This European Standard specifies the characteristics of electrically- generated signals intended
for use with medical devices, either individually or as part of a centralized system. This
European Standard applies only if a particular device standard makes reference to it. It is
expected that requirements for the application of the signals specified in this standard will
be included in Particular Standards for particular medical devices.
This European Standard does not specify:
a) the medical devices On which alarms are to be provided;
b) the conditions that actuate the alarms;
C) the means of generating the signals;
d) the characteristics of secondary alam systems, i.e. alarm systems that are
activated in case of a failure of the prirnary alarm system;
e) the allocation of priorities to alarms.
