Is this pull station located at the riser next to the PA valve to comply with NFPA 13, 7.3.1.2 or is it somewhere else? How is it tied into the PA system, I seemed to miss that description.

Sprinklers are for property protection and not life safety. This has been drilled in to me through training" He said the fact that the Potter website references NFPA #72 stating that failure of the (releasing panel) shall not impair the operation of the sprinkler system proves that.....(I don't get that either) Well now I know, and here I have been thinking that what I do is important. But the pull station/releasing device problem is solved at least.

I am the contractor and the EOR is saying it in is in our scope of work, no big deal. The issue is that he didn't want the "releasing devices" tied into the alarm system and wanted them installed in accordance with NFPA #13. The "RD" specified by the AHJ to be electric (this is the AHJ's brainchild/requirement) and that it should electrically release the solenoid on the Preaction valve. He said NFPA #72 doesn't apply to the "RD's". I said no way. BTW, the AHJ said no way as well. He wants the "Pull Stations" monitored for integrity, so if there is a bad wire, etc they get a trouble signal.

By NFPA 72 definition a pull station is an initiating device. Its actuation initiates a response. So in the case of the preaction system it is an initiating device since it initiates opening of the PA valve. Whatever it's called, whether it be pull station or releasing device is pretty much irrelevant. Craig L.

He is calling it a releasing device and not a "pull station" by definition. ???thoughts?
