Looks like you have the 3 sensor inputs (2 analog and one 1-wire) enabled and they are floating. Either disable them or ground them. If enabled as alarms, they should have a threshold higher than what they would see when grounded. In other words, place a larger number in the alarms. The best bet if you are not using these inputs is to ground the 2 analog inputs and disable them through the configuration register. To explain what you see: when analog inputs are enabled as alarms, they fucntion as iputs 5 and 6. The 1-wire functions as input 7.
