Anyone using similar alarm, just installed mine and have some doubts.
First: There's one small square piece so call window sensor placed at the window, does the led on this piece lights up? it seems that mine doesn't and the installer dare to tell me that it is just a sensor and there's no light.
Second: the shock sensor comes with a black and white adjustable knob. these two knobs are use to adjust what?? The installer told me one is use to adjust the sensitivity which i believe is the black knob while the white knob is to adjust how long the warning will last.
need to clarify my doubts so that i can go back knock table. the installer seems unfamiliar with the system and took quite some time to install and also keep refering to the manual.
