BD Alaris™ MRI Capsule
Features of the MRI Capsule
System Notifications
The MRI Capsule is equipped with both audio and visual notifications to promote user awareness . System Notifications
have been segregated into three different categories: Status Notifications, System Fault Indications and Pump Alarms,
based on their required response and method of user awareness . All System Notifications generated by the MRI Capsule
are considered Information Signals . They are not used to indicate an Alarm State but maybe used to replicate an
Alarm Signal present on the attached Pumps . The Primary and Secondary Speakers are used to generate the auditory
notifications . The purpose of the Primary speaker is to relay the MRI Capsule status . Whereas the Secondary speaker
indicates a failure within the system . The table below summarizes the behaviour of the auditory speakers .

In some user environments the Sound Pressure Level of the Primary and Secondary Speakers could be less
than the ambient noise.
A high level summary of the System notifications can be found in the table below . Status Notifications are represented by
small LEDs and are the only System Notifications that use the primary speaker . System Fault Indications are represented
by the System Fault Indicator and use the secondary speaker . The Pump Alarm Location Beacon is used to replicate the
Pump Alarm Condition .

It is recommended that all Pumps in a single care area be configured with the same alarm tones, where
applicable, to avoid User confusion. The Hospital/Facility is responsible for selecting and configuring the
desired alarm scheme.
Refer to each individual Pump’s Directions for Use for further details on the alarm schemes. The User
should always refer to the alarm on the Pump for the correct priority.
