Does a State Child Services order supersede a County Restraining Order?

I'm the Foster child relative placement for my 3 nephews. I've been caring for them for a month during an accusations of abuse investigation. The Mother went to the children's school & accused the Father of abusing the children, she claimed she was suicidal over the incident & feared for the children's lives. The school immediately called the police and child protection services. The children were placed with me during the investigation. The children have had the well child exam required by child services, they’ve been interviewed by the County Sheriff investigator as well as the Father has also. The Father received a letter from child services stating the accusations of alleged abuse by him were unfounded. The child services has approved unrestricted visitation for the Father and restricted supervised visitation for the Mother. Both have had 2 visits with the children with no issues. 2 days ago the Father received a County restraining order from the Mother, naming the children, the premises & possessions. It was based on the already investigated alleged abuse. It was served by the County Sheriff. The couple are not married. She is not a U.S. citizen, the Father is a U.S. citizen and an Enrolled Native American. The children are U.S. citizens and Enrolled Native Americans as well. Does the visitation order still stand after receiving the recent restraining order made by the Mother? She has been living at a safe house during this time and the Father lives in the home he pays rent for.
