The Moen AC Adapter Service Kit for MotionSense allows you to connect your MotionSense faucet directly to a power outlet. The AC power adapter in this kit can be used instead of the battery pack for the MotionSense 7594E, 7185E, 7565E, and S72308E series faucets to ensure yours is always connected to a power source. The Moen AC Power Adapter installs easily by plugging into the control box of your MotionSense faucet. The included Power Splitter allows you to connect both the AC adapter and battery pack to ensure battery backup if there is a power outage.
