Two sensor circuits activate the system, one tracking early smoke or fumes internally, and the other sensing external air quality.
When contaminants (such as smoke or dust) are sensed externally, the system goes into full recirculation mode and shuts off all dampers admitting fresh air while commencing back-up server room cooling.
Once in full recirculation mode the data center operates in a closed circuit, preventing any external contaminant entering the IT rooms. If a fire in the server room is detected, the data center fire suppression system will be activated.
When in full recirculation mode the BladeRoom Data Center maintains N+1 resilience and full concurrent maintainability.
The system stays in recirculation mode until acceptable external conditions have returned.Top
Activation of the internal VESDA system will also put the BladeRoom into recirculation. This will dramatically reduce the amount of fresh air passing through the space, which makes it less likely that a smoldering item will develop into a fire.
In the event that a fire does develop, and both fire detection circuits (optical and ionization detectors) are activated, the fire suppression system will be discharged. Full cooling continues to be available after gas discharge.
The data center fire suppression system can be an inert gas (IG55) or a connection to a pre-action sprinkler system.
The VESDA and smoke detection and data center fire suppression systems fully integrate into the data center monitoring system, providing the flexibility to set alarm responses and configure alerts and notifications to suit your standard practice.Top
