9838s, TrueAlerts and AS’s all in a cacophony of loud and chaotic noises.
https://www.youtube.com/watch?v=TuKjlXnPCeM - Space Age AV-32 + 2DCD in slow march time.
Simplex 9219 in continuous.
A system test in an abandoned school building. Starts with SpectrAlert Advances; later in the clip, you’ll see ADA MASS’s. The reason this is “unusual” is that the MASS’s are doing a weird, synchronized slow whoop. How this is accomplished, I don’t know, but it’s not march time as there’s no pause between whoops.
My best guess for that is seeing that the Advances are synced, the MASS’s are probably on the same circuit as the Advances and the sync protocol will send invisible pulses to keep the strobe synced but can only be picked up by Advances and the MASS’s are basically sounding on sync pulses. Notice how it’s on for a second and ceases for a millisecond and continues that same pattern. Most sync protocols use that setup when power is cut, the strobe will flash or vice versa.
Edwards 792s. You can even hear a pitch change in them at one point!
Compiled some videos I found of Rutgers dorms:
Livingston Apartments Building B. TrueAlert speakers/strobes with standard 4100U whoop/message, plus the rooms have sounder bases in continuous.
Livingston Apartments Building C. Sounder bases in continuous again, but this time with both indoor and outdoor TrueAlert horn/strobes.
Richardson Apartments, from outside. A slightly older non-voice system; you’ll hear the outdoor Wheelock MT (modern style) set to March Time outside (inside are TrueAlerts doing the same pattern), along with the sounder bases in continuous.
Quad 3, again from outside, but this has an outdoor TrueAlert doing code 3 along with the other TAs, while the sounder bases are still in continuous
Back to voice evac, but a mid-90s system with the 4100 whoop and no sounder bases. Though I never lived in this building, this is what fire drills sounded like for my first three years. Can’t really see them, but I know there are LifeAlarm speakers and 4904-9105 remote strobes in the hallways, as well as TrueAlert remote speakers in the bedroom.
Edwards 792 horn/strobes in continuous with an Integrity in code-3 in the background.
Those have got to be TrueAlertES. Since they are more high pitch, I’m gonna assume that.
Faraday 6120s that are ceiling mount along with a Wheelock AS somewhere.
I know this mall very well. They have a Simplex 4100 system set up as conventional, with 2901-9838 horns on 4903-9101 strobe plates sounding on Continuous. Some stores have TrueAlert horn/strobes (you can’t hear them in this video), while other stores don’t have alarm signals. This doesn’t count the anchor stores’ own systems.
CAUTION: Loud!
EM and 2 Advances, one set to T3 and the other continuous. The EM sadly seems to be on its last legs and seems to die out during the video, or maybe the fire got to it…
Well those were the alarms there and I can’t help it if they remove the video before other people can see it so I’m sorry. It wasn’t all that interesting but it was to me.

Here’s something unusual: 4040’s in code 3 -
Those actually sound a lot more like 4051s rather than just 4040s but it might just be me.
Simplex 2901-9838s on what I think are 2903-9101 plates as well as some TrueAlerts and some ceiling mounted Simplex 4903-9252 horns. The system is in code-3.
I think you might be right about that being a 4051.
Compared to the voices and the music (if it wasn’t edited in), the 4051s sound REALLY quiet.
It certainly is possible for a horn to actually be quieter when you would least expect it so that might be it or it could be because since it is sounding in code-3, it sounds more quiet than it actually is.
I can make out the Simplex 4903-9219 as that sound has been ingrained in my brain. I’m assuming the other horn might be a Simplex GX-90.
Simplex 2901-9838’s on 2903-9101’s, along with a faint TrueAlert in the background:
