My main concern was that some uprights are spaced directly above the lights and it appeared that there was a large dead space below, but it appears the consensus is that it is ok with upright only. Thanks again guys.

According to NFPA-13 (2007) Sec. 8.6.5.3.3 it seems I need verage under a 4' wide fixed obstruction. My sprinklers are 5' above the ghts. Do they need to have ceiling tiles in place around it or is there a lution I am missing. Any help would be greatly appreciated. eorge Medina Jr. 3-236-1640 _____________________________________________ rinklerforum mailing list [email protected] tp://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum or Technical Assistance, send an email to: [email protected] o Unsubscribe, send an email to:[email protected] ut the word unsubscribe in the subject field) _____________________________________________ rinklerforum mailing list [email protected] tp://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum or Technical Assistance, send an email to: [email protected] o Unsubscribe, send an email to:[email protected] ut the word unsubscribe in the subject field) _______________________________________________ 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) ______________________________________________ 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)
