6.12 Nurse Call
The monitor also provides a multi-function connector to output nurse call signals when a
user-defined alarm occurs. To obtain a nurse call signal, use the nurse call cable (
P/N:
009-003116-00 ) we supply to connect the hospital nurse call system to the
multi-function connector of the monitor and then follow this procedure:
1. Select [ Main ]
→
[ Maintenance >> ]
→
[ User Settings >> ]
→
Enter required password
→
Select [ Ok ] and then access [ User Settings ] menu.
2. Select [ Nurse Call >> ] to access the [ Nurse Call >> ] menu.
3. Select [ Signal Type ] and toggle between [ Pulse ] and [ Continuous ].

[ Pulse ]: the nurse call signal is pulse signal and each pulse lasts 1 second. When
multiple alarms occur simultaneously, only one pulse signal is outputted. If an
alarm occurs but the previous one is not cleared yet, a new pulse signal will also
be outputted.

[ Continuous ]: the nurse call signal lasts until the alarm ends, i.e. the duration
of a nurse call signal equals to that of the alarm condition.
4. Select [ Contact Type ] and toggle between [ Normally Open ] and [ Normally
Closed ].

[ Normally Open ]: Select if your hospital’s nurse call relay contact is normally
open.

[ Normally Closed ]: Select if your hospital’s nurse call relay contact is normally
closed.
5. Select [ Alarm Level ] and set the alarm level for nurse call-triggering alarms.
6. Select [ Alarm Category ] and then select the category to which the nurse
call-triggering alarms belong.
Alarm conditions are indicated to nurses only when:
1. The nurse call system is enabled
2. An alarm that meets your preset requirements occurs, and
3. The monitor is not in the alarm paused or silence status.
If no setting is selected from [ Alarm Level ] or [ Alarm Category ], no nurse call signal will
be triggered whatever alarms occur.
WARNING

To obtain the nurse call signal, use the nurse call cable (PN: 009-003116-00) we
supply. Otherwise the nurse call function will not work and the monitor may be
damaged

Do not rely exclusively on the nurse call system for alarm notification.
Remember that the most reliable alarm notification combines audible and
visual alarm indications with the patient’s clinical condition.
