A pre-action fire sprinkler system is a type of fire suppression system that is designed to minimize the risk of false alarms and water damage in facilities. 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. When a fire is detected, the air pressure is released, and water is supplied to the sprinkler heads to suppress the fire.

Two-Step Process

A pre-action fire sprinkler system is a two-step process requiring two separate devices to be activated before the sprinkler heads release water. The first step is to trigger the fire detection system, which can be done through smoke detectors, heat detectors, 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, and other critical environments.
