How does it Work?

1. Green LED: Flashes every 30 seconds to indicate the unit is operating properly. The green LED will also flash before CO reading is taken and when any button is press.
2. Red LED: When a dangerous level of carbon monoxide will detect the red LED will pulse and a loud alarm pattern will sound. The carbon monoxide alarm pattern is 4 short beeps, followed by 5 seconds of silence, followed by 4 short beeps with a corresponding red LED flash. This cycle will continue for 4 minutes and then change to 1 cycle every minute until the device is reset or the CO is eliminated.
3. Test/Reset button is designed for weekly testing if it works properly and reset the unit during CO alarm.
4. Alerts users when batteries need to replace.
