Since 1960

A family company with over six decades on the alarm panel.

Certified Alarm Company of Alabama was founded in 1960 and is family and locally owned and operated. The shop sits at 2904 N Jackson Hwy in Sheffield, with the company's yellow shield painted on the garage door.

The company designs, installs, inspects, services and monitors its own systems: fire alarms, intrusion and hold-up alarms, cameras, access control, personal emergency devices and the security equipment that banks need. It works with residential, commercial, industrial and medical customers, and answers emergency calls every hour of every day.
