[RE-wrenches] IRC 328 and ESS...approved barriers and "subject to" damage

[scot.arey at solarcentex.com]

Good morning, Wrenches.

 

We all discuss the NEC when it comes to ESS but the section in International
Residential Code (IRC) R328 is something to look at carefully. 

 

Easy to miss is the requirement to extend fire alarm systems to garage
spaces where we quite often install the ESS.

But the section in R328.8 Protection from impact is what worries me as it is
so open ended. Here is what I wrote to a city inspector:

"I'd like to review this open-ended section of R328 and how you interpret
it, please.



We intend to mount the ESS within an attached garage but we position so as
to prevent damage from vehicles coming into their normal parking space.
Having said that, a vehicle that moved five further feet forward might in
fact run into an ESS. So do you read "subject to" as in normal, due course
or do you consider the very worst scenario / accident?

And what approved barriers have you seen that comply to your satisfaction in
xxxxx."

 

What do you all do for R328?
