"subject to" damage<br>

Good morning, Wrenches.<br>
<br>
<br>
<br>
We all discuss the NEC when it comes to ESS but the section in International<br>
Residential Code (IRC) R328 is something to look at carefully. <br>
<br>
<br>
<br>
Easy to miss is the requirement to extend fire alarm systems to garage<br>
spaces where we quite often install the ESS.<br>
<br>
But the section in R328.8 Protection from impact is what worries me as it is<br>
so open ended. Here is what I wrote to a city inspector:<br>
<br>
"I'd like to review this open-ended section of R328 and how you interpret<br>
it, please.<br>
<br>
<br>
<br>
We intend to mount the ESS within an attached garage but we position so as<br>
to prevent damage from vehicles coming into their normal parking space.<br>
Having said that, a vehicle that moved five further feet forward might in<br>
fact run into an ESS. So do you read "subject to" as in normal, due course<br>
or do you consider the very worst scenario / accident?<br>
<br>
And what approved barriers have you seen that comply to your satisfaction in<br>
xxxxx."<br>
<br>
<br>
<br>
What do you all do for R328?<br><br>
<br><br>
