It uses a combination of water and air pressure to activate the sprinkler system and suppress a fire. The system consists of a network of pipes connected to a water supply and equipped with fire sprinkler heads at designated points. The pipes are filled with air under pressure, which holds back the water from the [fire sprinkler heads](https://blog.koorsen.com/what-are-the-different-types-of-fire-sprinkler-heads). When a fire is detected, the air pressure is released, and water is supplied to the sprinkler heads to suppress the fire. [![Questions!

The first step is to trigger the [commercial fire alarm system](https://www.koorsen.com/products-services/fire-protection/fire-alarm-systems/), which can be done through smoke detectors, [heat detectors](https://blog.koorsen.com/what-is-a-flame-detector), or a combination of both. Once the fire detection system has been activated, water is released into the pipes. The second step is for the fire sprinkler head/s to activate and suppress the fire. One of the main benefits of a pre-action fire sprinkler system is that it provides a high level of reliability and protection against false alarms. The two-step process ensures that water is only released in the presence of an actual fire, which reduces the risk of water damage from false alarms. ## **Highly Customizable and Versatile** In addition to its reliability, pre-action fire sprinkler systems are also highly customizable, making it easy to design a system that meets a facility’s specific needs. They are also versatile and can be used in various applications, including high-risk areas, [data centers](https://blog.koorsen.com/2015/12/data-center-fire-safety), and other critical environments. ## **Contact Koorsen Fire & Security** Pre-action [fire sprinkler systems](https://www.koorsen.com/products-services/fire-protection/fire-sprinkler-systems/) are an effective and reliable solution for [fire suppression](https://www.koorsen.com/products-services/fire-protection/fire-suppression-systems/) in commercial and industrial facilities.
