Fire Sprinkler Installation
Fire Sprinkler Installation
Fire sprinkler systems are the first line of defense when protecting lives and property in many types of buildings and applications spanning a wide spectrum of industries. Automatic fire sprinkler systems have been in use since 1874. Many building codes at the federal, state and municipal
levels require the use of sprinkler systems in certain occupancies. The NFPA states that it “has no record of a fire killing more than two people where a sprinkler system was properly operating."
Assurance Fire Sprinklers design, install, maintain and repair automatic fire sprinkler systems. Our experience, expertise and resources will ensure that your job gets done right no matter the size of the facility.
Automatic Fire Sprinkler Solutions
Automatic fire sprinklers are required by many state and local building codes for most new construction. In the U.S., sprinklers are required in all new high rise and underground buildings generally 75 feet (23 m) above or below fire department access, where the ability of firefighters to provide adequate hose streams to fires is limited. The Hotel and Motel Fire Safety Act of 1990 requires any hotel, meeting hall or similar institution that received federal funds including government travellers’ stays or conferences by government agencies must meet certain fire safety conditions. The most visible of these conditions is the implementation of automatic sprinkler systems. At Assurance Fire Sprinklers, we can retrofit your home and commercial places with sprinkler systems designed to comply with all applicable standards, codes and regulations to ensure a greater degree of fire safety for your clients, guests, employees and property.
Types of Automatic Sprinkler Systems
There are several types of automatic sprinkler systems that could be uniquely suited to your building, its occupants and applications within the facility. The experts at Assurance Fire Sprinklers will help you determine the best solutions for protecting lives and property and work with you to design the best system that fits your situation. Our services include the full spectrum of fire suppression systems including consultation, design, installation, maintenance, inspection and repair services.
Wet Pipe Fire Protection Sprinkler System
Wet pipe systems are the most common fire sprinkler system. A wet pipe system is one in which water is constantly maintained within the sprinkler piping. When a sprinkler activates this water is immediately discharged onto the fire.
Advantages to using a wet pipe fire sprinkler system include:
System simplicity and reliability - Wet pipe fire sprinkler systems have the least number of components and therefore, the lowest number of items to malfunction. This produces unexcelled reliability which is important since sprinklers may be asked to sit in waiting for many years before they are needed. This simplicity aspect also becomes important in facilities where system maintenance may not be performed with the desired frequency.
Relatively low installation and maintenance expense - Due to their overall simplicity, wet pipe sprinklers require the least amount of installation time and capital. Maintenance cost savings are also realized since less service time is generally required compared to other system types. These savings become important when maintenance budgets are shrinking.
Ease of modification - Wet pipe fire sprinkler systems are advantageous since modifications involve shutting down the water supply, draining pipes and making alterations. Following the work, the system is pressure tested and restored. Additionalwork for detection and special control equipment is avoided which again saves time and expense.
Short term down time following a fire - Wet pipe sprinkler systems require the least amount of effort to restore. In most instances, sprinkler protection from fire is reinstated by replacing the fused sprinklers and turning the water supply back on. Pre-action and dry- pipe systems may require additional effort to reset control equipment.
Disadvantages to using a wet pipe fire sprinkler system include:
Wet pipe systems are not suited for sub-freezing environments.
There may also be a concern where piping is subject to severe impact damage and could consequently leak.
Dry Pipe Fire Sprinkler System
A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. This air holds a remote valve, known as a dry pipe valve, in a closed position. Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more fire protection sprinkler systems to operate. Once this happens, the air escapes and the dry pipe valve releases. Water then enters the pipe, flowing through open sprinklers onto the fire.
Advantages of using dry pipe fire sprinkler systems include:
Dry pipe sprinkler systems provide automatic protection in spaces where freezing is possible. Typical dry pipe installations include unheated warehouses and attics, outside exposed loading docks and within commercial freezers.
Many people view dry pipe sprinklers as advantageous for protection of collections and other water-sensitive areas. This perceived benefit is due to a fear that a physically damaged wet pipe system will leak while dry pipe systems will not. In these situations, however, dry pipe systems will generally not offer any advantage over wet pipe systems. Should impact damage happen, there will only be a mild discharge delay of about one minute, before water flows.
Disadvantages of using dry pipe fire sprinkler systems include:
Increased complexity - Dry pipe systems require additional control equipment and air pressure supply components which increases system complexity. Without proper maintenance this equipment may be less reliable than a comparable wet pipe system.
Higher installation and maintenance costs - The added complexity impacts the overall dry pipe installation cost. This complexity also increases maintenance expenditure, primarily due to added service labor and fire sprinkler systems installation costs.
Lower design flexibility - There are strict requirements regarding the maximum permitted size (typically 750 gallons) of individual dry pipe systems. These limitations may impact the ability of an owner to make system additions.
Increased fire response time - Up to 60 seconds may pass from the time a sprinkler opens until water is discharged onto the fire. This will delay fire extinguishing actions which may produce increased content damage.
Increased corrosion potential - Following operation, dry pipe fire sprinkler systems must be completely drained and dried. Otherwise remaining water may cause pipe corrosion and premature failure. This is not a problem with wet pipe systems where water is constantly maintained in piping.
With the exception of unheated building spaces and freezer rooms, dry pipe systems do not offer any significant advantages over wet pipe systems.
