HOLISTIC FIRE PROTECTION SOLUTIONS FOR DATA CENTERS
Early Fire Detection with TITANUS® Aspirating Smoke Detectors
The patented and certified air sampling smoke detectors in the TITANUS® family provide maximum sensitivity; with TITANUS RACK·SENS®, WAGNER has developed a customizable detector that integrates easily into servers or server cabinets. These reliable, sensitive air sampling smoke detectors are designed to protect rooms and equipment, and provide preventative protection in cable ducts. They can detect even the smallest quantities of smoke particles as early as possible, providing a head start that allows users to react quickly and keep damage to a minimum.
Thanks to LOGIC·SENS technology, they can detect incipient fires even before they are visible, while remaining secure against false alarms.
Residue-free Extinguishing in Data Centers with the FirExting® Gas Extinguishing System
Should the fire alarm system notify the fire detection control panel that a fire has occurred, gaseous extinguishing agents have proven a highly effective method of suppressing data center and server-room fires. WAGNER relies upon CO2 as an extinguishing agent in some circumstances, and on request it may also employ Novec 1230 — but nitrogen is its preferred agent of choice.
As soon as the extinguishing systems direct the inert gas nitrogen into the protection area, the nitrogen displaces the oxygen content in the air and puts the fire out. This gas is what makes WAGNER’s FirExting® fire extinguishing system an effective, residue-free method of fire suppression. Nitrogen is non-toxic, and as a natural component of the air we breathe (78% vol.), it has a similar density to air. In the event of a fire, the inert gas distributes quickly and homogeneously throughout the extinguishing area, and leaves no residue. Nitrogen supplies can also be stored easily in space-saving extinguishing cylinders.
Sound Absorption Keeps IT Safe from Vibrations: FirExting®SILENT
To avoid unwanted vibrations due to the rapid release of the gas, WAGNER fire protection uses specially developed sound absorbers which prevent vibrations when the extinguishing system is triggered – for the security of hard drives. This sound pressure protection mechanism is mounted onto the system’s extinguishing nozzles, and lowers sound pressure levels to around 98 dB(A). The FirExting®SILENT fire protection system has VdS approval.
Preventative Fire Protection in Data Centers with OxyReduct® Active Fire Prevention
After a fire has been extinguished, it can be useful to employ OxyReduct®active fire prevention to keep fires from re-igniting. This oxygen-reduction system ensures that the lower oxygen concentrations established after extinguishing can be maintained for a theoretically unlimited amount of time, preventing the blaze from starting again and thus eliminating the need to cut power.
WAGNER’s OxyReduct® fire protection system generates nitrogen from the air in the room, and the ventilation system feeds it into the protected area, where it continuously reduces the proportion of oxygen in the vault to a heavily fire-retardant atmosphere. O2 concentrations of 15.9 % vol. are below the ignition thresholds of typical IT materials, so fires can no longer develop or spread.
