Homeowners are being warned to check their alarms after manufacturer Sensor Safe confirmed there was a potential safety issue with its SF80190 model.
The devices in question - which have been supplied throughout NI - have now been removed from store shelves and all existing stock has been quarantined.
However "a large number" of them remain unaccounted for.
Limavady Borough Council's Environmental Health Department released a statement after it was contacted by Sensor Safe Ltd.
It said: "Test results have confirmed that these alarms may not detect levels of carbon monoxide and as a result have been taken off sale.
"All existing stock has been quarantined while recalling those already sold. These alarms have been supplied throughout Northern Ireland.
"There remains a large number of these monitors unaccounted for throughout Northern Ireland, please ensure if you are in possession of the above carbon monoxide alarms to stop using them and return it to your supplier immediately."
The company has apologised for any inconvenience caused.
