Basically, you can get any aftermarket alarm to work along side the smartlock module.
I think though, what you are more likely after, is how to get the alarm to do the little things such as turn on the interior light when its disarmed, switch it off when its armed, lock / Unlock doors, and open the boot.
There are other features you can try and intergrate the alarm with, but these depend on the functions of the alarm.
(Eg auto door locking when car is in motion (Anti hijacking), auto unlocking doors and lighting interior lamps when car stopped, and ignition off. Automatically winding up windows when alarm is armed, etc etc.
Anyway, first thing you will definitely need is a wiring diagram for the alarm. Something I havent got for this model.
Secondly, you must not wire the cutout relay on the alarm, to any of the smartlock data lines, from the ignition key, to the smartlock, and also from the smartlock, to the EEC module.
Smartlock already has a relay to the starter motor, so wiring the alarm cutout relay to this line may be usless.
If you want further info then send me an email, as I have done this to 2 EF's so far. Not hard, but takes a long time to wire !!!
