John, Potter manufactures a release panel that has a zone that can be programmed as an abort circuit or a supervisory zone. As part of our listing we were required by UL to state that the abort circuit on pre-action and deluge systems is not permitted by UL 864.
In my opinion that means that programming the zone to be an abort circuit for a pre-action system would mean the panel would not be in compliance with UL & not be listed for that system. The statue, regulation or code requiring the abort circuit probably also requires a listed panel. So the statue, regulation or code would require something that cannot be accomplished, an abort switch on a listed pre-action panel.

Keep in mind that codes and standards are being written in positive language, i.e. whats permitted vs negative language, i.e. whats prohibited. Remember what state I'm from ?, Missouri.

As Mike stated, UL 864 requires that abort switches shall not be used on deluge or preaction systems. If an abort function is provided and is used on such systems, it would not meet the functional requirements of the test standard and not be recognized as listed. Salvatore Izzo, P.E.

Listings don't seem to have the effect one would assume. We often hear "must be installed in accordance with the listing", or "product listed for the intended purpose". Then we see prescriptive code applications such as deck and balcony sprinklers and smoke alarms used in other then dwelling units. The government can pretty much do as it pleases in the pursuit of "safeguarding building occupants and emergency responders" It's about the hierarchy of code enforcement, it goes something like this; 1. Statutes = The Legislative action, in NJ the "Uniform Construction Code Act" 2. Regulations = The Department or Commissioner rule making, in NJ the "Uniform Construction Code" 3. Codes= The where and when side of the equation, in NJ the 2006 IBC/NJ Edition, amongst many others. 4. Reference Standards = The how side of the equation, in NJ the 2002 Edition of NFPA-13 for example. 5. Manufacturer's Instructions = The specific how for a specific product. 6. Listings = The nationally recognized testing lab that evaluated the product for fitness. I'm sure there are variants at municipal, county and even federal levels. Bottom line if a statute, regulation or code prescribes it then so it shall be.

By this I mean if the local area has adopted 13 and 25 do they also have to take into account ULs rules or just say as long as the device is listed it is good? ________________________________ From: Mike Henke <[email protected]> To: [email protected] Sent: Monday, April 6, 2009 4:45:14 PM Subject: RE: Pre-action abort It is prohibited by UL.

Question two: At what stage of system response do you want to abort? There is no mention anywhere in NFPA 13 about the allowance or disallowance of an abort switch. I just can't see where anyone would be quick enough to get to it if something in the system started an operation anyway. With all the delays already built in to a double interlock system what in the world could another interruption accomplish? I would not be in favor of it. But for the sake of curiosity, what's the application and reasoning behind the question? Craig L.
