Hi Guys
I am still dealing with the intermittent Open or Problem errors on my second SC1200. ....Anyone have a fix? .....
From my experience with 4-5 of these, I think it is 99% fair to say it is NOT a DS10/12 issue. I tried external antennas, rf ampflifers, adding a 3rd AA battery to nearly double the rf output of the sensor, none stopped the apparent semi-random blinking zones as sc1200 stops seeing them. I blame local WPAFB for the rf interference that I believe is over and above the background norm. From my experience, the sensors will not work consistently over about 5-10' max - so no way to use this system in any size home.
I believe my last installation is now reliably seeing all sensors. I had in wall ethernet cable throughout the office/garage and gave up and basically extended the sensor two wires to a central location and mounted the DS units on the wall next to each other with the sc1200 mounted with them. Now the rf distance is 1 foot.
This has been the only solution I found. I also use one of those old rf repeaters x10 used to sell that repeats security sigs also - so remotes sorta work most of the time.
Only way I got arm and disarm to be 100% was to have my ahp run timered routine to simulate one of my remotes - arm at x:00 pm, disarm at y:00 am. ahp is on external antenna which is still about 10' from the sc1200 now.
In order to know if the alarm actual sets, I ran the internal speaker wires into my in home phone line on the other 2 wires and have a couple speakers around to hear the dink sounds of arming or constant dink dink dink dink if it fails to arm at evening.
sorta defeats the easy wireless install main features huh?
