(e. g. signal horns) may cause hearing damage.
• Leave the extinguishing zone without delay and within the pre-discharge timer when an
alarm is given.
• Stay out from the immediate vicinity of acoustic alarm equipment and discharge nozzles.
NOTICE Property damage from cooling ambient air.
The discharged extinguishing agent extracts heat from the ambient air contained in the
extinguishing zone. This causes the air in the immediate discharge zone of the extinguish-
ing nozzles to cool to below -58 °F (-50 °C).
• Do not attach/store components that are sensitive to cold in the immediate vicinity of the dis-
charge nozzles.
NOTICE Property damage from excess pressure.
Due to the emitted extinguishing agent, an overpressure arises in the extinguishing zone
which can lead to damages to walls and doors of the protected enclosure.
• Ensure that pressure relief devices are installed in the protected enclosure and included in the
design of the system.
• Make sure that the function of the pressure relief is checked regularly.
WARNING Inadequately qualified persons pose a hazard.
