ESL and Interlogix recall fire alarms

The Edwards (ESL) and Interlogix brands are recalling 33 models of their 400 and 500 series smoke alarms, citing a tendency to malfunction.

According to the Consumer Product Safety Commission, the alarms have been found to fail to alert consumers of a fire due to radio frequency interference.

There have yet to be any incidents or injuries reported, however.

The recall affects about 141,000 units in the U.S. and 13,000 in Canada of the 400 and 500 series Edwards (ESL) and Interlogix branded smoke detectors, which are identical. They are round, white and are about 6 inches across, with date codes 13084 through 14059.

The CPSC urged consumers to contact their security or fire system providers if they suspect they have may have an affected unit. Consumers can receive free replacement and free installation of new smoke detectors.

The Chinese-manufactured alarms were sold through contractors, dealers and installers for use in commercial buildings, hotels and motels, apartments, dormitories and homes between March 2013 and February 2014.
