I needed to lower the sensor in my living room so I could put up coving unfortunatly the wiring wasn't long enough so I lenghened the wires , making sure I connected all the wires correctly . Now I haven't got power to any of the sensors nor the hallway key pad. Is there a reset button in the main panel or may I have blown a fuse or something , can anyone please help.. The system is scantronic 9448+
