Rick Santorum says yes, Mitt Romney says no, they both say Barack Obama is ruining the American way of life with elevator hoistway sprinklers.
Sorry, I digressed. Actually, shaft provisions in NFPA 13 are mute with regard to valving - that really goes back to local authorities. Here in CA, there is a an elevator division of CAL-OSHA that has jurisdiction over all hoistways and equipment rooms. Their rules supersede provisions of all building and fire codes and referenced standards. It is not uncommon for sprinklers to impact the configuration of alarm systems and to trigger interface with shunt/trip breaker requirements for elevator power. Putting a sprinkler at the top, if it's not a combustible shaft, isn't a common practice anymore, but valving for shut-off is. My guess is that the specific answer to your question lies with the Michigan state elevator AHJ, or the local if there is no such state agency.

Do these need to be provided with a shutoff valve/s?
