Device ID 18 is showing Malfunction, which indicates the sensor is not communicating. How far from the panel is the sensor?
Under normal operation, the LED should be green. The LED will flash amber 1, 2, or 3 times to indicate specific faults.
Can you check the sensor to ensure that it is a 2GIG-CO8-345 and not a 2GIG-CO8E-345? Records show the legacy version was purchased and sent but it wouldnt hurt to double check.
If you have not done so, remove the sensor from programming and check the batteries to ensure they are charged and within their printed date code. Then reprogram the sensor.
