Pre action system fire protection

What is a preaction system? In some instances, the pre-action fire sprinkler system may be set up with a double interlock in which pressurized air or nitrogen is added to system piping. The purpose of this feature is two-fold: first to monitor piping for leaks and second to hold water from system piping in the event of inadvertent detector operation.

With the proper engineering and maintenance, it is a reliable way to eliminate fire hazards and keep both your business and employees safe. But rather holding water from piping via pressurized air or nitrogen, pre-action sprinkler systems restrain water with an electrically operated valve, known as a pre-action valve. The difference between a deluge system and the pre-action system is that in the pre-action system , the pipes are filled with compressed air and the sprinkler heads are all close and water is held back from the piping by a pre-action valve.

Pre-action fire sprinkler systems employ the basic concept of a dry pipe system in that water is not normally contained within the pipes. Valve operation is controlled by independent flame, heat, or smoke detection. A double interlock system has two events that must occur: 1) fire detection from a heat or smoke detector and 2) automatic sprinkler operation. Once one of the above occurs, the pre-action valve operates, allowing water into the system piping, essentially turning a dry system into a wet system.

A fire sprinkler system is an active fire protection metho consisting of a water supply system , providing adequate pressure and flowrate to a water distribution piping system , onto which fire sprinklers are connected. In a pre - action system , water is not normally contained within the pipes themselves. Instead of holding water from piping via pressurized air or nitrogen, pre - action systems restrain water with an electrically operated pre - action valve. Protecting Irreplaceable Assets with Pre - Action Sprinkler Systems All businesses must protect their company’s assets.

Similar to a dry-pipe system , a pre - action sprinkler system uses piping charged with air or nitrogen under pressure.

The valve is opened when flame, heat, or smoke is detected. Two things must happen before a pre - action sprinkler system releases water. Preaction fire sprinkler systems are best used in locations where accidental activation resulting in water damage could be costly (ie: data centers). First, the system must detect a fire (normally by way of smoke or by way of heat) and then release the pre - action valve allowing the water that is held back to flow into the piping system. The difference, however, is that water is held from piping by an electrically operated valve, known as a pre - action valve.

A wet-pipe system contains water under pressure at all times and utilized closed. The water is prevented from entering the piping via pressurized air or nitrogen, and an electrically operated valve, known as a pre - action valve. Pre Action System Fire sprinkler systems play an integral role in suppressing fire from the onset until firefighters arrive. The pre - action system is one of several that is effective in fire suppression.

We design and install these systems to ensure they are always efficient and easy to maintain. With pre - action fire systems, a specific sprinkler head that detects heat or fire is opened. If neede other sprinkler heads will open and be put into use. Our prefabrication operation allows for an added level of precision and efficiency as each system is preassembled in-house for a quick and easy installation on the job site.

The system coverage can expand as needed. Every system installed is tested thoroughly to ensure it is working correctly and meets fire protection code. In addition to building and installation, we provide maintenance, inspection, and 24-hour emergency services for fire protection systems. This valve is opened by a fire detection system installed in the same areas.

A pre -alarm of a possible fire allows time for alternate fire extinguishment prior to a sprinkler discharge.

A pre - action system incorporates a failsafe network to protect against accidental activation. These systems combine features of dry, wet, and deluge systems. They are typically used in areas where valuable materials or artifacts are stored such as museums or data storage facilities.

The benefit to the pre - action system is that the water is not stored in the sprinkler pipes, reducing the risk of pipes leaking and causing damage to the IT equipment. With so much at stake, it pays to go with a recognized leader in fire protection. VFP handles all phases of fire protection , including pre -planning, engineering and design, coordination, project management, and installation. We also specialize in testing, inspection, repair and maintenance of these systems to assure continued proper functioning.

The qualified professionals at VFP Fire Systems recognize that each customer has unique needs. Pre - action systems are specifically designed to provide controlled protection.
