smoke detectors.

Marriott Residence Inn Sedona

There was an extremely similar Kidde system here, the only difference was that the smoke detectors were the newer “OSD-style” detectors on low-frequency sounder bases.

I was in an ADA room hence the Genesis remote strobe and strobe doorbell.

Grand Canyon Visitor Center

Radionics system, Gentex GOS horn strobes, and Fire-Lite BG12-L’s. Bosch smoke detectors were all over, not pictured.

JW Marriott Camelback Inn Scottsdale

The lobby/restaurants have a Simplex system, PAINTED TrueAlert speaker strobes, and TrueAlarm smoke detectors (unpainted from what I can see). Wheelock ET70WP devices for outdoor notification. The rooms are standalone and use Kidde DETECT smoke alarms, and do not have any general notification.

Apologies for the long post again, I thought it would be easier to do this rather than make many individual posts for each system.

ESL 700-series.

That Radionics FACP sure is unique & rare!

Those can’t be up to code at all…(especially with the paint having covered the fire lettering, though they do look quite unique as a result) I’m confused about the second photo of one though since the gray color doesn’t match the wall at all.

From what I’ve heard, that was/is a Honeywell XLS-1000 (rebranded EST3) system.

I think it probably is, I was looking around in C & D concourses today waiting for my flight and there were remote paging microphones in Notifier cabinets but labeled Honeywell. Concourse C & D probably have an XLS-3000 and the “main part” of terminal 4 most likely has an XLS-1000

Definitely, I’ve never seen anything like it before.

Yeah, it was interesting and unique.

Those are up to code, because they got custom devices from simplex, for example disney fire alarm devices were custom bought.

Also, blank simplex devices also exist.

You can’t see it very clearly in this picture, but the devices were clearly painted. On some devices there was paint on the strobes, and one device had paint almost completely covering up the grille of the speaker.

Uh, no? I’m pretty sure Disney’s devices were painted by them to match whatever wall they’re on, & you’re not supposed to paint them in any case.

Yes, but “FIRE”-branded devices are otherwise supposed to be used, & in this case that’s, well, not the case since the fire lettering was painted over.

Oh? Well that’s honestly even worse than just painting over the fire lettering then (& goes to show why you’re not supposed to paint life safety devices).

honestly, i didnt know they were painted at all! I thought they were custom made from wheelock, or simplex, thanks for the fun fact!

I am very curious about that radionics system, that is something very unique. I might go digging for what it is because that is pretty cool

Edit: Well that was easy Website the image is from - Data sheet

Very interesting fire alarm system, it’s pretty big for its style. Usually these kinds of systems are small

It is quite a large cabinet, it might be due to the fact that it’s very expandable. There was a conventional BG12-L as the pull station, i’m guessing there was a monitor module somewhere since this seems to be an addressable system.

There is no code requirement for this. There are some related requirements that do exist: non-fire signals cannot read “FIRE,” and MNS signals must read “ALERT” (but they are also permitted to be unmarked if they are combo fire/MNS).

Personally , if I was planning a voice evac system for a building, I would use “ALERT” or unmarked devices, even if it’s not planned to be used as a MNS. This would be a very good future proofing step that wouldn’t cost any money, as it would allow the devices to be used for any purpose that becomes necessary in the future.

Seconded on unmarked devices in typical North American buildings – it means you can use them for CO and fuel gas alerting service with cadenced tones even if you don’t have a full EVACS or MNS at hand. That said, if you have an all-electric building with no enclosed garage space attached, no fuel-powered vehicles (ice rink maintainers, fuel-powered forklifts, etc), and no future MNS potential (for say ammonia refrigerant leakage or storm notification), you could get away with FIRE labeled devices.

Sure, there may be no requirement, but most systems use them anyway, & this system would likely be no exception if someone didn’t paint its NAs!
