Can I install my own carbon monoxide detector?

Drive the supplied screws partially into the ceiling or wall and line up the mounting base with these screws. Install batteries, place and twist the CO detector into position under the screws, tighten with a screwdriver and mount the alarm onto the base.

Where is the best place to install a carbon monoxide detector?

Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.

Why is the carbon monoxide alarm chirping?

The following conditions could cause your carbon monoxide alarm to chirp consistently: Low Battery Condition – The alarm will chirp once every 60 seconds to indicate the batteries need to be replaced. End of Life Warning – Seven years after initial power up, a Kidde CO alarm will begin chirping every 30 seconds.

How do you install a carbon monoxide detector?

Select a drill bit slightly smaller than the size of the supplied wall anchors to ensure a snug fit. Use the mounting base to mark the screw holes on the ceiling or wall and drill holes where marked. Gently tap the plastic screw anchors provided into the drilled holes with a hammer.

How often should a carbon monoxide detector be changed?

If you have a lithium ion battery model, change the batteries every 10 years or so. Clean each alarm with a vacuum once a year to remove any dust or particles that may have accumulated in the unit. Check the manufacture date on each unit periodically and replace them once they reach their expiration date.

How often should I test my CO detector?

Install batteries, place and twist the CO detector into position under the screws, tighten with a screwdriver and mount the alarm onto the base. Test your CO detectors at least once a month. On most units, this only requires the push of a button to test that the alarm sounds and the batteries are still working.
