ADT encourages retailers and businesses to participate in Code Adam, one of the largest child-safety programs in North America. When a missing child is reported, a "Code Adam" alert is announced over the public-address system. A brief description of the child is disseminated and employees immediately search for the child and monitor all exits. If the child is not found within 10 minutes or if the child is seen accompanied by someone other than a parent or guardian, store personnel contact local law enforcement and request immediate assistance.
