Fire Suppression Systems are commonly used on heavy power equipment. Suppression systems use a combination of dry chemicals and/or wet agents to suppress equipment fires. Suppression systems have become a necessity to several industries as they help control damage and loss to equipment. Common means of detection are through heat sensors, wiring, or manual detection (depending on system selection).
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers can be automatic or open orifice. Automatic fire sprinklers operate at a predetermined temperature, utilizing a fusible element, a portion of which melts, or a frangible glass bulb containing liquid which breaks, allowing the plug in the orifice to be pushed out of the orifice by the water pressure in the fire sprinkler piping, resulting in water flow from the orifice. The water stream impacts a deflector, which produces a specific spray pattern designed in support of the goals of the sprinkler type (i.e., control or suppression). Modern sprinkler heads are designed to direct spray downwards. Spray nozzles are available to provide spray in various directions and patterns. The majority of automatic fire sprinklers operate individually in a fire.
Gaseous fire suppression is a term to describe the use of inert gases and chemical agents to extinguish a fire. The system typically consists of the agent, agent storage containers, agent release valves, fire detectors, fire detection system (wiring control panel, actuation signalling), agent delivery piping, and agent dispersion nozzles. Less typically, the agent may be delivered by means of solid propellant gas generators that produce either inert or chemicallyactive gas.These Agents are governed by the NFPA Standard for Clean Agent Fire Extinguishing Systems When it comes to protecting the information and hardware in a datacenter.
Gaseous fire suppression systems have some obvious advantages. People choose gaseous systems is because they don’t want water all over their computer systems. The system typically consists of the agent, agent storage containers, agent release valves, fire detectors, fire detection system (wiring control panel, actuation signalling), agent delivery piping, and agent dispersion nozzles. Less typically, the agent may be delivered by means of solid propellant gas generators that produce either inert or chemically active gas.
Merits of gas based fire suppression system :

Fire Suppression System in Datacenter is considered with Simultaneous Flooding in the following areas:
- Room Void.
- Ceiling Void (Above False ceiling).
- Floor Void (Below False flooring, If available).
