Hi Thom, I believe the shunt trip has to be installed at the top and the bottom if it is protected with a sprinkler.Also activation can be with a flow switch.Most of the time the heat detector activates the shunt trip.Also top and bottom should be protected with a smoke detector for elevator recall. Check ASME A17.1(2004) Section 2.27.3.2 I hope this helps.

When protecting an elevator shaft of a (Otis Gen 2) or Kone (Eco Space) type elevator where the elevator equipment is contained in the shaft is protection at top and bottom of the shaft required if the shaft is of non-combustible construction? Would Shunt trips (Flow Switch or heat detector operated) be required for both heads (locations) , or just the top of shaft location? My initial thoughts are both top and bottom for heads, and just top of heat detector.
