Pressing the test button on the smoke alarm produces no sound, or the status light stays solidly on or off rather than blinking every 40 seconds outside of an alarm state.

Look it over for damage, confirm the right battery type is fitted with its cover off and properly connected, and vacuum the unit gently with a soft-brush attachment. Fit a new battery. Don't attempt repairs if that still doesn't fix it - the smoke alarm itself needs swapping out.

CO detector gives a single chirp every minute, continuing for up to 30 days - a fault or low-battery warning.

Possible cause: Incorrect sensor/circuitry settings or low batteries.. Put fresh batteries in. Still chirping despite that and the product's still under warranty? Contact technical support for advice. Once it's out of warranty, replace the unit straight away instead.

Bailey Smoke & Carbon Monoxide Alarms

(2026 Model Year, Motorhome & Campervan)

Sourced from Bailey's 2026 model year owner's manual for the Motorhome & Campervan range. If your motorhome or campervan is a different age or range, some details — such as the exact control panel brand or chassis-component generation actually fitted — may not match. Always cross-check against the handbook that came with your specific motorhome or campervan.
