  • Automatic Extinguishing Systems

Automatic fire suppression systems control and extinguish fires without human intervention. Examples of automatic systems include fire sprinkler system, gaseous fire suppression, and condensed aerosol fire suppression.

Fire Sprinkler Systems

Fire sprinkler systems work by spreading water over a fire from above at the onset of a fire. The system includes a water supply system that is connected by pipes that are fitted with fire sprinklers. The water comes out in a fine spray over the fire.

Fire Hydrant Systems

Fire Hydrant Systems A Fire Hydrant System is a critical active fire protection infrastructure designed to provide firefighters with a continuous, high-capacity, and high-pressure supply of water to extinguish medium-to-large-scale building fires.

Fire Hydrant Pumps

A Fire Hydrant Pump (or Fire Pump set) is an essential mechanical component of a building's water-based fire protection network. Its primary function is to boost hydraulic pressure from a water source—such as underground storage tanks and reservoirs ensuring water reaches all fire hydrants.

Clean Agent Fire Suppression Systems

Gaseous Fire Suppression

Also called clean agent fire suppression, is a term that describes the use of inert gases and chemical agents to extinguish a fire.

There are three common clean agent fire suppression systems to choose from, including: FM–200, 3M™ Novec™ 1230, and Inergen Clean Agent Fire Suppression System,

All systems use gases that are safe for the environment and humans, but they utilize different ways of suppressing a fire.

a. The FM–200 system is stored as a liquid and vaporizes when discharged. The system displaces the oxygen around a fire, but heat absorption is its primary extinguishing capability.

b. The Inergen system uses inert gases– nitrogen, argon, and carbon dioxide– to reduce the oxygen level and suppress the fire. While carbon dioxide is included, the concentration is safe for humans and the environment. Once the Inergen concentration is discharged, it returns to the atmosphere in its natural state.

c. The 3M™ Novec™ 1230 system uses a liquid that is vaporized when discharged, similar to the FM–200 system. However, unlike the FM–200 which suppresses the fire by heat absorption or cooling, the 3M™ Novec™ 1230 displaces the oxygen around a fire to suppress it.

Parts of a Fire Suppression System

A clean agent fire suppression system is commonly made up of three parts: smoke detectors, the control panel, and notification devices. The smoke detectors work as usual and will detect a fire before it has time to escalate into an uncontrollable event.

The smoke detector will send a signal to the control panel, which then alerts the notification devices and activates the release device to suppress the fire. The notification devices are there to warn occupants of the fire, and alert people in the area when the clean agent is about to be released.
