Hello just showing off my apartment buildings control panel. These are only a few years old they were put in 2020. Just right before I moved in the alarms have only gone off 2 unexpected times during my 4 years here at the complex. They sure are loud when you have 6 Simplex 4903s they bounce off the walls and I’m not exaggerating how loud they are lol. Anyways I just thought I share the simplex panels we have in our building. I did happen to notice when we were in our storm shelter area they did have one covered in a glass box would that be the main panel or would this one in the hallway be a main panel there’s only 2 panels in each building. And for the next test I asked if I could set the alarms off in my building he said yes so that’s an added bonus 
. Looking forward to that next month gonna be brave as I have sensory to sound issues for loud noises but have an intet in alarms :
