Interesting not because of the system (Simplex 4903's that aren't even visible), but because of what happened. A light fixture caught fire, and one of the kids goes to pull the fire alarm. It takes quite a while for the system to activate.

Either the system has a long alarm verification period, or the kid thought he pulled the alarm when he simply opened the Stopper cover.

9838s, TrueAlerts and AS's all in a cacophony of loud and chaotic noises.

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!
