Hey there I am having a issue with a 3 bell system it is set for a small business to let anyone know if someone enters the business. One is just a single chime the other one that works properly is a bell which has contacts and hammers the bell it works properly also the third is a fire alarm type bell they all go off but the third bell sticks and won't shut off. As far as I can tell it is split from the contact bell wiring. I am wondering how power would still be getting to one bell and not the other
