PNG Mode: Monitoring in compliance with BGR 139
The alarm server acts as the control centre for this personal alarm system (PNA system). The
alarm server controls and monitors the PNG-S and responds to its messages and alarms. The
CLIP information from the setup message at connection setup is required for managing the
PNG-S.
The user performs a function test on the sensors prior to activation. Monitoring is activated by
the alarm server if the function test has been performed successfully.
Alarm calls from the PNG-S are directed to the configured alarm destination. To ensure that the
alarm calls reach the alarm destination, the calls are repeated until an alarm callback from the
alarm server has been detected or the configured number of retries has been reached.
Nevertheless, it cannot be fully guaranteed that an alarm call will reach the programmed alarm
destination. The alarm server therefore also checks the communication paths to the PNG-S
and polls the PNG-S cyclically. If there are no responses, the alarm server generates a
technical alarm and assistance is deployed. A local alarm is triggered additionally on the
PNG-S.
The handset and therefore the person who triggers the alarm can then be located using
positioning services. When the alarm has been processed, an alarm signal is emitted on the
PNG-S, which serves to further pinpoint the location of the party who triggered the alarm.
The alarm server is responsible for resetting the alarm and disabling monitoring. The alarm
server checks in the process whether monitoring can be disabled if necessary. For example the
disabling location is checked as a criterion.
2.4.1.1 In alarm status: Callback by HNA
The handset has sent an alarm signal to the PNEZ and is consequently in alarm status. The
HNA acknowledges the alarm call with an alarm callback. The handset answers this control call
automatically.
The alarm callback allows the events at the alarm location to be monitored at the HNA. The
speakerphone function can be used to communicate with the alerting party if necessary.
>
As an employee at the HNA, make sure to obtain permission to listen in from the
monitored person before monitoring.
If individual workplaces are prohibited in the applicable regulations, this ban may not
be circumvented with a personal alarm device.
