alarm pager

[Synthesis5]

i have an alarm on my car right now(hornet) which is programed so that i still can use the the original keypad thingies that came with the car. so could it be possible to buy/add one of those pager thingies to my allready existing alarm. like, all i want and want to know, is if its possibly to upgrade my alarm with the pager??? i know it might be confusing but im not to bright on these new alarm things.
