According to Texas Fire Rules, which of the following is NOT exempt from licensing?

The assertion that licensed alarm technicians are exempt from licensing is not consistent with Texas Fire Rules. Licensed alarm technicians must hold a valid license to operate legally within the state. This regulation ensures that individuals responsible for installing and maintaining fire alarm systems meet specific training and competence standards essential for safety.

On the other hand, individuals installing systems on their own property are often exempt from needing a license, as they are not installing alarms for others. Employees of a registered firm would also typically be covered under the firm's licensing while performing their duties. Likewise, anyone selling fire equipment through mail order is engaging in a different business model that may not require them to hold an alarm installation license, thus potentially qualifying them for exemption. The distinction emphasizes the importance of licensing for technicians directly involved in fire alarm systems to ensure public safety and compliance with regulatory standards.
