Fire system reduces risk to hard drives

To minimise the risk of high noise levels from automatic extinguishing systems that use an inert gas damaging hard disk drives, Siemens Building Technologies Division has developed a discharge nozzle that reduces noise levels by around 20 dB(A). Extensive research by Siemens showed that high levels of a particular frequency from an extinguishing system discharge could seriously damage hard drives, and developed the Sinorix silent discharge nozzle to eliminate this risk.

These nozzles can be integrated into an existing system, enabling an installation to be updated rather than replaced completely.
