I live in an apartment with several fire sprinkler in the ceiling.

If the sprinkler goes off due to fire or malfunction, can I turn it off
after the fire is out? Is it the same valve near the water heater or is
there a different one?

I’m more worry about water damage (to electronics and computers) than fire
damage. Perhaps because I’ve never had a fire before and this is the first
time I moved to a place with fire sprinklers.

Alternately, is there a switch to cut off power to computers or other
devices when it senses water? This would reduce short-circuits caused by
water when the device is powered.

Yes, you could certainly install a water sensing device that would
kill the power to the machines, but you might want to place it as
close to the spinkler head as possible.

If you placed it on the floor (where most water sensing alarms are
usually placed) your systems would probably already be wet by the time
the sensor sensed the water.

You could also place your equipment in racks with a "roof" to keep the
water off of the equipment, but you'd have to deal with ventilation so
that the roof didn't keep the heat in. That could, ironically, cause a
fire! ;-)

Of course, once the fire department crashes through the window with
hoses a-blazing and waters down your whole apartment, all bets are off
as far as keeping your equipment dry.

All that said, if you are that concerned about your equipment, I'll
assume that you already employ off site back-up storage for your data.
You can try and protect the systems from water, but if the fire itself
wipes out the back-up media stored in the shoe box in the hall closet,
you're just as out of luck.
