Extended Coverage Sprinklers

Extended Coverage Sprinklers are intended for the protection of areas larger than those specified in standard installation rules and for specific light, ordinary, or extra hazard occupancies. Sprinklers are designed to protect ordinary hazard occupancies with a maximum coverage area.the standard distribution of sprinkler heads will not provide enough coverage. In these cases, extended coverage sprinkler heads can be installed to increase the spacing between heads. Extended coverage sprinklers have a water distribution radius of a little over 10 feet, so they can be spaced approximately 20 feet apart.                                                                   

Criteria for the location of sprinkler heads. First, sprinklers must be located so they are within the hot-gas layer that develops near the ceiling during a fire because activation occurs when the sprinkler head reaches a certain temperature. Second, they must be located so that the water that is discharged from the sprinkler is not disrupted or affected by construction elements such as beams, trusses, or soffits.The extralarge orifice produces the flows required to meet Light and Ordinary Hazard density requirements at lower pressures than standard orifice or large orifice sprinklers.The glass bulb operating element and special deflector characteristics meet the challenges of quick response extended coverage standards.During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern.

                                                             

Two Main Criteria For Location Of Sprinkler Heads

• Because fire sprinklers are heat activated, sprinkler heads must be located high up on or near the ceiling.
• Sprinkler heads must be unobstructed to provide maximum flow to the areas that need it. This means they cannot be blocked by beams, trusses, soffits, or any other elements of your building’s construction.                   

Digital Intelligent System

An Digital Intelligent Systems is a machine with an embedded, Internet-connected computer that has the capacity to gather and analyze data and communicate with other systems.  As this ongoing trend continues, many foresee a scenario known as the Internet of Things (IoT), in which objects, animals and people can all be provided with unique identifiers and the ability to automatically transfer data over a network without requiring human-to-human or human-to-computer interaction. digital Intelligent systems that can analyze digital information and sensory data, draw the right conclusions, and act on them in the digital or physical world are of rapidly growing importance.intelligent fire alarm system shall comply with requirements of  Standard for protected premises signaling systems. The system shall be electrically supervised and monitor the integrity of all conductors.Fire Finder system operates with high-performance devices and systems.

Deluge Fixed Fire Protection System

Deluge system is designed to protect high hazard areas containing a severe fuel hazard with a high heat release rate by bringing a large number of open sprayers into action simultaneously in the event of a fire. Deluge valve system comprises of a control valve, a sprinkler operated detection system and a dedicated water supply system. For small or confined high hazard risk areas, Multiple Controls can be used instead of sprinklers. Deluge system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system. Deluge systems are used in the protection of large Aircraft Hangers as one primary means of fire protection.                                                    

Deluge fire sprinkler systems are used where special hazards create a concern for rapid fire spread. These systems provide a simultaneous application of water over the entire hazard to ensure fast and effective suppression of the fire. Water is not present in the piping until the deluge valve is tripped, reducing the risk of leakage or damage to unseen areas of the building. deluge fire sprinkler  system is to quickly wet down an entire hazard area to prevent a fire from spreading. They are usually used in facilities that contain hazardous materials such as: flammable liquids, chemicals, and explosives.Deluge pipe fire sprinkler systems feature open-type sprinkler heads attached to a dry pipe that is connected to a main water supply. Using an innovative detection system that recognizes smoke or heat, this fire suppression installation activates a valve that releases water to all sprinklers.
