Error Code / IndicatorSymptom / MeaningPossible CauseStep-by-Step DIY FixSuggested Actions
N/A
The carbon monoxide detector emits a single chirp once a minute and its Fault LED flashes yellow once a minute, and can keep this up for up to 30 days
The detector's continuous self-check has found the sensor/circuitry settings to be incorrect, or the power pack has become low
If the detector is still within its warranty period, contact technical support. If it's out of warranty, replace it immediately - its power pack is sealed in for the product's life and can't be replaced on its own, and the sensor itself should be replaced after 7 years from installation regardless.
DIY Check / Tech Fallback
N/A
CO alarm chirps once a minute and the Fault LED flashes once a minute
The detector's own self-check has found an issue with its sensor/circuitry, or its power pack is running low - this can carry on for up to 30 days.
Because this detector's power pack isn't user-replaceable and is rated for the product's whole lifetime, a fault signal like this usually means the unit itself needs replacing - contact your dealer for a new detector.

Frequently Asked Questions

Q: How do I maintain and test the smoke alarm?ⓘ

The smoke alarm runs off a single 9-volt battery, which under normal use should last around a year. A red light blinking every 40 seconds tells you the unit is powered up, and if you hear a chirp at that same interval, that's the low-battery warning - you'll get about a week's notice before it needs replacing, and it's worth doing so promptly since a flat battery means no protection if there's ever a real fire.

A sensitivity test button checks the circuitry, battery, and horn all in one go - it's worth using this after the vehicle's been in storage, before setting off on a trip, and roughly once a week while you're using it. For general upkeep, give the alarm a gentle vacuum with a soft brush attachment every three months or so to keep it working properly.
