If you wanted to install an electric reverse lockout on the DA10 Demco actuator part # DM8102222 you would want the part # DM11993. This is confirmed to fit DA10 actuators like this. When this solenoid has power on it would prevent hydraulic pressure from building in your brake lines and assemblies.

There isn't a manual lockout for your actuator.
