two Reliable sprinklers

two Reliable sprinklers

So looking at it from an AHJ side, plan review, and inspection,,,,

I have not seen these sprinklers before;

Just wondering on the plan review side and inspection/installation side anything special to look for:

I am use to the Tyco attic, and these seem about the same. No water delivery time required, except if the dry systems requires it:::

The combustible concealed sprinklers, seem to have a lot of rules to follow on installation::

Once again anything special to look for on plan review, and installation??:::

Thank you

RE: two Reliable sprinklers

The one item that first comes to mind is the mixing of these special application sprinklers and standard heads. I have had conversations with Reliable sprinkler engineers and the bottom line is that unless the whole attic can be done with just these Reliable Special App heads a different avenue must be taken.
in short, if the design shows these special app heads with a standard reliable type sprinkler and/or a different brand special app head/standard type sprinkler then it is not exactly compliant.
be aware that TYCO and Viking have similar products. Viking I have little experience with and Tyco have many more options of special app attic heads making the design easier (and overcoming the issue I first pointed out).
