This makes these types of fire sprinkler systems ideal for applications such as museums, server rooms, libraries, and data farms. Pre-action fire sprinklers two-step activation process helps prevent accidental system activations. Once, the fire sprinkler opens water immediately pours onto the fire. Next, a fire sprinkler head must detect an increased temperature to indicate a fire. First, a heat or smoke detector must detect a fire which then sends a signal to open the pre-action valve. Activating pre-action systems is a two-step process. Pre-action fire sprinkler systems contain pressurized air or nitrogen instead of water. Unheated warehouses, parking garages, and attic spaces often utilize this type of fire protection system. Since dry pipe fire sprinklers contain no water, they’re ideal in areas subject to freezing temperatures. Then the activated fire sprinkler discharges the water. This causes the dry pipe valve to open and floods water into the dry pipe fire sprinkler system. When a fire sprinkler detects a sudden temperature increase it activates and the air pressure drops in the system. The air pressure holds a dry pipe valve closed and prevents water from entering the system. Unlike wet pipe systems, dry pipe fire sprinklers are filled with nitrogen or pressurized air. Wet pipe fire sprinkler systems are found in office buildings, schools, and high-rise buildings with ordinary hazards. When a fire sprinkler element reaches a designated temperature, it breaks and releases the water. The process to activate a wet pipe fire sprinkler is simple. This prevents the water in the pipes from freezing. Since water is present in the system, facilities must maintain a temperature of at least 40 degrees. Wet pipe fire sprinkler’s pipes contain water and are the most common type of fire sprinkler system. The main difference between these types of fire sprinkler systems is their applications and how they activate. Each of these systems helps prevent flames from spreading and reduces fire damage. Wet pipe, dry pipe, pre-action, and deluge are four types of fire sprinkler systems. What are the Different Types of Fire Sprinkler Systems?
