Anti-Alarm

For almost a year I have a 5080 with nearly 20 different sensors (smoke, window, IR) in operation and has always been very satisfied.
Only the motion triggered (despite exchange and assistance Help) every now and then a panic alarm and had to be taken out of the system.
The window and door contacts, and smoke detectors, I never had any problems. Not once did the countdown in a doorway from smoke detectors reported straight away with minimal smoke plume - very good!
Since I missed an external siren and found the flexibility by the internal GSM module interesting upgrade for 9030!
In short, at just 100 release experiments (no kidding) 15 messages!
Regardless whether distance to the receiving unit was 15 meters or 2 cm, the batteries old or new, with or without power supply, with or without a SIM, with or without
external GSM antenna, triggered with or without batteries in outdoor siren directly or waited longer.
As tempting as the product description may sound at the very worthwhile predecessors, so bad the product!
Due to the multitude of my fellow sufferers a faulty main unit is excluded, especially since I was able to try a second.
Incidentally, to the 6 Series have the same problems, if necessary overlay problems through radio external siren ??
I agree with the statement of an earlier review and confirm that such a product conjures only a sense of security and in an emergency with a high probability to be not alarmed.
