We studied on the design of a sprinkler control system that communicates with the administrator's mobile through a wireless communication network and a sprinkler unit that sprays water on the vegetation area. This sprinkler control system consists of a communication module that receives an operation signal for the operation of the sprinkler unit from the administrator's mobile, and a control module that controls the sprinkler unit according to the operation signal received through the communication module. It is also designed to control sprinkler units by measuring temperature, humidity, light intensities, vibration and field images in the vegetation area in real time through sensors and camera for each of them and comparing them with established limit criteria. The sprinkler allows the administrator to control the sprinkler more easily because the administrator operates the sprinkler through the mobile from a distance, and emergency situations occur and can respond quickly.

National Fire Safety Code 103 regulates that all operating sprinkler in design area must be discharged 1 bar or more pressure and release 80 lpm or more flow rate as minimum criteria. NFSC103 also provides that the number of operating sprinkler in design area is 10, 20, 30 according to the building classification and the total flow rate is 800, 1,600, 2,400 lpm depending on 80 lpm per sprinkler. If sprinkler system is designed as above provisions, the pressure and the flow rate accordingly become smaller than the minimum criteria about 50 % sprinklers. It results in serious consequence that the purpose of sprinkler system as initial fire reaction equipment is failure. In order to solve these problems, It is desirable that Performance-based fire protection design, hydraulic calculation, is carried out to all sprinkler system.

Design by means of the pipe schedule sprinkler system of NFSC 103 results in insufficient pressure and flow rate about 50% sprinklers of operating area. In order to solve the lack of pressure and flow rate, This paper compare and analyzed NFSC 103, National Fire Safety Code of Sprinkler System, with NFPA 13, Standard for the Installation of Sprinkler Systems, and suggested an alternative proposal. Changing the flow rate of each sprinkler from existing 80 L/min to 120 L/min, All of the operating sprinklers are fulfilled the minimum demands on 80 L/min and 1 bar. It is easy for everyone to design of the pipe schedule sprinkler system and it is optimum method that all sprinklers in design area are satisfied with minimum criteria.

Purpose: The purpose of this study is to present the commodity classification method of domestic rack-type warehouse for sprinkler system design. Method: On-site surveys and classification criteria of the NFPA, FMDS, EN and Japan were analysed and ISO 12949 test were carried out with proposed each classification commodity. Result: Based on a heat of combustion, a classification method for extra high, high, medium and low are proposed. Conclusion: Sprinkler design criteria to secure the maximum extinguishing strength for each class of commodity need to be applied.

Recently, evacuation safety of a resident of building become the major concern, because building has been higher and more complicated. Buildings in Korea should install the natural smoke venting or mechanical smoke exhaust equipment according to the building law. The smoke control is the most important to guarantee the evacuation safety. This study evaluate the influence to the height and temperature of smoke layer by enlarging smoke vent size and operating sprinkler system using CFAST (Version 6). Smoke venting size is larger, the effect to height and temperature of smoke layer is increased in below 5 MW fire. But, the correlation of these is decreased in above 10 MW fire. The case that opened smoke vent and sprinklered are applied, life safety criteria are satisfied regardless of fire size. After design the fire scenario according to the service and size of building. Install the smoke vent suitable for the fire size and verify that by experiment or simulation.
