ESL/Interlogix Smoke Detectors Recalled

View all
Lilibeth Ramirez3 years ago

ESL and Interlogix brand smoke detectors sold from March 2013 to February 2014 have been recalled.

About the Recalled Smoke Detectors

According to the Consumer Product Safety Commission (CPSC), Edwards (ESL) and Interlogix brand smoke alarms have been recalled due to radio frequency interference which can cause the smoke detectors to fail to alert consumers of a fire.

A total of 154,000 units were sold—141,000 in the United States and 13,000 in Canada. CPSC recommends consumers contact their security or fire system provider immediately to determine if their smoke detectors are included in the recall.

Consumers should not take the alarms out of use until the replacement alarm has been installed. Only professional installers should remove and replace units.
