When testing a dry sprinkler system, a technician will simulate sprinkler head activation by opening an inspector’s test located at the farthest point of the system.

The fire alarm panel is checked to confirm alarm and supervisory signals were received. Sprinkler heads and piping are visually inspected condition, correct orientation, type and installation. While testing a wet sprinkler system the control valve is closed causing a supervisory signal which is confirmed by a technician at the fire panel. Once received the test valve is returned to normal and the test drain is opened to flow water simulating the activation of a sprinkler head. The technician observes the flow pressure and times the simulation until the alarm signal is received at the fire panel. Operation and timing is recorded on the inspection report. Although wet and dry sprinklers are the most common there are several other specialized systems to protect property and equipment.

Fire is one of the greatest discoveries of mankind. But when it goes out of control, it could eventually cause fatalities. As long as there have been buildings, there are fire accidents. Hence, the invention of fire sprinklers helped in restricting fire accidents and control damages. The first automatic fire sprinkler was invented by Henry S. Parmalee of New Haven, Connecticut in 1874. Until 1940s, fire sprinklers were installed only in commercial building to save properties. But over the years, fire sprinklers have become mandatory safety equipment in most of the schools, colleges, hospitals and multi storey buildings. A.S.Menon, Managing director, NFA, submitted a Research journal in 1993 at the British Automatic Fire Sprinkler Association meet. The journal stated that “if a building is Completely Sprinklered Building then 99.99% of the fire can be controlled by sprinklers alone”. Fire sprinkler systems are heat activated, one sprinkler head at a time. The sprinkler heads must detect a high enough temperature -- usually between 135 and 165 degrees Fahrenheit (57 to 74 Celsius) to get activated. Most sprinkler heads are equipped with a glass trigger filled with a glycerin-based liquid that expands at the appropriate temperature, breaking the glass and activating the sprinkler head. The sprinkler head is attached to a system of pipes that are hidden behind the walls or ceiling. These pipes wind through the building and outside to connect with a reliable water source. When the sprinkler head is triggered, a valve to the pipe system is opened, releasing the water that is kept under pressure from the pipes. The water is quickly pushed out of the pipes through the sprinkler head, spraying water downward and out to the sides. This carefully designed spray of water extinguishes the fire below and prevents it from spreading. Most sprinkler systems installed today are designed using an area and density approach. The design area is a theoretical area of the building representing the worst case area where a fire could burn. The design density is a measurement of how much water per square foot of floor area should be applied to the design area. These calculations are accurately calibrated by NFA’s Hydraulic SprinkCAD software. NFA Sprink CAD is built to design as per the NFPA standards. Fire sprinklers use about six times less water than a fire hose, they're actually less harmful to your property than a visit from the fire department. All the fire sprinklers do not activate at once like it’s shown in movies. Instead, they safeguard properties and lives! National Fire Armour (NFA India) is a leading organization deals in fire safety and fire protection systems like fire extinguishers, CCTV, fire hydrant system, fire alarm systems, fire safety and fire fighting systems in India.
