Loss of supervision on Honeywell Carbon Monoxide detector
If a 5800CO detector is showing a loss of supervision, this means that for whatever reason, the sensor is not being monitored by the alarm panel. To ensure that the sensor is being monitored properly, perform the following troubleshooting steps.
Perform a Walk Test on the sensor. If the sensor trips on the panel, it is being monitored. If not further troubleshooting will be required.
If this sensor has a history of low battery, the battery may have died completely, and is no longer being monitored as it no longer has power. If this is the case replace the battery in the sensor. If you do not know how to do this read the "How to change the battery in the Honeywell Carbon Monoxide detecor" article.
Ensure that the sensor is within range of the panel. It needs to be within 150 feet of the panel, with minimal interference, (walls, doors, etc.) If signal strength is the issue, you can confirm that by performing a Go no Go test.
If none of these reasons explain the loss of supervision of the sensor, you will need to contact our Technical Support department for assistance.
If you ever receive a false alarm on your 5800CO detector, leave the home, and contact our Technical Support department. The 5800CO detector is a life-saving device, and alerts from it need to be followed to ensure that your family is safe.
If your Carbon Monoxide detector is beeping, one of three things is happening, either it is going off due to a carbon monoxide alarm, the battery has been low for 7 days, or the detector is at the end of its life.
If the battery is low, and you are being alerted to it by the sensor chirping every 45 seconds, you will want to replace the battery in the sensor as soon as possible. If you do not know how to do this read the "How to change the battery in the Honeywell Carbon Monoxide detecor" article.
If the battery in the sensor is not low and it is beeping because it is at the end of its life, you can purchase a new one by contacting our Technical Support department.
