About 141,000 ESL and Interlogix brand 400 and 500 series hard-wired smoke detectors are being recalled because radio frequency interference can cause them to fail to sound an alarm during a fire. These white, 6-inch round detectors were professionally installed in homes, apartments, schools, and commercial buildings as part of integrated security systems. While no incidents or injuries have been reported, the failure of a smoke alarm to alert occupants to a fire poses a serious safety risk. Customers should contact their security provider for a free replacement and professional installation of new units.
Internal radio frequency interference can prevent the detector from functioning properly, meaning it may not alert consumers to the presence of smoke or fire. This failure to sound an alarm significantly increases the risk of fire-related injury or death.
Customers should immediately contact their security or fire system provider to determine if any of their units are included in the recall. If so, they will receive free replacement and free installation of new smoke detectors. Consumers should not take the alarms out of service until the replacement alarm has been installed. Only professional installers should remove and replace these units.
