I seem to have fixed the problem with false alarms. For this, I placed 2 of them almost back to back (their backs at an angle) and covered most of their eyes with black tape.
Have patience with me, I just have 6 more door/windows sensors and the siren to install. I may not have enough channels left - how do I find out if I don't? And if not, should I install an extender? Or another Home Security base? The remaining windows are in the basement, and I know that at least the back door sensor works. I have bars installed, but a friend who was a maintenance person tells me that bars and their lock can be broken into in a few seconds.
I am so glad that the movement sensors work. After reading some comments here I thought that I would never get them to work.
How does one subscribe to a particular discussion? I am getting a conversation I did not subscribed to.
The above worked for 3 days. Now, I cannot even arm the system without getting the Movement sensors acting up. I thought that pressing just Alarm Home would leave the MS out, and that the key ring only armed D/W sensors. But it does not seem to work this way. I am going to have to reset the entire system, and unless there is a solution, I will leave the movement sensors out. A pity, I hope that a solution is forthcoming.
