Why is my keypad beeping or showing a trouble light?

Most keypads beep or light up a trouble indicator when something needs attention, such as a low backup battery, a power cut or a lost phone or internet connection. Your user guide explains what each light or code means on your model. If it keeps happening, or you are not sure, call your installer or monitoring company.
