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.

Sweep is accomplished by selecting SWP (sweep) instead of O/R (override) and them momentarily completing a circuit between the RNG (horn ring) terminal and either +12v DC or ground. Here are the relevant excerpts from the manual:
