Pre-Install Checklist:

  • • Carbon monoxide detectors should not be mounted on the ceiling. Carbon monoxide is heavier than air and sits down closer to floor level.
  • Position at least 6 inches from the ceiling but not lower than a light switch.
  • • Place within 10 feet of a sleeping area, such as inside of a bedroom if it contains a fuel burning appliance.
  • • Place on every floor of the building, ideally in any room that contains a fuel burning appliance.
  • • If the appliance or the room is not normally used, such as the boiler room, the detector should be placed just outside the room so the alarm can be heard more easily.

Installation Steps:

After you program the Honeywell 5800COMBO smoke/heat/freeze/carbon monoxide detector to your panel and before mounting permanently, conduct a test to verify adequate signal strength. Adjust the device location as necessary.
