I hope this helps you as its a video showing the use of the meta alarm (metasystem) on a 2010 Moto Guzzi Bellagio luxury.
When I first bought the bike I was not sure how to use the alarm. There was no videos that I could find to show how to use the alarm. In the first few days it was difficult to start the bike or when leaving the bike and knowing how to start.
They are simple to use with a single press of the key fob. The alarm sounds once and the alarm is unarmed. The red led light goes out. The bike can be started up as normal.
On leaving the bike. A sound is made and the alarm triggers. The indicators flash and the bike alarm is armed. The red led flashes to say it is in a armed state.
I also put videos on vimeo and youtube:
