CPSC campaign 06151
Hazard
These alarms can drain the power from batteries rapidly, causing premature low battery power. Consumers will be alerted to the low battery power and the need to replace the battery by a chirping of the unit. If the batteries on the smoke/CO alarm are not replaced before the battery power terminates, the alarm will not detect smoke in the event of a possible fire and the presence of carbon monoxide.
Remedy
Consumers should contact First Alert Inc./BRK Brands Inc. immediately to receive a replacement alarm. 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.
