Disclaimer
It is the responsibility of the installer to ensure that the user is aware of the relevant contents of this
document and the documents listed herein. To ensure full system capabilities it is important to
check the following elements before installing the EXXFIRE systems:
1. Air tightness /leakage of the protected volume (e.g. cabinet). Gaseous fire protection works
only if the extinguishing gas can be kept inside the protected volume as long as possible to
prevent reignition
2. If in doubt the following precautions can be made; Close off all openings visible (cable
entries, ventilation etc.) with fire retardant material
3. Perform a functional test with an actual extinguishing to do an oxygen level measurement
for each cabinet type to ensure the proper design concentrations and hold time per
installation
4. If hold time is too low use EXXFIRE relay contact to switch OFF the Power to the cabinet, this
will prevent reignition also.
