thanks it's working now after leaving it alone for a few minutes with the batteries still in.
I move don to test the PowerHorn (OMG that hurts the ears when not wearing earplugs!) and the lamp modules.
Again I ran into the same issues of neither working even though I set the HC and LC correctly. (HC=B; LC=14)
So I figured I take a break and left everything on (connected to the power outlet). The SC1200 and the PowerHorn and Lamp Module were all on an extension core connected in the same outlet BTW.
In any case I came back a hour latter and tested the lamp module again via the SC1200 14 on, 14 off and it worked! Triggered the alarm and the lamp module worked as well! The same occurred with the power horn!
So perhaps the items need to "charge" on the power outlet for a bit no idea. In any case now I just have to test the other 10 switches, 3 horns, and 3 lamp modules before I go an install it all over the house and re-test.
Thanks to some pre-reading I know that the small keychain remotes KR10A the LIGHTS ON/OFF buttons will cause **ONLY** the LC = 15 to turn on/off (ie. that is my LC + 1 number). While the Security Remote Control (SH624) security lights will turn on/off LC= 14.
Now that makes no sence but oh well.
If I read the instructions right for the Security Remote Control (SH624) the numbers 1, 2, 3, and 4 are so I can control lamp/appliance modules with LC = 1, 2, 3 or 4 correct?
Not sure I see a benefit to the Security Remote Control (SH624) vs the keychain remotes KR10A from a "security arming/disarming" stand point. I guess I will be using the keychain remotes KR10A and/or the SC1200 when I have to interact with it. The Security Remote Control (SH624) seems more like something you would use if you want more automation. It's just too big for my use.
But so far so good. Now I'll get some dinner and continue this fun stuff later. My family is already looking at me like I am crazy with all the noise coming out of the basement.
