9 Alarms and safety features
9.1 Introduction
The Ambix nova pump has a continuous inspection system that operates as soon as it is
in use, but it cannot replace the users present at the bedside.
It is recommended that the user should be in front of the Ambix nova pump, for best visibility
of alarm display.
Please make sure the appropriate reaction to alarm is undertaken. A wrong or delayed
reaction can lead to a delay of therapy.
WARNING
The pump emits audible alarm signals. Audible alarm signals from medical
devices may be masked by environmental noise. Ensure the alarm sound level
is audible to the user, taking into account the environment.
All alarms' sound levels are within the range of 45 dB(A) to 85 dB(A).
Three different alarm sound levels are available to choose: low, medium and high. To set
the alarm sound level, please go to
on page 57.
NOTE:
dB(A) is the level average pressure measured following ISO 3744.
