Washington, D.C. -- In cooperation with the U. S. Consumer Product Safety Commission, Electro Signal Lab, Inc. (ESL) of Rockland, Massachusetts, today announced a voluntary recall affecting approximately 500,000 of its smoke alarms, some of which may not sound or fail to sound loudly when smoke is present. These alarms were manufactured in both 120V AC and battery-powered models and may be installed in hotels, motels, apartments, institutions and consumers homes, There have been no reports of any injuries associated with this problem.

The alarms are circular in shape with an off-white plastic cover, and a white test button that lies flush with the cover's face. The brand name (ESL, ADT, Aritech, or Edwards) and the words "Smoke Alarm" appear in raised lettering just above a half-moon-shaped grill on the face.
