This part of ISO 9703 specifies the characteristics of the auditory component of electrically generated primary alarm systems in anesthesia and respiratory care, either individually or as part of a centralized system. It applies only if a particular International Standard for a medical device makes reference to it.
This part of ISO 9703 does not specify
(a) the medical devices on which these alarms are to be provided;
(b) the conditions that actuate the alarms;
(c) the means of generating the alarm signals;
(d) secondary alarm system characteristics, i.e. alarm systems which are activated in case of a failure in the primary alarm system;
(e) the allocation of priorities to alarms.
NOTE 2 It is expected that requirements for the application of the auditory alarm signals specified in this part of ISO 9703 will be included in Particular Standards (as formulated in IEC) for the particular medical devices.
