My scoob has a cobra alarm fitted, although I've got no instructions or info with it. It has the 2-button alien type remote which also unlocks/locks the doors. From what I can see on the siren under the bonnet it's a 7900 series alarm.

How can I find any more info on this system, such as model number and features? Also a manual or at least some basic instructions would be helpful, such as how to add new remotes or change the settings of the system.
