FIRE PROTECTION SYSTEM - Design Installation and Setup - A Complete End-To-End Solution
It is an active fire protection method consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system, onto which sprinklers are connected.
The arrangement consists of a system of overhead pipes which are fixed in the ceiling of the room. The pipes are provided at C/C distance of 3 M.
The sprinkler heads are provided with fusible plugs. These plugs melt at a pre-determined temperature. In case of fire, due to heat these plugs will explode and causing a shower of water to fall on the fire source , bringing the fire under control.
PRECAUTIONS TO BE TAKEN WHILE INSTALLING THIS ARRANGEMENT:
-
Pipe should be fitted on the ceiling of the room with ht. not more than 4M.
-
Effective working depends on water supply of the system. Water required for this system could be stored in over head water tank. If stored in the underground water tank provision of the automatic pumps should be made so that the water is supplied to the sprinkler pipes in case of fire.
-
Clubbing the system with alarm system can make the entire Fire fighting system more efficient.
ADVANTAGES: Fire can be suppressed at an infant stage.
Fire sprinkler systems are often the first line of defense in the event of a fire—but only if they are working properly. To ensure that fire sprinkler systems are functional and up to code, it’s crucial that you follow regular testing, inspection, and maintenance schedule. What should that schedule be? Here’s how often fire sprinkler systems should be tested, inspected, and maintained.
How often should you have your fire sprinkler system tested?
There isn’t just one simple answer like “once per year” for when you need to test your fire sprinkler system. There are many different components to a fire sprinkler system, each with its own testing schedule. According to the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, NFPA 25, physical testing must be done:
Fire Sprinkler Component
Testing Schedule
Sprinkler mechanical devices Quarterly
Vane and pressure switch devices Semiannually
Complete fire sprinkler system test, including low flow tests, alarm tests, trip tests, deluge, preaction valves, antifreeze concentration tests, and fire pump tests
Annually
Sprinklers exposed to extra-high temps and harsh environments (Test or Replace) Every 5 years
Gauges (Test or Replace) Every 5 years
Dry sprinklers (Test or Replace) Every 10 years
Fast-response sprinklers (Test or Replace) 20 years initially, then every 10 years
Standard response sprinklers (Test or Replace) 50 years initially, then every 10 years
How often should you have your fire sprinkler system inspected?
Per NFPA, the inspection schedule for fire sprinkler systems is as follows:
Fire Sprinkler Component
Testing Schedule
Gauges (dry, pre-action, and deluge systems) Weekly
Gauges (wet pipe systems) Quarterly
Waterflow alarm devices, supervisory signal devices, hydraulic nameplates, valves supervisory alarm devices, and control valves Quarterly
Pipes and fittings, hanger/seismic bracing, spare sprinklers, and information signage Annually
Internal inspection of sprinkler piping Every 5 years
How often should you have your fire sprinkler system serviced?
If you keep up on the testing and inspection schedule, maintenance is easy. Any time a component fails inspection or testing, it’s time to repair or replace it. Additionally, if components are showing signs of rust, corrosion, or wear, you can note that during your testing and inspection process and replace them. A reputable testing and inspection company will know NFPA 25 and be able to perform all necessary maintenance on the required schedule to ensure compliance.
