Wet Sprinkler Systems

The First Choice in Life Safety and Fire Protection

A wet sprinkler system is the most common sprinkler system used for life safety protection because of its reliability, effectiveness, and low cost of maintenance. Life Safety Fire Protection is an expert from installation, maintenance, testing including fire pumps and backflow preventers.

How and Why Sprinklers Are So Effective

Overhead pipes contain water under continuous pressure and terminate in a series of closed sprinklers. When a fire occurs and produces an enough heat, sprinklers discharge immediately, preventing fast developing fires from growing, while simultaneously sounding an alarm.

fire pumps are essential

An automatic fire pump provides the pressure and water volume necessary for a sprinkler system to operate correctly in large buildings, high rises, warehouses, commercial or industrial applications. A fire pump is a significant capital expenditure. Whether the pump you need is a horizontal split case, vertical split case, vertical inline, vertical turbine, or end suction, we specify it, install it, inspect it, and test it for operational efficiency. We recognize that a fire pump is a critical piece of the life safety puzzle, and provides affordable inspection, maintenance, and repair to keep your pump operating reliably.

Backflow Preventers

Backflow prevention assemblies are required on potable water lines serving fire sprinkler systems, fire service standpipes, and fire hydrants. These devices prevent the reverse flow of water that could contaminate the water supply. Backflow preventers are also used when sprinkler systems are connected to non-potable public water supplies, especially when the systems are interconnected with alternative sources of water or when antifreeze or other chemicals have been added.
Life Safety Fire Protection designers and technicians will select the proper backflow valves for your sprinkler system, or repair or retrofit a malfunctioning backflow device to keep your system compliant and functioning correctly.

DRY SPRINKLER SYSTEMS

For Cold Environments with Temperatures Below 40°F

For cold environments with temperatures below 40 degrees, these limitations require restricting the system size, including components, such as accelerators and exhausters, and adjusting the number of operating sprinklers. Dry sprinkler system piping does not contain any water. It is charged with pressurized air, or sometimes nitrogen, when a fire occurs and generates enough heat to release the sprinklers, the air in the pipes escapes, resulting in a drop in system air pressure, which allows the dry valve to open and water to flow to the open sprinklers. Life Safety Fire Protection has in-depth experience with the unique requirements of dry systems. Because of the delayed dispersal of water from the dry-pipe valve to the open sprinklers, dry systems place limits on the system design and require a reliable air supply source.

PRE-ACTION/DELUGE SYSTEMS

For High Hazard Occupancies Needing Rapid Suppression Like a pre-action sprinkler system, a deluge system holds back water via an electrically operated deluge valve. However, unlike pre-action systems, the sprinkler heads are always open, and the piping is not pressurized with air.

Pre-Action Sprinkler Systems

Ideal for Water Sensitive Environments

Pre-action sprinkler systems are specialized for use in locations where accidental activation could damage high-value physical assets as in archival vaults, museums, libraries, or data centers. Similar to a dry-pipe system, a pre-action sprinkler system uses piping charged with air or nitrogen under pressure. The pre-action system holds back the water with an electrically operated valve, known as a pre-action valve. Water will not flow into the system until the supplemental fire detection system operates, signaling the pre-action valve to open. This system can allow assessment of the developing fire before water release, potentially saving valuable assets from water damage.

Deluge Sprinkler Systems

For High Hazard Occupancies Needing Rapid Suppression

For high hazard occupancies needing rapid suppression like a pre-action sprinkler system, a deluge system holds back water via an electrically operated deluge valve. However, unlike pre-action systems, the sprinkler heads are always open and the piping is not pressurized with air. When the automatic detection system activates, the valve is opened and water releases through all the heads simultaneously. This massive release of water is needed in areas such as aircraft hangars, fuel loading facilities, power plants, and chemical and hydrocarbon storage or processing facilities. Deluge systems often include foam mixed with water, which creates a protective blanket to control and cool a rapidly developing fire.
