## Abstract

The U.S. Department of Energy (DOE) is publishing this technical amendment to exclude external power supplies used in specific applications from certain energy conservation standards prescribed under the Energy Policy and Conservation Act (EPCA). Congress enacted this exclusion, which applies to external power supplies used either in security or life safety alarms or surveillance system components, earlier this year. DOE is also modifying its current certification requirements to make them consistent with this change.
