wireless motion sensor and form C relay

hacksaw
13 years ago

I'm seeking to connect a wireless motion sensor to my hard wired door bell chime. I see that many of the wireless motion sensor receivers have a form C dry contact relay with optional NO/NC positions. Being an "old timer" I'm only familiar with electromagnetic relays, can the door bell wire connect to this type of relay in the NO position? And if not does anyone make such a wireless motion sensor receiver combination that will run a hard wired door chime?
