I would think the use of the pull station is more a question than its definition. If the pull station is located in the area of operation of the PA system and is used as a manual release, as long as there is still an automatic release I.E. smoke/heat detectors, and all are wired to the listed release panel, OK. If however the pull station is one of the many required throughout the facility, any one of which activates the alarm system, then it is defiantly not a "Release" device it is an "Initiating" device. Even if that initiates a release panel to open the deluge valve.

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?
