Is there any testing or criteria in regards to equivalent rating for a water curtain or deluge curtain when protecting an opening in a rated wall? I have a 3' opening in a 3 hour wall and the architect is trying to see if this can be accomplished with a water or deluge curtain. Thanks, Dewayne _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected]
