How Fire Sprinkler Systems Work

Do you have a question about how fire sprinklers work? Read this article to find out. It covers topics such as Pre-action, Deluge, and Wet pipe. Once you understand how they work, you can use them to protect your home or business. If you’re still unclear, here are some essential tips. The first thing you should know is how they spray water. Ideally, they should pour water only in the vicinity of a fire and not the entire structure. Water can cause even more damage than fire.

Wet pipe

In a fire, empty piping increases the time it takes for water to reach the sprinkler system. As water travels from the riser to the sprinkler, it partially fills the pipe, increasing the time to suppress the fire. If the pipe is empty, it can increase the time required to suppress it, resulting in more significant fire damage and property loss.

Wet pipe fire sprinkler systems are the most commonly used fire-suppression methods. They consist of piping systems filled with pressurized water that activates when the fire is detected. They are widely installed in buildings that don’t freeze. They require less maintenance but are not recommended for areas that experience extreme temperatures. Likewise, wet pipe systems are not recommended for areas with freezing temperatures.

A wet pipe fire sprinkler system is comprised of a vertical pipe riser downstream of a check valve and a backflow preventer. It does not have an alarm port or retard chamber but instead uses a vane-type water flow switch that activates an alarm condition after a predetermined period. To eliminate false alarms caused by city water surges, a different pressure switch may be installed above the check valve.

Deluge

Fire sprinkler systems using deluge are highly effective at suppressing large-scale fires. These systems typically use water but can incorporate foam concentrate for special hazards. The combination of water and foam forms a protective blanket of foam. Choosing the correct type of fire sprinkler system for your situation is essential. Below are some common types of deluge systems. Each is useful for different applications. 

A deluge fire sprinkler system is an open distribution pipe network that releases a suppression agent into specific areas. A deluge system activates via a control valve and a dedicated water supply. Once activated, the deluge valve releases water into the pipes and sprinkler heads to inundate the protected area. The deluge system is different from a foam water system, which functions similarly to a water one. Foam water deluge systems are usually connected to a source of fire-fighting foam. This combination allows the water to disperse foam into a large area, thus extinguishing the fire without causing further damage.

A deluge system should be checked and serviced periodically, by building codes and NFPA standards. Regular maintenance of deluge fire sprinkler systems is essential, and fire protection companies handling your installation should follow a regular maintenance schedule to ensure proper functioning. In addition to testing the sprinklers, fire protection contractors will also inspect the valves and other parts of the system, such as the fire alarm system.

Pre-action

Pre-action fire sprinkler systems are more reliable than other types because they do not trigger false alarms and do not cause water damage to the property. However, they require a network of pipes and a reliable water supply to work correctly. Pre-action systems are complicated to install and require experts with extensive experience in sprinkler engineering. New York Engineers specialize in pre-action fire sprinkler systems. Our experienced engineers can provide the information you need to make the best decision for your property.

The most common pre-action system contains nitrogen or air in its piping. Water will only flow through the system if a fire detector detects a fire. This pre-action system is recommended for buildings with freezing temperatures. Nitrogen is safer than air since it does cause corrosion or oxidation. It is ideal for freezer warehouses and water-sensitive environments.

When choosing a fire sprinkler system, it is essential to understand the difference between pre-action and conventional systems. Pre-action systems use two steps to release water. The first step is to activate the valve, and the second step is to close the valve. Pre-action systems have many advantages over traditional systems but can be expensive to install and maintain. In addition, because pre-action systems have so many components, they require regular maintenance.
