Oh, okay. I need to get off my cheap behind and put out some money for the various codes and standards that affect fire protection! Writing a check is comparable to pulling off a finger nail.
Russell Subject: RE: Elevator machine rooms I have an older copy of the excerpt that was part of a code clarification from an AHJ. Like I said in the post, a new edition may have additional or different wording that what I had. Craig L.

To me this could indicate that the valve SHALL be provided, or it could mean IF a valve is provided it shall be outside the hoistway and saying nothing about the machine room. And the struggle with interpretation goes on. Craig, your number 3 line states specifically a valve will be provided. Where did this statement come from? Russell It doesn't say that exactly. From the excerpt I have it says; Sprinkler protection in elevator hoistways, machine rooms or machinery spaces. c. Standard sprinkler protection conforming to the requirements of NFPA 13 may be installed in these spaces, subject to the following. 1. All risers and returns shall be located outside these spaces. 2. Branch lines in the hoistway shall supply sprinklers at not more than one floor level. 3. Shutoff valves shall be provided for each branch line in accessible locations outside these spaces. 4. Means shall be provided to automatically disconnect the main line power supply to the affected elevator prior to the application of water. This means shall not be self-resetting. the activation of sprinklers outside of the hoistway or machine room shall not disconnect the main line power supply (also see Rule 210.5) d. Other pipes or ducts conveying gases, vapors, or liquid and not used in connection with the operation of the elevator shall not be installed in any hoistway, machine room, or machinery space. Typically it's best to contact the local AHJ as there seems to be a lot of disagreement on when or when not to or where to provide sprinklers. But technically there's nothing saying you couldn't go through the room if you put valves on the supply side of the branchline. But we know that's all up to the interpretation of the AHJ.

I need the paragraph stating that sprinkler pipe cannot enter the machine room, supply a sprinkler and then exit through another wall.
