Can a firefighter legally sell and install fire systems without a license?

In Texas, the law requires individuals involved in the sale and installation of fire alarm systems to hold a proper license. This is primarily for public safety and to ensure that installations meet the necessary codes and standards. Having a certification or training, while beneficial, does not replace the legal requirements set forth by the state regarding licensing. Thus, a firefighter or any individual cannot legally sell or install fire systems without obtaining the necessary licensing credentials from the appropriate regulatory body. This requirement helps ensure that installations are conducted safely and effectively, protecting both property and lives.
