5 Operation

5.1 Adjusting the loudspeaker volume

When the NurseCall Relay Unit is in standby mode:
Press to increase the volume.
Press to decrease the volume.

5.2 Consulting the alarm or event buffer

The NurseCall Relay Unit uses an alarm buffer and an event buffer for display indication.
The following alarms and messages are stored into the alarm buffer:
– call for help
– call for assistance
– reserve call (call for help 2)
– technical call
– fire alarm
– battery low message
– error message
– disconnection of a NurseCall Relay Unit from the RS-485 bus
If alarms are repeated, only the least recent entry remains in the buffer. The call for assistance
replaces the call for help, the reserve call and the technical call in the alarm buffer.
In addition to all the alarms, all possible entries are stored in the event buffer.
The following messages are directly stored into the event buffer:
– acknowledgement N46, sent by an N46 Wall Transmitter, S35 or S37 Transmitters
– acknowledgement by S35 or S37 Transmitters
– local acknowledgement, an acknowledgement at the NurseCall Main Unit or Relay Unit
– daily message check
– personnel arrival message (A, B, C and D)
– personnel departure message
– power outage of a receiver unit
– return of power at a receiver unit
– backup battery low of a receiver unit
– interruption of the RS-232 connection interface between the NurseCall system and a PC
– return of the RS-232 connection interface between the NurseCall system and a PC
– connection of a NurseCall Relay Unit to the RS-485 bus
– transmission of the event "door" by a RAC Wireless Contact.
The event buffer will normally be filled with the last 18 or 100 entries.
In the alarm buffer, only the active alarms are present.
NOTICE!
The alarm and event buffers have a capacity of 18 or 100 entries. See the maximum number of
events buffered, in the NurseCall Main Unit user manual.
