The Smart Light Outlet will turn on a light when triggered by the Cordless 24" x 48" Floor Mat. The Cordless Monitor will alert a caregiver in another room. The Smart Light Outlet allows you to plug in any standard lamp or light source to create a safer environment by providing illumination when someone gets out of bed. The light will remain on until the outlet has been reset by the caregiver. This package included a Smart Light Outlet,a Cordless Floor Mat and a Cordless Monitor. Packages are also available with a Bed Pad instead of a Floor Mat. We suggest an AC-04 adapter as an alternative to frequent battery replacement. Sold separately.
