Alarm Check Valves are one of the safety devices that are most commonly found in wet sprinkler systems. But in almost every sprinkler system, the application of these check valves are encouraged.

While most assume that an alarm check valve comes handy to stop the backflow of water within the system, this device performs more than one job. The main purpose of installing this check valve is to ensure that the pipeline remains in good condition by holding the water pressure. With its alarm activation feature it is also used for water motor gong.

Let’s take a look at what exactly an alarm check valve is and how it benefits with its application.

How do alarm check valves fit in fire protection systems?

Fire protection systems that include sprinkler systems have the role of alarm check valve application. Each fire sprinkler system is dependent on an immediate water source in case of fire emergencies.

In most fire sprinkler systems, a combination of municipal water supplies, gravity tanks, etc. are used for supplying water into the sprinkler system’s heads. Even though the multiple water supply lines ensures to offer more reliability for fire protection systems to work properly, another issue may arise is that the potable water may become contaminated.

Water from the fire protection system’s fire hydrant can contaminate the drinkable water or the contaminated water from the sprinkler system can get into the potable water line.

With the application of alarm check valves, this backflow of contaminated water can be prevented and ensure that the water flow remains positive. The fire protection system can work efficiently with the application of these check valves.

The alarm check valve has a valve clapper that comes into function that closes the valve and stops the flow, it also helps in holding the water pressure.

More benefits of Alarm Check Valves in Fire Protection Systems

These valves have an automatic alarm feature that activates when there is a flow of water through the valve. The alarm alerts building occupants, security personnel, and fire department personnel about a potential fire event. The early detection provided by the alarm can significantly reduce response time, increasing the chances of timely evacuation and firefighting.

Alarm check valves are designed to maintain system pressure even when there is a loss of pressure in the water supply. They help keep the fire sprinkler system pressurised, ensuring that the sprinklers will function properly when needed. This feature is crucial for high-rise buildings, where maintaining adequate pressure can be challenging due to height variations and water demand.

Even the installation process of Alarm check valves is simple as it combines the functionality of a check valve and an alarm device into a single unit. This integration reduces the number of components needed and streamlines the overall system design. It also helps save space and reduces the chances of installation errors.

Alarm check valves are designed and tested in accordance with industry codes and standards, such as the National Fire Protection Association (NFPA) standards. By incorporating these valves into a fire protection system, building owners and operators can ensure compliance with regulatory requirements, thereby enhancing the safety of the facility and its occupants.

The automatic alarm feature of these valves helps detect and respond to fire incidents promptly, minimising the risk of extensive water damage. Early detection and quick activation of the fire sprinkler system can help contain and extinguish fires before they have a chance to spread, potentially saving lives and reducing property damage.

Preventing corrosion of pipelines with Alarm Check Valves

In a fire protection system or any sprinkler system, the build-up of high pressure is a common concern. Now, while high water pressure is although preferred, extreme water pressure can cause many issues within the pipeline including corrosion.

When pipes have to deal with constant high water pressure then the pipes can deteriorate due to corrosion. This can typically happen in the joints and weld seams of the pipeline.

In most plumbing pipelines, the pipes may include paint or other liquids that are supposed to be sprayed. Over time, the constant high pressure impacts upon the pipes causing them to form cracks or get loosened at the joints or seams.

However, with the application of alarm check valves, the building pressure can be put into hold that prevents the corrosion of pipes.
