My church is building a new multi-purpose building.
We are just about done and now are trying to save money by doing some of the work ourselves.
The fire alarm company has tied an addressable module to the flow switch but wont do the 120 volt bell, I havent wired these type of flow switches before(only 120 volt without addressable)and not sure what to do. It seems like a code violation to wire it as I have in the past bring hot to one side of contactor(NC) and switch leg to the other, because mixing low voltage and 120 voltage in the same jbox would requirie a divider. Since this is a factory assembled UL product is this an excepion? Or do I need to get a low voltage relay and wire the coil from the fire alarm low voltage power?
