What Does a Security Alarm Installer Do?

Security alarm installers are the problem-solvers who keep your home or business safe.

Security alarm installers — also called security system installers, home security technicians and security alarm technicians — install home security systems, fire alarms and other safety devices, such as carbon monoxide detectors. 

Installers follow blueprints and building plans to determine the most efficient way to install the necessary equipment. 

In today’s smart homes, a security system has many elements, including control panels, door and window contacts, sensors, video cameras and the wiring needed to connect the components. Security alarm installers install all these elements, following safety codes and ensuring they work together.

The ability to trouble-shoot hardware, software and network issues is a key skill for success in this career. Good customer service skills are also important to make sure the client is happy with the installation and understands how the system works.
