Looking at the fire damage, I find it hard to believe that the
temperature wouldn't have been high enough to trigger sprinklers. But
cruise ships don't go just to warm climates. I remember seeing a
freezer which had been retrofitted into a building and inside the
freezer was a sprinkler head. What that meant was that nothing
downstream of the freezer was protected by the sprinkler system,
because the water froze in the pipes that were inside the freezer.
“Dry” sidewall sprinkler heads can protect the outdoor balcony. These
specialized exterior nozzles contain no water. In an emergency, they
instantly fill with water from primed pipes just inside the wall
But sprinklers aren't the only fire suppression systems available.
