The recalled alarms can sound a "double chirp"/fault alarm in the presence of CO, prior to going into full alarm. Upon hearing a double chirp, the Owner's Manual instructions recommend a consumer take the alarm out of service, which could expose consumers to hazardous levels of CO and suffer injury or death.

The recall includes FireX branded 10000 and 12000 series alarms with item numbers: 10000, 12000, 12000C, 12000-6, 12200, 12220, 12400, 12400C manufactured between June 1, 2007 and February 1, 2008. The date code appears on the back of the unit with a four digit year, three digit month followed by the day (ex: 2007JUN1 for June 1, 2007). Units with a manufacture date code prior to June 1, 2007 are not included in this recall.

These alarms are sold at commercial electrical distributors and electrical contractors and builders for installation into new home construction. A limited number of units were sold at Menard's nationwide from June 2007 through February 2008 for about $20 (10000 series) and $30 (12000 series).

Consumers should contact Maple Chase immediately to receive a free comparable replacement alarm and make arrangements to return their recalled alarms. Until a new alarm is received, consumers should test the batteries in the alarm weekly by pressing the "test" button. If the alarm signals a low battery alert, consumers should immediately replace the batteries. Consumers should not remove their alarms until they have received a replacement alarm.
