Personal emergency signal functions 121
Technical alarms and faults
Warden control mode
The warden control mode is used to log check points during an inspection round if
you are working as guard personnel. The radio set can be programmed with the set-
tings required for this purpose. During programming it can be defined which emer-
gency signal functions shall be active in the radio set.
With the warden control mode active, the radio set will react as follows if it reads the
code of an inductive localisation beacon (IOS):

The code is signalled acoustically (if programmed).

The code is displayed on the display.

The code is transmitted to the personal emergency signal centre.
TIP
Radio sets with active warden control mode are typically specially marked. If neces-
sary, ask the responsible system administrator of the personal emergency signal
system whether the warden control mode is activated on your radio set.
Technical alarms and faults
Fault messages and technical alarms signal that a personal emergency signal unit is
either non-functional or functional only with restrictions.
Technical alarms
The personal emergency signal centre sends out cyclical status requests. The perso-
nal emergency signal unit must respond to these status requests. If there is no status
request from the personal emergency signal centre or no feedback from the radio set,
a technical alarm is triggered both at the centre and on the radio set, provided this is
technically possible.
Typical causes include:

No feedback because the radio set is defective.

No status requests because the personal emergency signal centre is defective.

No radio connection between the radio set and the personal emergency signal
centre because the radio set is out of radio range.
