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?

Thanks,
H20

I've done it many times with no problems or issues.
Label the devce cover to alert others of the 120 vAC.

The potter flows have 2 sets of contacts. connect the 120 switch leg (for the bell) to 1 set and the other set to the module. Use the same voltage rateing for all conductors and you should be fine.

(I prefer "volenteering" as opposed to saveing money.):)
