Having problem with my pager alarm

I had my Black Widow 7150 (2 way pager) installed by a mechanic. He used the diagram that came with another Black Window alarm that was made 4 years ago Not pager alarm though). My main problem is that the remote works fine, it starts the car and what not. But the pager does not do anything at all, it does show lock, unlock and when the car is started, other than that it does nothing! The pager works when it feels like working. The mechanic did use a wiring diagram from his computer for my 95 Integra. But my alarm system did not come with a wiring diagram for itself. I hope someone can help me out and I would appreciated. The alarm is: Black Widow 7150 w/starter kill and shock                    sensor. It is installed in my 95 Acura Integra Sedan (automatic). Once again thanks!
