Fire Suppression Systems

The fire suppression network is a system that rarely activates but must function fully when it does. Therefore, the main question during selection is not "which sprinkler" but what type of network it will be: wet, dry, pre-action, or deluge.

Types of Alarm Valves

• Wet Alarm Valve — pipes are constantly filled with water; the simplest solution for enclosed spaces with no risk of freezing.
• Dry Alarm Valve — pipes are filled with compressed air, water only enters after the sprinkler is activated; suitable for cold storage, attics, and open areas.
• Pre-action — requires both a detector signal and the activation of sprinklers for water supply; used in places where accidental water flow is unacceptable.
• Deluge — all nozzles are open, water is supplied to the entire area as soon as the signal is received; for high-risk zones.

Network Elements

The type of sprinkler is selected based on the ceiling and the function of the space: upright for open pipe networks, sidewall for wall applications, and concealed type for spaces with suspended ceilings and where appearance is important. Pipe connections are made with a threaded system — couplings, mechanical tees, elbows, reducers, and caps reduce welding work, facilitating future expansion of the network. The monitored butterfly valve reports the open status of the valve to the control panel.
