Moen 177565 AC Adapter Service Kit for Moen Kitchen Faucets with MotionSense Please note that when using this AC Adapter, we recommend plugging it into an outlet that is not controlled by an ON/OFF switch. If the AC Adapter is plugged into the wall outlet designated for a garbage disposal, oftentimes that outlet is controlled by a switch, thereby not allowing the MotionSense faucet to function when the switch is in the OFF position. Supplies steady, reliable power to hands-free MotionSense faucets Compatible with MotionSense 7594E, 7185E, 7565E, and S72308E series faucets Replaces battery pack so MotionSense is always connected to power Easy to install
