Fire Alarm Activation #12

Just a short video of a fire alarms sounding off in an apartment complex. The system was silenced a few minutes after filming, which leads me to believe this was a drill, test, or a false alarm. This facility was formally a school, and it appears some older signals were kept alongside newer devices. No clue what panel this is, but I suspect it's a newer Notifier system that outputs filtered DC.
Components:
System Sensor SpectrAlert Advanced Horn/Strobes
Federal Signal 450D + VALS Horn/Strobe
Notifier BNG-1R (?)
Signal coding is continuous, with System Sensor sync for newer signals.

Love those old mechanical horns!

That is the lowest pitched B4 vibratone I’ve ever heard. I thought it was a C series when I first heard it but the tone is similar to that of a B4.
