10.11 Nurse Call
The ventilator provides nurse call function that enables the ventilator to output nurse call
signals to the nurse call system when an alarm meeting the user set requirements occurs.
The nurse call function is activated only when:
1. The nurse call function is switched on;
2. An alarm which meets the user set requirements occurs;
3. The ventilator is not in AUDIO PAUSED status.
Follow these steps to set nurse call:
1. Push the [Setup] key. Select [Maintain] and select [User]. Enter the required password.
Then select [Interface Setting] and select [Nurse Call].
2. Select [Switch] and toggle between [ON] and [OFF].
[ON]: to switch on the nurse call function.
[OFF]: to switch off the nurse call function.
3. Select [Signal Type] and toggle between [Pulse] and [Continuous].
[Pulse]: indicates that the nurse call signals outputted are pulse signals lasting for
one second. When multiple alarms occur simultaneously, only one pulse signal is
outputted. If a new alarm occurs when the ongoing alarm is not cleared yet, a new
pulse signal will be outputted.
[Continuous]: indicates that the nurse call signal lasts until the alarm ends, i.e. the
duration of a nurse call signal equals to that of the alarm.
4. Select [Contact Type] and toggle between [Normally Open] and [Normally Closed].
[Normally Open]: for systems that require normally open signal.
[Normally Closed]: for systems that require normally closed signal.
5. Select [Alarm Level] and select levels of alarm that will trigger nurse call signal.
6. Select [Alarm Type] and select types of alarm that will trigger nurse call signal.
If no setting is made for [Alarm Level] or [Alarm Type], nurse call signals will not be
triggered no matter what alarm occurs.
