Why we give these away.
Because most owners don't hire a fire-protection contractor until something's broken. If we can help you get the answer right before you need us — battery sizing, occupancy loads, hydrant flow, permit scope — you'll remember who did that when you do need a licensed designer. That's the trade we're willing to make.
