This is the speaker that is near my alarm panel.
The original owner disconnected the ground side of the speaker. I have tested the speaker and it works, however I can't get the speaker to go off when my alarm goes off. I have a bigger home, and I cannot hear if my alarm is going off from my Bedroom.
I have attached a lot of images of how its set up. Hoping someone more experienced in alarm systems will be able to point me in the right direction. It doesn't seem its just as easy as hooking up the ground.
The original owner put the power wire on the main panel on panel number "3", you can see the ground wire hanging off. I have attached a few pieces I found inside the panel that's not installed.
