We are not sure-- the arch. Dwgs showed only 15 or 20 feet-- the new work is on its own new system (I just realized that exception I mentioned might not apply now)-- we did not think the exist wall was going to be demoed, but it was.

As part of a re-model/building addition, this corridor is lengthened. In the new (lengthened) corridor, quick response, extended coverage heads were designed. The heads 'quick responseness' is based on occupancy and spacing. I know an exception for using standard response in light hazard is when remodeling and existing heads are standard response. In an ord haz area this head at 14X14 is QR, at 16X16 it is SR, but in light hazard it is quick response up to the max (20X20). Any thoughts? _______________________________________________ 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)
