Localisation functions

Localisation functions
With the localisation functions, the personal emergency signal centre can determine
the location of the radio set. Prerequisite is that the radio set is equipped with a GPS
receiver, or that inductive localisation beacons (IOS) are permanently installed on the
premises where the personal emergency signal system is being operated. The radio
set saves GPS position data or the code of the inductive localisation beacon (IOS)
while it is within transmission range. The localisation functions can be used for the
following application scenarios:


Localisation of the radio set in case of alarm


Tracking of the radio set in an alarm situation (p. 120)

Warden control mode (p. 121)
Localisation of the radio set in case of alarm
After a personal alarm is triggered, the radio set transmits the codes of the last three
inductive localisation beacons (IOS) saved to the personal emergency signal centre.
The staff at the personal emergency signal centre can reconstruct the path you have
covered with the radio set immediately before the alarm was triggered by analysing
these codes.

Tracking of the radio set in an alarm situation

After a personal alarm is triggered, the radio set remains in in alarm condition until
the alarm is terminated, see section „Alarm and alarm processing" (p. 130).
If the radio set receives additional codes from inductive localisation beacons (IOS)
while in alarm condition, e.g. because you are fleeing from a danger while carrying
the radio set after triggering the personal alarm, the radio set will also transmit these
codes to the personal emergency signal centre. In this way, the staff at the personal
emergency signal centre can trace the escape route during the alarm condition.
