Data Centers

Pre-action systems, sensitive equipment protection

The main risk of water extinguishing in a data center is not just the fire itself but also accidental water flow: the activation of a sprinkler due to mechanical damage can render operational equipment inoperable. Therefore, server and UPS rooms are usually kept dry (empty) in the network.

Pre-action Principle

In a pre-action system, the pipes are filled with compressed air, and water is only released when TWO conditions are met simultaneously: the detector confirms the fire, and the sprinkler opens due to heat. Thus, mechanical damage (for example, a strike to the sprinkler) does not cause water flow — the system interprets this as a loss of air pressure and alerts.

Considerations in the Project
  • Constant monitoring of air pressure and the size of the compressor — it must be suitable for the network volume.
  • Monitored valves: the status of all open-close valves should be visible on the control panel.
  • Sprinkler placement should be coordinated with cooling aisles (hot/cold aisle) and cable trays.
  • Concealed type sprinklers are used in technical rooms with white ceilings without compromising aesthetics.
