3.1.2.19 Lifextender
Setting and display screen.
The parameters relative to the Lifextender option can be monitored: equipment serial
number, equipment code (parameter to be notified to Elenos should the user require
the activation/deactivation of this function), activation/deactivation code (parameter
supplied by Elenos to be entered for the function activation/deactivation), function sta-
tus, work days in good operating conditions, work days in critical operating conditions.
The algorithm considers the following parameters to define the critical days: RF tem-
perature, power supply temperature, ambient temperature and reflected power with
respect to maximum operating power.
These parameters must exceed the threshold values for a certain amount of time.
In this way, the duration and intensity of the event is assessed: intense short events are
heavy; less intense but longer events are heavy too.
3.1.2.20 GSM and modem service
Setting and display screen.
The GSM signal field intensity can be monitored.
It is possible to enable the submission of an alarm by SMS and/or PSTN in case of no
mains power (No Mains SMS) for the period of time set (Delay).
It is possible to enable the submission of an alarm by SMS and/or PSTN if the power de-
livered is at least 3dB less than the target set (SMS FWD over 2/3).
The codes to be displayed in the different message strings can be defined (PagerId,
StatId, String Id).
