AUTOMATIC FIRE SPRINKLER DESIGN SERIES

The air sampling system may detect particles of combustion before the human eye or nose does and can send signals or warnings before there is actual smoke damage or a fire or before water is necessary.Р”Вeluge systems are similar to preaction systems, in most cases utilizing the same valves, pipe, fittings, alarm initiating devices, automatic sprinklers, and detectors, although all of the sprinklers are open and do not include the heat responsive element.

In these rooms, an air sampling detection system may be more appropriate than smoke detectors. An example of such an area is the data or computer room, where the products of combustion can do as much damage to sensitive equipment as the thermal damage from a fire or the resultant application of water. It is in the system designerРІР‚в„ўs best interest to work closely with the owner and the architect to utilize the type of detection system that is appropriate for each specific area or system. There are many types of detectors and detection systems that can be used with the preaction systems.

Preaction systems areusually less cost-effective than the dry pipe systems and require additional maintenance and testing as well as maintenance and testing of the detection system. In addition to the sprinkler system, however, the preaction system incorporates a detection system. It has a similar valve, and in general the same pipe, fittings, alarm initiating devices, and automatic sprinklers. The preaction system is similar to a dry pipe system. What are the appropriate materials for a wet pipe system? Is interior or exterior corrosion a factor to be concerned about? Is there a possibility or potential for freezing anywhere the water-filled components are installed? The wet pipe system can also include additives such as antifreeze or foam concentrate.Р”Вesign issues relative to the wet pipe sprinkler systems would include the following: It is possible to design these systems for fire control РІР‚вЂњ controlling a fire to the room or area of origin until the fire department arrives and extinguishes the fire fire suppression РІР‚вЂњ actually suppressing the fire or life safety protection РІР‚вЂњ as in residential occupancies. In a wet pipe system, components are arranged in such a manner that, as soon as the heat from a fire operates the heat responsive element of an automatic sprinkler, the water is discharged through the sprinkler to the fire. Wet pipe systems are installed where temperatures will not fall below 40РІВРЏ (4РІВРЉ) and where one of the design objectives is to put water on a relatively small fire as quickly as possible. Its cost effectiveness is based on its having fewer components, requiring less maintenance and testing and having fewer design restrictions than any of the other three types of systems.

The wet pipe sprinkler system is, in general, the most cost-effective, the most versatile as far as protection strategies and pipe installation are concerned, and the easiest to maintain. The four primary systems are the wet pipe system, the dry pipe system, the preaction system and the deluge system.

In the simplest form, these systems include a series of connected pipes and fittings, with valves, alarm initiating devices, and automatic sprinklers that are supplied by a reliable water supply. These systems are designed and installed as prescribed in the National Fire Protection Association (NFPA)Р’В Standard for the Installation of Sprinkler SystemsР’В or NFPA 13. The water from the sprinkler head will cover the area where the fire is located and will continue to operate until the fire department can fully extinguish the fire.Р”Р„lmost all newly built commercial or industrial buildings require automatic fire sprinkler systems for life safety, the protection of the property, the safety of the firefighters, and to minimize business interruption. The sprinkler heads are frangible bulbs filled with a liquid that, when heated, expand causing the bulb(s) to break and the system to release water. An Automatic Fire Sprinkler System is a network of water-filled pipes which starts at your domestic water service line and ends with strategically spaced fire sprinkler heads located throughout your home. An Automatic Fire Sprinkler System is designed to contain and control an unfriendly fire allowing your family the precious time needed to escape from danger and decrease the amount of damage to your valuables from heat and smoke.
