System Sensor has recalled approximately 1,450 i4 series combination carbon monoxide (CO) and smoke detectors, specifically models COSMO-2W and COSMO-4W. These detectors can fail to detect carbon monoxide gas in the home, which poses a serious risk of carbon monoxide poisoning. The affected units were manufactured between September 3, 2014, and September 13, 2014, and were sold by security equipment dealers nationwide. Consumers will receive a free replacement for the recalled units.
The internal sensors may fail to trigger an alarm when carbon monoxide gas is present, preventing occupants from being alerted to a dangerous gas leak. No incidents or injuries have been reported to date.
Consumers should immediately contact System Sensor to obtain a free replacement combination CO/smoke detector. Consumers should keep using the recalled detectors until replacement detectors are installed.
