The easy answer is no.
Here is a question worth considering .Are you wiring your own powerpoints as well? If the answer is no, ask yourself why. Then think about the role an alarm system plays in your life.
You are obviously trying to save a bit of money but it seems to me that you are potentially throwing quite a bit of it away on a potentially unreliable system, that (even if working beautifully) relies on you being able to receive a call. Also, when that siren's ringing due to a false alarm in the backyard caused by an outdoor sensor placed by an inexperienced DIYer, I'd hate to be your neighbour.
