NurseCall N46 Wall Transmitter
5.2.3
Connecting to the power supply
The NurseCall N46 Wall Transmitter can be powered by a lithium battery or/and an external
12-24 VDC power supply. If the device is powered with an external power supply, the battery
is not necessary, but it can be used as a backup power supply in case of power loss.
If the device is powered by the battery only, the battery life is about 2 years. However, it is
recommended to change the battery once a year.
If the device is powered by an external power supply and the battery is used as backup power
supply, it is recommended to check it at regular intervals (for instance once a year) and to
change it if necessary.
CAUTION!
!
When powering the device, the external 12-24 VDC power supply must be equipped with a
setting off safety device, that is easy to access. The power supply must also be equipped with
a safety fuse of lower value, e.g. 100 or 125 mA.
5.2.4
Reset
All parameters are reset when powering up the device (battery or external power supply). This
operation causes the synchronization of the daily message.
In order to perform a reset, make sure to remove both the battery and the external power sup-
ply, make a short-circuit on the two pins marked Reset on the next figure before powering the
device up again.
NOTICE!
i
All connections as well as the configuration need to be carried out before powering the device
(insertion of the battery and/or application of the external power supply).
5.2.5
Transmitter Identification
All NurseCall N46 Wall Transmitters are provided with their own radio identification code that
is assigned in the factory. During the installation, it is necessary to set the relationship
between the identification code of the Transmitter and the place where it is installed (floor/
room/bed or single number). This identification is programmed on the Nursecall Main Unit
(refer to the NurseCall Main Unit User Manual).
5.2.6
Operation Check
Once the transmitter has been installed and setup properly, it is recommended to check all
functionalities of the device. The radio transmission can be checked by sending an acknowl-
edgement call by pressing the green button.
