Non-Sprinklered Elevator Control Room

Q: In a physician’s clinic that is claimed to be fully protected with sprinklers, the building elevator control room is not sprinklered. Must I install or can I leave it that way?

A: A Business Occupancy building that is fully protected with sprinklers provides you with the ability to meet certain options in the LSC that allows you to take advantage of certain features, such as:

  • Delayed egress locks would be permitted
  • Less restrictions on egress capacity factors
  • Exits permitted to discharge through the interior of the building
  • Less restrictions on hazardous areas
  • Less restrictions on interior finishes
  • Increased travel distances

According to NFPA 13-2010, the standard for sprinkler installation, there are very few exceptions to not installing sprinklers, and allow the building to still be considered fully sprinklered:

  • 2-hour fire-rated barriers around an electrical room
  • Clean agent suppression system installations

However, the 2012 Life Safety Code does have an exception specific to elevator machine rooms. Section 7.14.4.2 says sprinklers shall not be installed in elevator machine rooms serving occupant evacuation elevators, and such prohibition shall not cause an otherwise fully sprinklered building to be classified as non-sprinklered. This is one situation where the Life Safety Code trumps NFPA 13 on the installation of sprinklers.

The 2012 Life Safety Code Handbook continues to provide insight on this prohibition:

The presence of sprinklers in the elevator machine room would necessitate the installation of a shunt trip for automatically disconnecting the main line power for compliance with ASME A17.1 Safety Code for Elevators and Escalators, as it is unsafe to operate elevators while sprinkler water is being discharged in the elevator machine room. The presence of a shunt trip conflicts with the needs of an occupant evacuation elevator, as it disconnects the power without ensuring that the elevator is first returned to a safe floor so as to prevent trapping occupants.

So, no… you should not install sprinklers in the elevator machine rooms.
