Function
The OxyReduct® fire prevention system reduces the
oxygen content in the protected area to a constant
17.0 vol% and maintains it at this level.
If the TITANUS® air sampling smoke detection system
detects signs of fire, the control panel is notified and
nitrogen cylinders are used to initiate quick release to
an oxygen level of 7.0 vol%.
