KPH will trigger a SELF-ACTIVATION.
If the vehicle has an alarm system with an appropriate output signal, it can be connected
to the VTU. Triggering the vehicle alarm will then also generate a SELF-ACTIVATION.
SELF ACTIVATION ACKNOWLEDGEMENT
Once a SELF-ACTIVATION has occurred, the corresponding status LED on the switch
box will blink until the SELF-ACTIVATION has been acknowledged by the command
center, at which point the LED will glow steadily.
RESET ALARMS
The SELF-ACTIVATION condition can only be cleared from the command center after
the situation causing it has been addressed. Clearing the SELF-ACTIVATION
extinguishes the LED. The reset command clears all Self Activations currently in process
in the VTU, including those that have not been acknowledged.
