We have a two floor building with a hydraulic elevator that is required to have sprinkler protection. Getting to the sprinkler in the pit from first floor is not possible.
My question is, can we feed the sprinkler in the pit from the second floor? Just pick a corner and pipe along the wall? The elevator inspector is telling us that our pipe can not run along the wall in the hoistway. How true is this? Is there circumstances where pipe can run up or down the hoistway, per code? Thanks in advance. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

Let's check ASME A17 (2016)

Kudos to Pete for providing the text from the Elevator Code. Talk to the Elevator Inspector about the project specifics and obtain their concurrence or let the Fire AHJ and the Elevator AHJ hash it out.

Any chance that you could request or propose an alternate using the 2025 edition of NFPA 13 where sprinkler protection is no longer required in most elevator shafts, pits or machine rooms. Personally, I am a big sprinkler advocate, but elevator fires are a pretty rare event and the data may not support all of the effort and expense involved. Even when they happen, the data shows that they are often inside the car (which is a great big obstruction to any sprinklers that may be present at the top of the shaft). From 2017-2021, there were 195 elevator-related building fires in the U.S. (less than 40 per year out of ~400,000 building fires per year). 75% of the time, the fire was contained to the object of origin or the room of origin (mostly the elevator shaft or machine room). About 1/3 of the elevator fires had fire sprinklers present but sprinklers only operated and controlled the fire in 7 fires (less than 2 per year).
