Wet fire systems are the most common of fire sprinkler systems. A wet fire system consists of sprinklers connected to a pressurised piping system filled with water. In the presence of heat and fire the sprinkler bulbs will break, releasing water to supress the fire in a bid to limit harm to people and property. Wet fire systems are often integrated with alarm systems to warn occupants and the fire brigade. Wet fire systems are generally implemented in car parks, residential, commercial and warehouse building.
