5.3.3 Switch Off time
This parameter is associated with contacts coming from the outside. When a contact
keeps closed (or opened) for a period of time equal to or longer than the Switch Off
Time, Discovery changes over the audio signal to the following channel defined in
the menu of priorities.
If the control on the detection of the stereo sub-carrier has been enabled by means
of the jumper, the off time is the same as the commutating time associated with
the on/off contacts (only MPX).
5.3.4 Restore time
This feature determines the period of time during which the audio signal has to
keep within the parameters to be sent again to the output stage. This time is reset
if during the restore time itself, the signal is missing for a period equal to or higher
than the Analog off time or Switch off time parameters. If, when the restore time is
elapsed, the channel status fails, the restore timer stops at the end of the
corresponding time; if the channel restores before off times elapse, it can be sent to
the output stage; otherwise the restore time will be reset.
5.3.5 Analog Low Level
This parameter determines the threshold level that is lower than the audio and
below which the Analog Off timer is enabled.
5.3.6 Analog High Level
This parameter determines the threshold level that is higher than the audio and
above which the Analog Off timer is enabled.
To change the detection parameters, operate as follows:
1) Move the cursor to the Var menu and press key OK.
2) Using arrow keys move the menu to the field concerned and press key OK.
3) Using arrow keys, scroll the several configurations and press key OK.
4) Press key ESC and go back to the previous menu.
5) Repeat point 2 to change another parameter.
