Carbon Monoxide (CO) Alarms
Check against the official notice below — it lists the full affected range.
The ESL SafeAir 240-COE Carbon Monoxide alarms sold between November 2000 and August 2002 are being recalled because they fail to detect carbon monoxide after one year of operation due to an internal software error. These hard-wired units do not alert users when they stop working, even when the test button is pressed. The white, rectangular alarms are approximately 6 inches long and 2.75 inches high and have "CARBON MONOXIDE ALARM" and "DO NOT PAINT" printed on the front. The back of the unit displays the model number "240-Coe," the company name "SENTROL," and a four-digit date code ending in "T" that indicates when the unit was manufactured.
To determine if your alarm is affected, check the date code on the back of the unit. Only alarms manufactured between the 45th week of 2000 (date code 0045T) and the 35th week of 2002 (date code 0235T) are included in this recall. If your unit falls within this date range, you should contact your system installer or service provider to arrange for the free installation of a replacement CO alarm.
