2.2.4 RS-485 interface
One NurseCall Main Unit and up to 32 NurseCall Relay Units can be connected by a RS-485
bus. The bus must be connected to pins 2 and 5 of the RS-485 socket.
For connector wiring, see Section A.5.4 RS-485 socket (unit rear), page 34.
NOTICE!
Keep polarity equal when connecting further units to the RS485 bus!
NOTICE!
Maximum RS485-bus length: 1200 m.
Use only one twisted pair cable for the interconnection.
NOTICE!
The receiver units located at the two ends of the bus must be terminated with a 100 Ohm
resistor. See Section 3.2.7 Connecting the RS-485, page 17 for more information about the
jumper setting.
In this configuration, you always should connect the NurseCall Main Unit first. The NurseCall
Relay Units must then be connected to the RS485-bus one by one, not at the same time.
Relay output
In the same connector, a potential free contact is available. It is a low current switching
contact. The relay (potential free, switching power max. 48 V / 0.5 A) is activated at a call for
help, call for assistance or fire alarm. This relay can be set as closing or switching contact
(cycle of 10 seconds on / 10 seconds off). This feature can be used to drive a signal lamp for
example.
For connector wiring, see Section A.5.4 RS-485 socket (unit rear), page 34.
For relay setting, see the user manual of the NurseCall Main Unit.
2.2.5 Antenna
The antenna is connected to the NurseCall Relay Unit using the adapter supplied with the
unit.
See Section 3.2.4 Installing the antenna, page 14.

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.
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.
The event buffer will normally be filled with the last 18 or 100 entries.
In the alarm buffer, only the active alarms are present.

5.2.1 Switching between alarm and event buffers indication
The alarm buffer is indicated by default. If you are in the event buffer, the unit changes
automatically to the alarm buffer after 1 minute without activity.
If there are no entries in the alarm buffer, the display shows the actual date and time.
To switch from alarm to event buffer and vice versa, press .
Scroll the alarms or the events with and .
Scroll the alarms only with the Green button.
5.2.2 Display indications
With the Yellow button, you can switch between three available information blocks.
The following information is displayed when an alarm or a message arrives:
First information block
– In case of a "floor/room/bed" display mode:
1. criterion of the alarm or message
2. alarm (A) or event (E) followed by its order in the buffer
3. identification of the transmitter location (floor/room/bed numbers)
– In case of "single number" display mode:
1. criterion of the alarm or message
2. alarm (A) or event (E) followed by its order in the buffer
3. identification of the transmitter location (three digits or four signs)
Second information block
4. date of the event;
5. time of the event;
6. main unit (space) or relay Unit (A...f) identification number;
7. quality of the received radio signal.
This information is visible in all display modes.

Third information block
8. position of the last passed beacon, visible in all display modes. If no beacon is registered
or if the alarm is sent outside of the range of a beacon, the POS 000 will be displayed.
In the alarm buffer, the total number of entries is indicated on top at the right. You can
immediately see how many alarms are active. In this example, there are a total of three alarms
in the alarm buffer. In the event buffer, the position of the event in the buffer is indicated:
LOCAL ACK. E01
06:05:11 13:33:05 C2
Here, E01 corresponds to the latest entry in the event buffer.

5.2.3 The green button does not work
Problem: you have tried unsuccessfully to acknowledge an alarm with the Green button.
Cause: the local acknowledgement is disabled.
Solution: activate the local acknowledgement function.
See the NurseCall Main Unit user manual.
5.2.4 Disconnecting a Relay Unit
If a Relay Unit stops communicating with the Main Unit, an alarm "Relay Off" is generated on
the Main Unit. This alarm can only be acknowledged on the Main Unit by pressing the Green
button, followed by the code 45. Thereafter, an event "No Relay" is generated.
As soon as the Relay Unit communicates again with the Main Unit, the Event "Relay On" is
generated. This operation is independent of the local acknowledgement setting.

6.1 Checking the system
Check the correct function of your NurseCall system.
Perform periodically an alarm test.
6.2 Monitoring the power supply
In case of a power failure, the NurseCall Relay Unit emits a beep and the following message is
displayed alternatively with the date and time display:
Main Power
Error
The backup battery ensures that the NurseCall Relay Unit remains operational even in the case
of a power failure. When fully charged, the battery ensures a power backup of 24 hours.
When power returns after a power failure, the battery is recharged. If it has been completely
discharged, it will reach its full capacity after 24 hours of charging time.
6.3 Monitoring the backup battery
The status of the battery is indicated on the top right of the display.
To check the backup battery voltage, press . The following message is displayed:
