After 14+ years of working at home, I needed to take a day to go back out in the field as a “refresher.” Today I am testing a 4100ES that replaced a 2001.  The main floor underwent a remodel so those AV’s are 4906–9127 with 2099–9756 pull stations.

The upper floors have the original devices still intact. I chose a 4251-30 pull station which activates the 2901–9806 mechanical horns with the 2903–9001 light/trim plates.
At the very end of the video, there is the old 2001 cabinet (square blank box with black trim) on the wall which is used as a junction box for the old devices. Beside that to the right is the old fire pump controller.

I hope you enjoy this video as much as I did making it. Thanks to all of my followers.
