The College of Coastal Georgia (Brunswick campus), where I currently work and go to school at, has different systems throughout the different buildings on campus. Most of the systems are Notifier systems with different SpectrAlert Advance NAs. The larger buildings have SpectrAlert Advance SPSR speaker/strobes, while the smaller buildings have SpectrAlert Advance horn/strobes. The Hargett Building and the Library have ceiling-mount Advance horn/strobes, and there are even a few L-Series alarms (both wall and ceiling mount) in the new parts of the Library. The conference center/auditorium building has Wheelock EHS-DL1 horn strobes and WST-24 strobes. There is an Advance horn/strobe in one of the restrooms there. All pull stations are Notifier NBG-12LXs with Notifier FSP-851 smoke detectors. I’m unsure of the exact model number of the voice evac panels, but they are Notifier. I haven’t seen a panel in any building with Advance horn/strobes.

The Lakeside Village student dorm building uses an EST system rather than a Notifier system. The main NAs are white EST Genesis horn/strobes with FIRE lettering and no trim plate, and Genesis remote horns in the rooms. There’s also an EST Integrity horn/strobe outside. The pulls are EST 270-SPOs with EST SIGA smoke detectors. The panel is an EST IO500, and is located in a sprinkler riser room. I got to reset it while the system was being tested. All alarms do Code 3.

The one you posted is definitely an NFS2-640.

I didn’t see a model number anywhere on the panel, so that’s why I was unsure about the model #. I have heard the system go off once, and it does a slow whoop 5 times before playing the following message: “Attention. Attention. There has been an emergency reported in the building. Proceed immediately in an orderly manner. Do not run to the nearest exit and leave the building.”

Here’s the panel from that system, located in an electrical room.

I recently started a new job in a high-rise office building that features a brand-new Simplex 4100ES system (replacing what appears to have been an EST system). The pull stations are two-stage T-bars with bilingual lettering (most of which display the new Simplex logo) mounted near Simplex firefighters’ telephones, while the smoke detectors are TrueAlarms. The signals are a mix of ceiling-mount TrueAlert speaker/strobes, ceiling-mount remote speakers, and wall-mount speaker/strobes. Judging by the red LEDs on the ceiling-mount speaker/strobes, the strobes on these signals are addressable.

Oddly enough, in certain areas, I spotted ceiling-mount Genesis remote strobes mounted near TrueAlert speaker/strobes. I suspect that these devices are remnants from the previous system that have yet to be removed.

Today, I heard this system sounding during a false alarm. I only heard the first stage signal (60 BPM chime) as the alarm had been initiated a few floors below mine. After about one minute, an automatic bilingual message was broadcast, indicating that the fire alarm had been activated on the 18th floor and asking all occupants of the 17th, 18th and 19th floors to evacuate immediately without using the elevators. The signals were silenced about five minutes later and a live all-clear announcement was made.

After staying in a high-rise hotel, those kinds of systems have always interested me. What floor were you on?

I was on the 26th floor during the alarm. I've been told that the second stage alarm automatically sounds on the floor where the alarm was initiated (along with the floors above and below) while the first stage signal is broadcast on all other floors.

I'm also quite interested in high-rise fire alarm systems! This was my first real-life experience with this type of setup.

I remember my elementary school had mechanical vibratone-style fire horns - I don't know the exact specifications - but they were LOUD. The building was two stories, with around 20 classrooms, and there were only five horns in the entire building. Even then I was fascinated with them, and counted. There were two on the first floor (one on each end of the hallway), two on the second floor (one on each end of the hallway), and one in the gym. And no matter where you were in that building, if they went off, you heard it.

Where I currently work, we have Simplex Truealert devices, with multiple annunciators along each hallway and at least one in every room (including one in my office).

Times have changed.

When you say annunciator you mean alarm? And is it a horn/strobe or remote strobe in your office (if its a single unit).

Your elementary school fire alarms. Did they have strobes or were on any sort of a strobe plate? When I think "vibratone", this is what I think of.

The elementary school on the same property as my middle school had these horns while my middle school had 4051 horns in continuous on march time "FIRE" flashers. They were replaced with I shouldn't even need to tell you what.

Here's what I found.

There was another fire alarm test today morning. These MT's are set to March Time horn.

Horn and strobe...including right there in my office (and outside my office). Lots of devices in the building, which I'm sure is a code requirement. They also have many voice capacity.

No strobes - like this, but red: https://www.youtube.com/watch?v=GuQ74Kf70cI

This was back in the 1980s, before strobes were used in most buildings (at least where I lived).

Ah so it was a Simplex 4040 horn or something like that. OK. I see it. Just wondering. :)

That's cool, I learned a ton about these systems in my fire alarm course, but have yet to see one in action. I have worked on high-rise systems, but they were installed before this requirement. The one building in my city is a 28 floor condo building, which has a Mircom FX-2000, but it is a single stage system.

Another false alarm occurred this week and I was able to get an audio recording of the event. The recording includes the first stage signal and message along with two different all-clear messages (and some commentary from my coworkers, unfortunately). I wasn't quick enough to get a full recording of the second all-clear message, which indicated that the building systems had been reset; only the French portion of this message is featured in the video.



Hopefully the video will work properly!
