Wal Mart Sprinklers

So following the Covington story, it sounds like the sprinklers went off throughout the store, instead of in the fire area only. Ruined alot of merchandise.
Don’t you think that the sprinklers ought to be zoned ?
You know, ole William McCrossen is the man that got sprinklers mandated.

Sounds like it would ruin just about everything except maybe the fake Crocs and basketballs.

Insurance companies will dictate whether they want to insure the entire merchandise or the entire building.

That's not how they're designed to operate. You fire protect the entire building not sections. Sprinkler heads are triggered by heat as well.

The store’s entire inventory suffered smoke damage, according to Brumfield, though the water damage was limited to the auto section. “The water sprinklers did their job,” he said.
All sprinkler systems in commercial and residential buildings are 'zoned'. You usually only see all sprinklers spraying (deluge) where lots of water is required, like chemical tanks in plants.

I was under the impression that modern systems in large buildings are usually zoned. Maybe this was an older system.

Here's how a sprinkler system in a Walmart works. The entire building is sprinkled, including bathrooms and offices. There are usually 4-6 systems per store, most filled with water with some filled with air in weather exposed areas. When a fire starts in an area, the heat will pop a sprinkler head and start spraying that area only. If the fire is large, it may pop more heads in that area. But it will not spray water in a different area. These systems at Walmart typically have a fire pump installed so you're looking at 150 psi coming out of a 1/2" or 3/4" orifice. That's a lot of water coverage. And a lot of damage.

Either way, the sprinklers are definitely zoned in buildings that big. However, as soon as hot air/smoke/etc pop a sprinkler, every sprinkler in the zone goes off. Probably a good thing as to help prevent the spread of a fire

Walmart should install fire hose towers for use on the customers.

They can be "zoned" with flow switches in multiple story buildings that can trigger the fire alarm but when it comes to protecting the building the sprinkler heads goes off when when heat makes the sprinkler head activate.

There are no electrical controls beyond the flow sensors used to determine when to roll the Fire Department. Heat pops a head in a line that's filled with water (or compressed air to be released and followed with water). Heat below the head - it pops and pours water. No heat - no flow. They are not "zoned" to release together.

Individual sprinkler heads are only triggered by heat. They will only activate when they get to their threshold temperature. The are not electronically controlled.

In addition, that is the nastiest rusty funky smelling water around.... Anything around the water is beyond toast, but I suspect the smoke damage, especially since the auto chemicals and tires may have been involved, is the real destruction.

Former pipefitter here. I can 100% agree with this statement. Nothing worse than being in a lift and hitting trapped water from a drop.
As another poster above mentioned there are typically 4 or 5 systems in a store this size. Fused link or bulb type sprinklers in these systems will only activate when the indicated temp is reached. I have only seen 1 time where an initial water kick from a fire pump blew out additional heads.

This is usually what happens during a fire. Product in the store is exposed to smoke and soot. Any product affected with have to be removed.

I miss seeing him appear on the nightly news at the scene of a fire. Dressed out in bunker gear with his gravelly voice and New Orleans accent while young revelers waved at the camera and frolicked in the background. Good times.
