Fire alarms, smoke detectors, and carbon monoxide detectors are all great first lines of defense against fires. They let residents know there is a problem and ensure everyone escapes safely. While a sprinkler system isn't a necessity for residential buildings, state and local ordinances often require them. They help suppress fires once the fire reaches a specific temperature. Service 1st Fire Protection LLC sells and installs fire sprinklers for both residential and commercial properties to use in the event of a fire.
