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?

Im more worry about water damage (to electronics and computers) than fire
damage. Perhaps because Ive 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.

@Bob:

The fire sprinkler system in your apartment is being inspected on an
annual basis by the local AHJ... So a "malfunction" is not very
likely
to occur... You do realize that each individual sprinkler head must
"activate" by having a bi-metal piece or glycerin syringe melt/pop in
order for water to flow from it... It is not a "deluge" type system
unless
it is very very very old or deployed in special situation like a
theatre
stage...

As to turning off the sprinkler system after a fire, the fire
department
will take care of that before they turn the building back over to the
owner during the overhaul...

Well, your new home is much safer than your previous domiciles as
you will not be burnt to death in a fire and have a much longer escape
window during a fire event in a sprinklered building than in one
without...

As to your question about water damage to electronics, that is what
happens when things get soaking wet -- this is many more times
likely to happen from a water leak from a tenant on a floor above you
than from sprinkler leaks or an actual fire... As someone else
stated,
get renter's insurance... There is already a device which will shut
off
power when water logged devices short circuit, it is called a circuit
breaker... However I wouldn't worry that much about it, as during a
serious fire event in a building the fire department generally shuts
off
the power to the building to make the fire fighting operations safer
and
remove electrical short circuiting as a source of ignition...

And, believe it or not. most consumer electronics/PCs (with the possible
exception of of LCD displays), handle getting wet pretty well, as long
as it is not immersed and the water is clean. I've salvaged plenty of
stuff that was left outside, or under an accidental sprinkler discharge.
Unplug, hold upside down to drain, field-strip it, blow it out gently
with an air source, and leave in a sunny window for a day or three. May
have to use a little electronic spray cleaner on any pots or circuit
boards that show water trails, and replace a popped fuse here and there,
but it usually still works.

The odds go down with a sewage leak, or plumbing supply line leak that
came down through drywall and insulation, of course. But my old-school
Sherwood stereo receiver in the other room came out of a dumpster, where
previous owner thought it was ruined because a cat ****ed in it.
Cleaning and new fuses, and it lit right up and sounds fine.

Probably not. Except for a couple parts near where the cord comes in,
the voltage inside a receiver is about 12DC or lower. Even the 110v

Water is clean? you ever smelled water that has been sitting in
sprinkler pipes for a long time? That water is anything *but* clean.
Certainly not "potable" even.

But like I said in my previous post, it's not something that the OP
should be losing sleep over; odds are far higher of having a domestic
water leak than an unneeded sprinkler activation incident.

It's not like in the movies and TV where you see all the sprinkler heads
start spraying water at the same time. It doesn't work like that if that
worries you. Only the sprinkler head tripped by flames releases water.
Many systems are dry, meaning there is no water, only compressed air in
the pipes which keeps the main water valve shut until a sprinkler head
is activated by fire. The wet pipe systems have to be drained to flush
them out on a regular basis to keep crud out of them, the dry systems
don't have that problem and the maintenance folks have to keep an eye on
the air pressure in the system which is usually remotely monitored
through the alarm system. If you are in a multi-floor apartment building
, each floor may have a maintenance closet where there is a valve for
your floor.

Dry systems are a bitch to maintain and they tend to rust faster than a
wet system due to the oxygen and moisture contained in the pipes. I used
to keep an eye on a system that had two risers and compressors. I can't
tell you how many times I had to scramble to trouble shot a compressor
before it tripped and charged the system. Rust, pin holes, bad
connections... dry systems tend to develop small leaks and the
compressors have to work harder and harder to keep up as the system gets
older. If the diaphragm trips unintentionally due to a drop in pressure
there is always a chance some of the heads may fail due to the hammer
effect.

We have two freeze prone areas at work. They have a glycol system. The
pipes are filled with an anti-freeze solution and there is a reservoir tank
attached to it also in the last heated section. This was recommended by
both the sprinkler company and the insurance carrier.

The dry systems I'm familiar with had compressed air dryers for the
compressors to keep moisture at a minimum. I've repaired many a
compressor and air dryer system. The dry air was to prevent the exact
problems you mentioned. An engineer I was working with on the first
indoor cooling tower type setup in The Southeast, bumped a sprinkler
head with his hardhat and lucky for us it simply leaked so I tend to
believe the things are quite tough as far as resisting water hammer.

Around here, all new dry fire suppression systems must be tested for a
minimum delay from when the sprinkler head is tripped to when the water
starts spraying at the furthest head. This testing guarantees the system
will be wet inside. Blow the lines all you want but you will never get
all of the moisture out.

+1 to what Nate said...

The expenses involved in all the additional sensors as well as the
special valves that each "dry zone" needs as well as the dedicated
air compressor for each zone required and emergency power to feed
it are enough of a barrier to reserve the use of "dry sprinkler"
systems
to sections of a building where environmental concerns like freezing
temperatures are a factor in the fire protection system design like
loading dock areas, parking areas and entry ways and stairwells
which are unheated...

Get you facts straight! Dry pipe sprinklers are only used were there
is a danger of freezing. They are more expensive to maintain because
the condensate traps have to be drained monthly. The compressor for
the piping air adds cost and the differential dry pipe valve is much
more expensive than the Alarm Check Valves used on wet pipe systems.
Preaction only systems are only found were the damage from water might
well exceed the damage from a fire. Examples include museums,
historic library collections, fur storage, paper supply storage, and
similar occupancies. If you are thinking of a combination preaction
dry pipe system those are extremely rare and are found only in areas
exposed to freezing that are so large that an ordinary dry pipe system
would take too long to deliver water to the fire.

It's not like in the movies and TV where you see all the sprinkler heads
start spraying water at the same time. It doesn't work like that if that
worries you. Only the sprinkler head tripped by flames releases water.
Many systems are dry, meaning there is no water, only compressed air in
the pipes which keeps the main water valve shut until a sprinkler head
is activated by fire. The wet pipe systems have to be drained to flush
them out on a regular basis to keep crud out of them, the dry systems
don't have that problem and the maintenance folks have to keep an eye on
the air pressure in the system which is usually remotely monitored
through the alarm system. If you are in a multi-floor apartment building
, each floor may have a maintenance closet where there is a valve for
your floor.

I think we clarified that in later posts. I've only seen dry pipe
systems in commercial/industrial settings.

The OP should ask the building to change to a dry pipe
system. That way, when the fire happens, the sprinkler will
spray dry all over the room. Doing much less damage.

That's the old school way. Now they typically have a groove cut in the
stem of the valve which activates a "tamper switch" which reports to the
FA system (and therefore the central station) when someone closes a
normally open valve, or opens a normally closed one.

If you don't have tamper switches, the chain/cable used to lock the
valve open is supposed to have a breakaway but in practice that doesn't
always happen. The key (actually, several sets of keys - including the
ones to access the fire alarm panel, and a master key to the building)
to the lock should be in the key box in the fire control room which the
fire dept. has access to.

Typically the sprinkler risers are in the stairwells, with the floor

those valves, unless you like having legal problems. The valve controls
all the sprinkler for the whole floor, therefore if the fire is out in
your apartment but not in your neighbor's, and you cut the water off,
well, you get the idea.

I too share your concern on a visceral level about having all that
pressurized water in pipes above all my valuables, but honestly, the
sprinkler system is probably better maintained than the domestic water
supply. So long as you don't bust a sprinkler head (it happens,
especially with non-concealed types) you don't have a lot to worry about.

The code in our state (maybe nation?) is that the sprinkler heads have to be
changed every 50 years.

They can go off accidently, but it is very rare. I've seen sprinkler pipes
banged by errant fork lift drivers and nothing happened. Except one time,
many years ago. To guys were done for the day and were racing back to the
charging station. They had the stand up type of lift and were playing
Chariot race, like Ben Hur. One went under a mezzanine with his fork partly
raised and he took out a 3/4" pipe. Lots of water in the storeroom that
night.

At our business, they put in a new system in parts that had no sprinkler and
changed out some 50 year old heads. Never had one go off. The system is
tested twice a year.

Maybe if you bang the pipes, but if you hit the head there's a good
chance.

I've seen it happen several times, once in a hotel room where somebody
hung a clothes hanger on the head. (Doh!)

That little glass piece is fragile - it handles a good compressive
load but any sideways pressure will trip it, and an impressive amount
of water will come out.

@Nate:

What you are discussing in the stairwells is NOT the sprinkler riser
pipe but merely the fire hose standpipe riser which is an entirely
separate feed down the the fire pump room in the building (and in
some buildings the riser pipes are dry and require a fire pumper
truck to hook up at the external connection point after the engine
has established a water supply from a fire hydrant to feed water
into them) to allow the fire crews to obtain water to fight fires on
the upper levels without having to drag hoses in from the ground
floor...

Typical fire hose standpipe risers are 4" to 6" in size... The main
sprinkler piping in a building is generally 8" (small building) or
better with main supply pipes serving large sections of the building
being at least 12"...

Around here generally the floor control valves and the hose valves are
tapped off the same pipe, or at least that's what I'm used to seeing.

Sprinkler heads go off one at a time. It's not like the movies where
a fire by one head makes the whole room rain. Only the heads that get
hot enough will start spraying. If that happens you'll be glad they
did.

They don't trip accidentaly. BUT! They are pretty delicate when it
comes to being bumped, and they dump an impressive amount of water
when they go off. So you do want to be VERY careful when near them.
I've seen people hang a clothes hanger on them with disastrous
results, or your kids could toss a frisbee, etc. You'll be liable for
the damage if you cause it.

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.

No. You cannot control the sprinklers. They are controlled at a
central location in the apartment building, on a floor-by-floor basis,
or a building-by-building basis, depending on the size of the
building.

You don't want some idiot turning off his sprinklers out of some
misguided notion that his electronic toys are worth more than human
lives.

That's the risk you run. Make sure you have renter's insurance that
covers all your stuff. Keep important papers in a water-tight fire
safe. Keep backups of your important data off site.

There are some devices designed to protect against basement flooding.
However, they may not work if it's just "raining." Also, even if your
computer is off, if it gets wet, you can forget about ever using it
again.

In my experience (admittedly not with any recent computers) that isn't
necessarily true.

If it is powered up when it gets wet, damage can occur as jolts flow
where they shouldn't. But if not powered up, you can usually dry them
out and they work fine.

We used to take keyboards apart and flush them with distilled water,
back in the days when they were expensive.

Yes the switch you are asking about is called a shunt trip. It's name
comes from the shunting of some of a breakers current to a solenoid
inside the breaker that trips the breaker to the tripped position even
though the current flow has not exceeded the breaker's rating. The
shunt switch can take many forms including a manually operated push
button. Automatic shunt trips are now required in elevator machine
rooms and shafts in order to avoid any erratic operation that might be
caused by sprinkler discharge effecting the elevator controls. That
is needed because indoor elevator controls are not built to be
waterproof. These use a heat detector to shunt the current to the
solenoid and trip the breaker. The heat detector used has a lower
actuation temperature than the sprinkler heads used in those spaces.

That said I believe you would find the cost of parts and installation
a large price to pay for a scenario that is not likely. Keep in mind
that smoke can do as much damage to delicate electronics as water so
suppressing the fire quickly; which is an automatic sprinkler systems
reason for existence; will do much to raise the chance of successful
salvage of the electronics you are trying to protect.

I've installed a lot of shunt trip breakers and contactors that power

They have tools out there to stop the water from flowing. Check out
www.quickstoptool.com. By the time the fire department gets there,
locates your main water shut off valve and the system drains, you will
have plenty of damage inside that could be avoided if you have a shut off
tool on hand. Since most sprinklers are serviced, a malfunction is
unlikely, its vandalism (whether intentional or not) that a lot of times
causes unnecessary damage. As I say all of this, the benefits to having
sprinklers outweighs the risk of potential damage. But for peace of mind,
there are tools out there that anyone can use. And if I was living on the
bottom floor, I would buy my neighbor one who lives above me incase their
sprinkler head gets damaged.

You might check in with the local fire inspectors. It has been about
30 years since I dealt with residential sprinklers (and even then only
peripherally) but it sticks in my mind that the first responders just
used a wooden shim like you use to level windows. I could be VERY wrong,
though.

yes, quite possibly. You'd have to look at the sprinkler heads and
determine how to stop the water from flowing once the element pops
however. Some of them use a glass element that breaks, others use a
metal fuse link.

If this is a multi-story building, there ought to be a valve in one of
the stairwells feeding the entire floor, at which the water can be shut
off. However, touching that valve in an other than official capacity
can cause lots of (legal) problems. I would be very very hesitant to
touch that valve under any but an emergency circumstance (e.g. someone
knocked a head loose, you knew 100% that there was no fire, and you were
on the phone with 911 or the fire dept. and they asserted that it was OK
to shut that valve.) Additionally, it might be a looped system where
you have to shut two valves in two different stairwells to isolate a floor.

Doubt you can turn it off. If the sprinkler does go off, you have more

In most cases, the valves are locked in the open position. This is to
avoid people turning them off and rendering the sprinkler system useless
when needed. You can even be arrested in some jurisdictions.

The fire department or the building maintenance can turn them off.

That's the old school way. Today newer buildings tend to have valve
position monitor switches tied into the fire alarm system that will
alert the building personnel if a valve is tampered with (in fact the
common term for them is "tamper switches.")

My understanding was that there should be a "breakaway" somewhere in the
chain or cable that would allow someone to shut the valve in an
emergency by applying greater than normal (but not outside the range of
normal human strength) to the handwheel. However I've seen plenty of
valves locked open with what appeared to be ordinary chain.

This is to
avoid people turning them off and rendering the sprinkler system useless

Agree 100% with the above.
