Pandora Alarm, Smart Pro UK

Hi all, Had to get a new alarm fitted to my Hilux insurance insisted and would not allow me to fit a clifford or similar cat1 alarm myself and certify despite doing this for past 10years as a side line business As it happens somone tried to steal the car last week and the alarm stopped them in there tracks still did damage but least the car is still here So since then it’s got me thinking about extra features to add now. Has anyone fitted these Pandora alarms and can tell me if you have to program the the extra outputs like CH11 for external siren ? I was thinking of using this to trigger external lights on the car like marker lights and roof bar lights maybe through a pulse circuit to make everything flash along with a few more sirens hidden in the chassis etc
