Sprinkler Ordering and Usage Guidelines

HD Fire Protect is a leading manufacturer and supplier of wide range of sprinklers. Our products are UL Listed and/or FM approved to ensure high quality assurance along with the best performance in its segment.
A fire sprinkler is chosen by evaluating various factors like the occupancy hazards, applications, and conditions of the building, more specifically, the area that is to be protected.
Sprinkler Systems need to be designed as per NFPA 13 - Standard for the Installation of Sprinkler Systems.
Hazard Occupancies: Sprinklers chosen largely depend on Types of Occupancies. Occupancy classifications are given in NFPA 13. Standard Sprinklers are commonly used in Light and Ordinary Hazard Occupancies. These are the occupancies where quantity and/or combustibility of contents is low and fires with relatively low to moderate rates of heat release are expected. In Ordinary Hazard Group 1, stockpiles of combustibles do not exceed 8 feet and fires with moderate heat release are expected while in Ordinary Hazard Group 2, stockpiles of combustibles do not exceed 12 feet and stock piles of contents with high heat release do not exceed 8 feet. Maximum floor area on any one floor to be protected by sprinklers supplied by one sprinkler system riser or combined riser is 52,000 Sq. feet for Light and Ordinary Hazard Areas.
Other Occupancies like Extra Hazard need special sprinklers with more water than Light and Ordinary Hazard Areas.

Now, there are two types of responses, Standard Response and Quick response. Refer to the Table below to know what type of sprinkler response is required for your use.
Standard Response Quick Response
They have a Bulb Diameter of 5 mm They have a Bulb Diameter of 3 mm
They act with standard thermal sensitivity They act slightly faster
They act on active fire and soak or pre-wet surrounding areas for preventing spreading of fire Apart from preventing the spreading, they spray water higher, towards the walls and ceiling so that the fire doesn’t reach high
Usage: buildings, warehouses and commercial offices, etc. Usage: schools, healthcare buildings, offices, light hazard areas, etc.
However, choosing one sprinkler type over another is not simple. There are numerous factors as well as fire codes, k-factors and other regulations that will determine which type is best for your building. Both types of fire sprinklers have lifesaving capabilities and both have their own strengths.
