Smoke/Carbon Monoxide Alarm
A Smoke and Carbon Monoxide detector is both insurance and peace of mind. It is always ‘on.’
We also have this Carbon Monoxide detector in our bedroom.
Having two detectors/alarms in the Airstream is part of our defense plan against carbon monoxide poisoning.
We always check the “on” light before we go to sleep.
