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.):)
