Might get a little messy if it gets cold enough in the winter to freeze in the attic. I've seen it happen in Sacramento, CA.

It may sound odd, but a listed residential sprinkler head will wet everything except the safe below it. The residential head is designed to spray water to the sides to wet the walls and combustibles near the walls (furniture, etc.) to delay their ignition so you can escape from your home. A commercial standard spray pendent (SSP) head with a short throw would work better, wetting the area surrounding the safe if you have enough pressure (at least 7 psi). Just putting a nozzle or a downward-facing quarter-inch pipe directly above the safe would have the flow characteristics you want. That is, you want the water to impact the top and wash down the sides. That will have a very good cooling effect.
The solution to piping in a freezing environment is to use a "dry pipe" setup. That is, the pipe does not contain any water until the system is needed to discharge. This can be accomplished by putting the flow valve in an air-conditioned portion of the house.

Hell, I was thinking of putting out, or at least keeping any fire in the room where the safe was. 
Bobhwry;
Please do look up the U.L. fire standard rating & test procedure for safes. The test criteria specifically has an interior temperature level that must not be exceeded in order to pass the test. That level is 350 degrees fahrenheit. An approximate 100 degrees under the ignition point of paper.
Now, it's true that RSC's, generally speaking, won't pass the U.L. one hour fire test. That's because they do use gypsum wall board for insulation. Wall board is a good flame barrier, but simply does not have the mass to absorb a thermal attack and not pass the heat into the interior of a secure container under the conditions imposed by the U.L. one hour test procedure.

Gahhhh! I hate that stuff. If you use it, have it pre-cut.
