CO alarm chirps once a minute and the Fault LED flashes once a minute

Possible cause: 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.
