Personal Emergency Signal (PES) Functions
Will-independent emergency signal functions

Time sequence
Any will-independent alarm results in the transmission of the alarm to the personal
emergency signal centre as soon as the alarm condition occurs and the programmed
delay and pre-alarm time have expired. You can stop the transmission of the alarm if
you eliminate the alarm condition during the delay and pre-alarm time, or if you end
the pre-alarm during the pre-alarm time.

Description
1
Alarm condition occurs The radio set identifies an automatic (will-independ-
ent) alarm condition.
2
Start of pre-alarm on
the radio set
The alarm condition detected at time (
1
) still exists.
The radio set starts signalling the pre-alarm.
3
Ending of the pre-
alarm by the operator
If you acknowledge the pre-alarm during the pre-
alarm period or if you set aside the alarm condition,
the pre-alarm signal will fall silent. The alarm is not
triggered for the time being.
The only point in time at which a pre-alarm can be
ended is during the pre-alarm time (
c
).
4
Transmission of
the alarm
The radio set transmits an alarm to the personal
emergency signal centre. In addition, the radio set
starts signalling the alarm (
d
). This lasts until the
alarm is reset.
5
Arrival of alarm at the
personal emergency
signal centre
The alarm is received at the personal emergency
signal centre immediately after being transmitted by
the radio set. The personnel at the personal emer-
gency signal centre begins to initiate emergency
measures.
