Thanks Russell! I thought I had answered my own question using 'pure reasoning' alone :), especially since the original question dealt with needing to differentiate RTI, and "30" must be a UL mandated tolerance. Does NZS541 require UL, or some other testing agency? Is it available (free)? I would like to know if Special Response is required in certain situations, and if so where and why. Thanks again sir, Brad Casterline

These usually have a 4mm bulb. "Std Response" has a 5mm or larger bulb and the "Fast Response" has a 3mm bulb.

I am really more interested in the reasoning for the DEFINITION in NFPA #13, not some box of heads in RTI limbo. Any TC members out there not totally fed-up with me yet? _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list Sprinklerforum@firesprinkler.org http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum
