2016 NFPA 72 requires detection for recall (21.3.7)

-if a sprinkler is provided in the elevator pit, a detector is required.  Smoke detection is preferred, but may not be suitable for this location.  ANSI A17.1 (2.8.3.3.4) requires Type 4 NEMA 250 rated equipment in the pit. 

Does the detector (smoke or heat) and related low-voltage wiring need to be Type4 NEMA 250 rated?
