Abstract
Newly installed electrical units emit, for a brief install interval, an “installed” output either audibly or visually, or both in response to an install mode input signal. After the install interval, the “installed” output ceases. As more units are installed, the earliest installed units remain silent in the presence of the install mode input signal.
