Security and fire alarm system installers configure and mount security and fire alarms in private homes and businesses.

Security and fire alarm systems installers help people protect their property.

Before installation, installers talk with clients to discuss what type of security system would work best and to provide cost estimates. They install the system referencing building plans and system manuals. They drill holes in walls, ceilings, and floors so that wires can be threaded through and connected. They mount cameras, sensors, and control panels.

After installation, installers program and test the security system and make adjustments as needed. They teach clients how to use the system.

Installers also perform maintenance and repairs on installed security systems. They examine systems to locate problems such as loose connections or broken insulation. They may order replacement parts.

Installers also stay up-to-date on new products and technological developments in the field.
