Even I know that IRAS are Individual Retirement Accounts. Didn't know you were required to have them though. And the way mine has been tanking lately maybe I'll try that ESFR thing.

"Guess if you don't know the difference between obstruction rules in ESFR vs. SSU or CMSA's, you might not know what IRAS are either". Like every other designer I'm under the gun to get drawings out the door and sometimes I just don't have the liberty to spend as much time as I'd like digging through the code. I've only been in this field for a couple years and with my office situation you could say I've been thrown to the wolves, I'd like to think those of us with less years under our belt could rely on the forum to help a brother out. Please forgive me if I've taken your post out of context, maybe the deadlines are starting to get to me..

Matt, good catch on the steel column protection too, although I believe IRAS will negate the requirement for them. If you've got a big box, cures switching to control mode might be an expensive cure. What are the issues? -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of George Church Sent: Thursday, September 23, 2010 4:25 PM To: sprinklerforum@firesprinkler.org Subject: RE: Control Mode vs. ESFR What jeff said. And... What exactly are u protecting, and what might be planned for storage? In control mode, you'll need to know what is stored, how it is packaged, storage array, height, etc. You may be looking at a boatload of IRAS. -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Jeff Hewitt Sent: Thursday, September 23, 2010 4:21 PM To: sprinklerforum@firesprinkler.org Subject: RE: Control Mode vs. ESFR With most control mode, you have Group A plastic and pallet storage limitations that you would NOT have with ESFR K14 or K17. If these are areas of concern, then that would be an issue.

What are the pro's and con's with using a Control Mode sprinkler in a warehouse type setting? I've looked at some of the product data sheets and right away you can see the end head pressure is quite a bit lower than the ESFR. Are the obstruction rules the same? Etc...
