Where there is smoke
Electrical Tip of the Day: Smoke detectors are an important part of any electrical system. Ideally they should be powered by 120 volts AC, have a battery back up system, and be interlinked. Smoke detectors should be located withing 4′ of each bedroom door, in or near stairwells, in your mechanical space, in your attic, in your garage, and in your basement / crawl space. If you have questions about fire safety your local fire department can be consulted at no charge to do a walk thru and help you out.
