What is your favorite SimplexTech video?

My favorite is the 2007 video “Simplex Fire Alarm Testing” because of the tapping noise the dying horns make at the beginning of the video. What about you guys?

I really like the Simplex 4005 Fire Alarm test it’s really cool it’s going on March time and some Simplex 2903 With 2901-9833

I used to watch that one! That’s the one where he says “Ready?” at the end, right?
