Thank you all for the help. Since I had the DS10's on hand and had a few of them I wanted to go with those components although several of you use the universal module and/or reed switchs with power flash modules which I am sure are more robust. But now I know it can be done with the DS10's alone, and I will try it with one instead of two. I had two so I tried that but I am having trouble mounting one and getting good contact.
I will also take Dave's advice and move the transmitter further away from the door, there seems to be some inconsistent transmitting. I did catch one of my problems, which is so obvious, is when I was registering the DS10 I had to go through a door to get to the garage to push the test button. The door is wired for security so that DS10 was sending the signal to the AHP before I even got to the one in the garage. duh.
Anyway, still trying to get it to work by adjusting magnets. I have gotten closer, and will take the comments posted here to make some further tweaks. I have my notes ready for the next weekend. Thanks again.
