The Different Pre-Action Fire Suppression Systems and Their Purposes

The Different Pre-Action Fire Suppression Systems and Their PurposesThere are a few types of fire protection systems, including wet pipe sprinkler systems, dry pipe sprinkler systems, and pre-action fire sprinkler systems. Within the latter product, there are two options: single interlock and double interlock systems. Each type has different features and functions, which we will examine in this post.

Types of Sprinkler Systems

Wet Pipe Sprinkler Systems

Wet pipe sprinkler systems are the most popular sprinkler system because they’re low-cost, low-maintenance, and efficient. The pipes remain filled with water, which improves the reaction time when a fire strikes. This system’s downside, though, is that the pipes, being filled with water, can freeze in cold environments.

Dry Pipe Sprinkler Systems

Dry pipe sprinkler systems don’t carry water in the piping system until activation. Hence, they don’t run the same risk of freezing as wet pipe systems do. When a sprinkler head is triggered, a dry valve opens, allowing water to extinguish the fire. While dry pipe systems are less risky, they lag more than wet pipe systems.

Pre-Action Fire Sprinkler Systems

Pre-action fire sprinkler systems are similar to dry pipe systems, except that the pre-action valve governs the flow of water. They’re a combination of wet, dry, and deluge systems, of which there are two types. The first type of pre-action system is a single interlock, which is triggered by a heat or smoke detector. When this happens, the pre-action valve allows water to enter the piping system.

Double interlock systems require two events to occur before releasing water into the pipes: a fire detection via a heat or smoke detector and an automatic sprinkler activation. These systems are complex, expensive, and high-maintenance, but they’re the best option to protect water-sensitive items.

Pre-action systems are useful in museums, data centers, libraries, freezer warehouses, and other places with expensive equipment that can’t handle excessive water. These systems are also best for healthcare and safety facilities with high-cost machines that can’t withstand water.
