Disclaimer: This is technically 2 schools part of the same district where I was called to assist in conducting drills consecutive of each other. In the first clip, at the elementary, which had the 4051’s in march time; the system was an old 2001-8032 that was later upgraded to a 4010 classic. For the second half, at the high school, we have a 4100ES upgraded from a 4002 that of which was expanded to cover multiple additional zones.
