What It Is and How Many Types are? Sprinkler system is the most widely used fire protection system. Everyone needs to know about the automatic fire sprinkler system and its types because it helps to put out 96% of the fires alone. You must have a fire sprinkler system solution to protect your commercial, residential, industrial buildings. It helps to save your life, property, and minimize business downtime. It is a cost-effective active fire protection system that consists of automatic sprinkler heads, valves, alarm initiation devices, a series of connected pipes with fittings, and a water supply system. There are different types of sprinkler systems, and the selection of sprinklers will depend on applications. To know more about it, check below. Automatic Fire Sprinkler System An automatic fire sprinkler system is a fire protection method. When the head of this system detect the fire, then initiate the alarm and let the water source open to discharge water immediately. These sprinkler systems play an essential role in minimizing fire damage at a facility. It is chemical-free and definite. Types Of Automatic Fire Sprinkler System The automatic fire sprinkler system has four types: wet pipe systems, dry pipe systems, Pre-action systems, and deluge systems. They are available for different application activation processes. The operation system of each type is the same. A brief overview of these four types: 1.Wet Pipe Sprinkler Systems The wet pipe system is the most common and used. It is effortless and reliable. Wet pipe systems are composed of closed automatic sprinkler heads, valves, pipes with fittings, and an alarm check valve components. This system has pipes that perpetually contains pressurized water. It activates due to the presence of a fire. The sprinkler heads located at the ends of the lines will open when exposed to enough heat and release the water inside. When the sprinkler bulb temperature crosses its specified temperature, it releases water immediately to put out the fire. Pros The system makes the activation more specific and works without interruption in the building except for the fire-rated zone. Cons The water could freeze in this system and make the system inoperable. Dry Pipe Sprinkler Systems The dry pipe sprinkler system is used in low-temperature areas where water freezes in the pipes. So, the tubes are filled with pressurized air or nitrogen rather than water. This system is recommended where the temperature is below 40˚F (4.44 ˚C). The pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. Then, the air escapes, and the dry pipe valve releases. Pros The systems are ideal for unheated buildings, parking garages, and warehouses. It also protects areas that store sensitive equipment to minimize damage. Cons The system is relatively expensive. Pre-Action Sprinkler System In a pre-action system, the water is restrained by a pre-action valve. When flame, heat, or smoke detects, the valve opens. Before activation, it follows two stages of the activation process. In the first step, the signal is sent to the control panel for opening the pre-action valve after detecting the fire. Then the system permits the pre-action valve to automatically open and admits water into the pipe network. In the second step, when the fire generates a sufficient quantity of heat to cause one or more sprinklers’ operation, then the water discharges. Pros The system is useable in sensitive areas to avoid accidental discharge and minimize water damage. Cons The systems are complex that leads to high installation and material costs Deluge Sprinkler Systems A deluge fire sprinkler system is the same as a pre-action system, but the sprinkler heads are open, and the pipe is not pressurized with air. It is known as a quick application of a large amount of water in an emergency. The system has sprinkler heads with fixed spray nozzles that can discharge water rapidly whenever needed. The detectors send a signal to the panel, and the deluge valve electrically or hydraulically triggered and supplied water to the nozzles to discharge. Pros The system is applicable for high hazard areas such as power plants, aircraft hangars, and chemical storage or processing facilities. Cons Water will pour out of every single fire sprinkler connected to that system because all of its head open and connected. Conclusion Automatic fire sprinkler systems are a part of an essential system because they help you protect your life and property against fire. There are numerous types of sprinkler systems, but these four types are widespread. We hope that the report gives you full information and helps you choose according to your need.
