I don't recall seeing anything but 14x14 (in OH) and 16x16, 18x18, and 20x20 EC spacing increments. If you need 15x15, you'll have to round up to 16x16.
Don't forget that if you're in LH, you need to consider if you'll end up flowing more heads with the EC requirement to flow a min of 5, vrs using room design or 900 SF (vrs 5 EC's at 400=2,000!). -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Richard Lindner Sent: Monday, August 31, 2009 8:55 PM To: sprinklerforum Subject: Mixing sprinkler heads types - EC and standard Is it ok to have a mix of EC and standard heads in a space? Say you are laying out a space that for purposes of discussion are mostly 20x20 bays. Using an EC at 20x20 throw means one per bay. Now off to the side, we have smaller areas, say 14x14 in size. Can I spec a standard head of max throw of 15x15 or should I continue using EC heads in these smaller spaces? thanks, Richard _______________________________________________ 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)
