Security systems installers and workers install, maintain, and repair security and alarm systems, devices, and equipment. They use blueprints for reference to electrical layouts and building plans. They use various tools and methods to install components such as control panels, window and door contacts, sensors, or video cameras and electrical and telephone wiring. When the work is done, they explain to customers how to use the system, demonstrating the steps to take and what to do when a false alarm happens. Installers and workers also make sure circuits and sensors are working. They feed cables through spaces in walls, ceilings, or roofs so that they reach fixture outlets.
