I've seen a few false activations...they were in pizza kitchens. I guess there is a lot of hot air that escapes when they open the oven.

NFPA 13 allows the use of intermediate temp heads throughout, so it is just easier to go that way.

Really no need to worry as the fan is pulling the hottest are up the duct and there will be cooler air from other areas moving into the area to replace the exhausted air. I've never seen a sprinkler go off in a kitchen unless there was a fire that was outside of the hood perimeter or one that escaped the hood perimeter because the hood system failed to extinguish the fire.

    We just keep the entire kitchen at 200.  No point in mixing
    sprinklers.  Confusing to fitter and maintenance later.

    Thanks Travis. How far away from the hood until you’re back to
    155 degree heads?

    50° above highest expected ambient.

    We just do 200F sprinklers in all areas as a minimum.

        What are the guidelines for high temp/intermediate temp heads
        spaced around the perimeter of a commercial kitchen hood? I
        didn’t see anything specific about it in 13.
