Good point, However, in the 2002 version (which is CT code), section 8.3.3 addresses the same issue. The problem is that we have a room with one SR and one QR sprinkler and the QR has to be replaced. Section 8.3.3.1(3) seems to indicate that SR sprinklers can be used in addition or modification to existing LH systems that have existing SR sprinklers, which I interpret as being the case here. So could a sprinkler that is listed for both SR and QR be installed in a system with SR sprinklers, or would that violate 8.3.3.2?

When existing LH systems are converted to use quick response or residential sprinklers, all sprinklers within that compartment shall be changed. Hope this helps.

I know there are significant discounts, but I doubt if it would be 97.6% to make your "buck a head" The issue is that one sprinkler in the room is scheduled to be replaced. The GB-LO. The existing sprinkler that is scheduled to remain is an SR. The proposed replacement sprinkler is listed for both SR and QR. My question was can an SR sprinkler be in the same room as a sprinkler listed for both SR and QR, per NFPA. The building was built in 1993 and I don't believe the QR requirement was in effect. There are 72 rooms that are impacted by this and another 72 rooms that are not. The other rooms were designed for and most likely remain with SR sprinklers. To make this even more complex, this job has dueling consultants and the other guy didn't even address this issue. My final recommendations will probably include replacing both sprinklers in that room with QR, but who knows if the owner will choose to follow that. Remember the famous quote "You can lead a horticulture, but you can't make her think." Todd G.

If it isn't, then maybe you don't want this guy as a customer..... Seriously, if you're putting new heads in a hotel room, why would you consider anything but QR ? Even if you have the AHJ buy in, imagine the fun a widow's lawyer will have with you when there's a fire death. "Oh, so you didn't meet current standards when you were replacing the sprinkler heads because it was another $2 per room." If you value your retirement assets, you'll put it in your fee and not even ask the Owner. glc _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum
