So ask him where in the table (or the text) it say if you're more than the minimum distance away for the ordinary temp sprink that you must use an ordinary temp sprink? He's really reaching.

I understand the standard to state that you can use intermediate or ordinary throughout. Table 8.3.2.5(c) just states that if I am within certain distances to a heat source, I MUST use the intermediate temp sprinkler. The plan reviewer is reading that if I am more than the minimum distance away, I MUST use ordinary. He is stating that Table 8.3.2.5(c) over-rides 8.3.2.1. So, who is correct? That is the question that I need to be able to resolve with the plan reviewer.
