Carbon Monoxide Detector Troubleshooting
Wireless Troubleshooting
Your carbon monoxide detector/sensor is designed to monitor the levels of CO gas in residential dwellings and give early warning when potentially dangerous levels exist. This troubleshooting information refers to the wireless Honeywell 5800CO. Additional information is available in the 5800CO device manual.

| State | Green LED | Red LED | Sounder |
| Normal State Indicates the alarm has power and is functioning properly. |
Blinks every 10 seconds | Off | Off |
| Alarm/Test Signal | Off | Will blink once every second. | Repeats a pattern of four short beeps followed by a 5 second pause. When conditions are normal the detector will self-restore to the previous mode. If needed, the sounder can be silenced for five minutes by pressing the “Test” button. The red alarm light will continue to flash in temp-4 pattern. If carbon monoxide is still present after the 5-minute hush period, the audible alarm will sound. The hush feature will not operate at levels above 350 ppm (parts per million) carbon monoxide. |
| Low Battery | Off | Will blink every 45 seconds for 37 days. | After the red LED has been blinking for 7 days, the sounder will begin chirping every 45 seconds. The chirping will continue for 30 days or until the battery is replaced. If a low battery is detected, the transmitter sends a low battery message to the control panel, which beeps and displays the detector’s zone number. Pressing the test button during this time will silence the chirps for 12 hours if no other trouble conditions exists. |
| Detector Trouble | Off | Will blink every 5 seconds. | Will chirp every 45 seconds. The detector will send a trouble signal to the system panel. Trouble conditions include an open circuit, tamper condition and sensor end of life. |
| Detector end-of-life | Off | Will blink every 10 seconds | Will chirp every 45 seconds. When the detector has reached the end of its life, the detector will send a trouble signal to the panel. This indicates that the CO sensor inside the detector has passed the end of its life and the detector must be replaced. This detector’s lifespan is approximately six years from the date of manufacture. |
| Detector powering up | Red and green LED will blink together four times, once every 10 seconds. | Off | |
Hush feature: The 5800 CO has a hush feature that can be used to silence the audible alarm for up to five minutes by pushing the Test button. The red alarm light will continue to flash in temp-4 pattern. If carbon monoxide is still present after the 5-minute hush period, the audible alarm will sound. The hush feature will not operate at levels above 350 ppm (parts per million) carbon monoxide.

| State | LED | Sounder |
| Normal State Indicates the alarm has power and is functioning properly |
Will be illuminated green. | Off |
| Alarm/Test Signal Indicates dangerous levels of CO. |
Will be illuminated red. | Will sound 4 rapid beeps every 5 seconds. Pressing the TEST/HUSH button will silence the alarm for 5 minutes. WARNING: When the unit is in trouble mode, there is a chance that the sensor may not detect CO levels. |
| Detector Trouble | Will flash amber every 30–60 seconds. | A chirp will follow each LED flash. |
| Detector end-of-life Replace the CO detector as soon as possible. |
Will flash green every 1-2 seconds. | Will chirp every 5 minutes. Pressing the TEST/HUSH button when in this state will silence the alarm for 36 hours. |
