Alarm receiver syntax:
Element Description
DeviceName Device name. In plain text so that the user can understand it.
Example: CC 01
DeviceIdentifier Device Identifier. Alternative syntax for the alarm receiver of a third-party manufacturer. If
the alarm receiver has a special address range or if DeviceName does not work.
Example: [13456]
RemoteAreaSiteName Remote area site name. In plain text so that the user can understand it.
Example: Chur
NetworkNumber Network number. Required with a third-party half router.

9.7 Alarm routing over the network
Alarm server and alarm clients
Alarm servers are entities capable of producing an alarm. Alarm clients are entities capable of receiving an
alarm.
There are two types of alarm client: temporary alarm receivers and pre-configured alarm receivers. The
following concept for temporary alarm recipients is only valid for Desigo PX.
Temporary alarm receivers
Temporary alarm receivers are not defined at the engineering stage. They can be connected to or removed
from the network at any time during operation. If a temporary alarm receiver is connected to the network, it
will perform the following activities for every alarm server:
The alarm recipient enters its address in the BACnet property recipient list [RecpList] of the BACnet
device object of the automation station, using the BACnet service AddListElement.
Read information about all currently existing alarms, and all currently outstanding acknowledgements,
from the automation station (BACnet service GetEventInformation). This ensures that the alarm
receiver – irrespective of when it was connected – displays the current alarm status of the system.
After making these entries, the temporary alarm receiver, while connected, will receive all alarm messages
from the automation station in accordance with the routing mechanisms described below.
If an automation station cannot transfer an alarm message to a temporary alarm receiver (e.g., because it is
no longer connected to the network), the address of the receiver concerned will be removed from the
[RecpList]. All alarm messages destined for that receiver will then be deleted.
