How Do Fire Sprinklers Work During a Fire?

How Do Fire Sprinklers Work in the Event of a Fire?

Fire sprinkler systems are the most common fire prevention method in commercial buildings. Sprinklers work by activating when high temperatures or smoke from a fire trigger them to release water on the flames, stopping them from spreading further. If you’re curious about how your building's sprinkler system works and what options are available for commercial fire sprinklers, read on for answers!

How do fire sprinklers work?

Fire sprinklers are designed to be activated by heat, releasing water to extinguish the flames. The process of sprinkler activation is simple: when a fire starts, heat causes the sprinkler’s metal housing to expand. That expansion triggers the fusible link inside the housing, which allows water to flow out of a small orifice at high pressure through an open onto the affected materials. Some sprinklers contain compressed air that helps spray farther than normal; others use a special mechanism called an actuated pressure switch that closes when exposed to heat and opens when cold again—like flipping a light switch off and on again!

What are the options for commercial fire sprinkler systems?

There are four different types of commercial fire sprinkler systems: pre-action, deluge, high-temperature, and dry pipe. Each type is used for a specific purpose, but they all work the same way. All commercial fire sprinkler systems are designed to detect a fire through heat sensing technology that detects fast temperature rises in certain areas of the building. When this happens, water flows out into those areas and puts out any potential flames before they can cause too much damage or injury to people or property within your building.

Can fire sprinklers cause water damage?

Fire sprinkler systems are designed to put out fires, not cause water damage. That said, there may be some instances where water damage does occur due to a water-soaking drywall and other materials. In these cases, you should seek the help of a professional restoration company as soon as possible to determine whether your home has been affected and what needs to happen next.

If you're concerned about the potential damage caused by a fire sprinkler system in your home or business, here's how they work:
