If a site visit is required to your property, our Project Estimator will reach out to schedule an appointment to see the conditions for your new or existing sprinkler system.
The most common of all fire sprinkler systems, wet sprinkler systems consist of water that is constantly maintained within the sprinkler piping. When a sprinkler activates, this water is immediately discharged onto the fire.
Wet sprinkler systems are best used for:
Churches, Schools, Event Centers, Retail stores, Healthcare Buildings (Senior living/assisted living), Multi-Living and Dwelling Units (apartment buildings, condominiums, and hotels)
Dry Systems are typically used when wet pipe systems can't be used because of the chance of freezing temperatures or when temperatures cannot be maintained above 40 degree Fahrenheit.
Dry Sprinkler Systems typically have pipes pressurized under air or nitrogen, have a dry valve, and must be pitched so water doesn't freeze within the pipes.
Dry sprinkler systems are best used for:
Garages, Loading Areas, Unheated Warehouses, Cooler Storage, Outdoor Enclosures
Anti-freeze systems are are typically used in wet pipe systems to keep the water from freezing. In places where the temperature may drop below 50 degrees, an anti-freeze loop can be added to the sprinkler pipes.
Anti-freeze systems must only use anti-freeze listed for the purpose of use in fire sprinkler systems.
Fire Pumps are typically used when a building's water source does not have adequate water pressure for the protection of a system. Even residential sprinkler systems may need a small fire pump.
Fire pumps are typically used in:
Nursing Homes, Multi-story Apartment buildings, Warehouses, etc.
A standpipe system is a fire hydrant system inside a building. It allows fire fighters to connect hose to a water source to manually fight a fire without having to run the hose from the outside into and through the building to the fire. Standpipe systems share the water supply with the fire sprinkler.
Applicable codes: NFPA 13, 14, & Life Safety Code.
NFPA classifies standpiupe systems into 3 types: Class I, II, III
Fire pumps are typically used in:
Tall or very large buildings.
