Have a 4-story townhouse, sprinklered in accordance with 13R.
Is a sprinkler at the top of an elevator shaft an acceptable trade off for a 1-hour rating of the shaft (in lieu of a 2-hour rating)?
NFPA 13R, 2013 Section 6.6.6 says sprinklers are not required in non-combustible elevator shafts in accordance with ANSI 17.1. The state is says they will not certify the elevator/does not require a certificate in a residential elevator, so there is no confirmation that the elevator code is upheld.
If the sprinkler is an acceptable trade off (or if the sprinkler is elected to be installed in excess of the code requirements) is then a shunt trip and flow switch/heat detector required to shut off power in the event of a sprinkler activation?
