alarms are switched off.
9.9 Latching Alarms
The latching setting for physiological alarms defines how alarm indicators behave if you do not reset the alarms.
■ If you do not “latch” physiological alarms, their alarm indications disappear when the alarm condition ends.
■ If you “latch” physiological alarms, all visual and audible alarm indications remains until you reset the
alarms. For latched alarms the time when the alarm is last triggered is displayed behind the alarm message.
You can separately latch visual indications or simultaneously latch the visual and the audible indications.
■ When visual indications are latched, visual indications, including alarm lamp, alarm message and its
background remains when the alarm condition ends and the time when the alarm last triggered is
displayed behind the alarm message.
■ When audible indications are latched, the monitor issues alarm sounds when the alarm condition ends.
To latch physiological alarms, follow this procedure:
1. Select the Main Menu quick key → turn to the third page → from the System column select Maintenance
→ input the required password → select Ok.
2. Select the Alarm tab → Latching tab.
3. Select how you want to latch the alarms.
Alarm latching rules are as follows:
■ You can separately latch visual alarm signal.
■ Latching audible alarm signal simultaneously latches visual signal.
■ Selecting alarms of lower priority simultaneously latches higher priority alarms.
• Changing alarm priority may affect the latching status of corresponding alarm. Determine if you
need to reset the alarm latching status if you changed the alarm priority.
• When the alarm system is reset, latched physiological alarms are cleared.
9.10 Nurse Call
The monitor provides a nurse call connector to output nurse call signal when a user-defined alarm occurs. To
obtain nurse call signal, use the nurse call cable (PN: 009-005391-00) to connect the hospital nurse call system
with the monitor’s nurse call connector.
Alarms are indicated on the nurse call device only when the following conditions are met:
■ The nurse call system is enabled.
■ A user-defined alarm occurs.
■ Alarms are not paused or reset.
