1.9 Alarm Activation
If an FC4 U sensor detects an alarm situation or if the user triggers an alarm manu-
ally, the handset transmits an appropriate alarm telegram. The telegram includes the
most recently received ILB code (site of the alarm) and the type of alarm. The base
station or the repeater in whose reception area the alarm has been activated relays
the alarm to the UDSS server. Alarm activation takes place by means of a dial-up
connection between the handset and the UDSS server.
The UDSS server evaluates the alarm telegram. The ILB code is converted into
appropriately configured text information. The received alarm is displayed in graphic
and/or text form at the alarm management point of the UDSS server. A server
acknowledgement is sent to the handset initiating the alarm. All in-coming alarms
reports are saved as a data set in a database transaction table. At any stage, a
history of alarm reports can be requested from the alarm management point of the
UDSS server for subsequent evaluation.
If the control point is not manned continuously, then all alarms can also be relayed
via messaging to other devices in the field. In this case, the location report is
displayed as text.
Depending on the configuration, an alarm can also be relayed to external devices
(not connected to the DECT system): for example, to mobile radios or landline tele-
phones or in the form of e-mail.
