Thanks, George Medina Jr. -----Original Message----- From: Steve Leyton <[email protected]> To: [email protected] Sent: Thu, Apr 1, 2010 12:22 pm Subject: RE: WINDOW SPRINKLERS You're not allowed horizontal mullions or molding. The glazing can be eparated by vertical mullions so long as each panel has its own sprinkler, but orizontal bumps are a deal-breaker.

Would 2½" mullions spaced at 4'-0" on center with the window height at 9'-0" with no sills) be considered a similar feature? and require separate sprinklers? it seems like it is addressing horizontal rojections only. eorge Medina Jr. _______________________________________________ prinklerforum mailing list [email protected] ttp://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] Put the word unsubscribe in the subject field) __________ Information from ESET NOD32 Antivirus, version of virus signature atabase 4946 (20100315) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature atabase 4946 (20100315) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com ______________________________________________ prinklerforum mailing list [email protected] ttp://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
