Unitrol Touchmaster Delta not sweeping

Hello. I’m new to all of this and looking for some help. My dad purchased a unitrol Touchmaster Delta to go into my patrol truck. I had it installed (the local guy my agency has wire our vehicles). I cannot get it to sweep through the tones when in test mode. I was wondering if anyone had any ideas and could help. I’m hoping he just didn’t wire it up properly and it can be fixed easily. It means a lot to have something in my work truck from my dad and would love to have this siren fully functioning.

Thank you very much for the help in advance.
