N.C. Gen. Stat. § 74D-14
An alarm systems business may not maintain any action in any court of the State for the collection of compensation for performing an act for which a license or registration is required by this Chapter without alleging and proving that the alarm systems business is appropriately licensed and the employee or agent of the alarm systems business is appropriately registered upon entering into a contract with the consumer. An alarm systems installation, maintenance, or monitoring contract entered into with a consumer shall be void if the consumer confirms through records maintained by the Board that the alarm systems business is not properly licensed or the consumer establishes through records maintained by the Board that the person enticing the consumer to enter into the contract is not properly registered by the Board. The sale, installation, or service of an alarm system by an unlicensed or unregistered employee shall be deemed an unfair and deceptive trade practice and shall be actionable under Chapter 75 of the General Statutes.
