Detectable Warning


What is a Detectable Warning?

Definition of Detectable Warning in Construction

A detectable warning is a descriptive term for any material that provides a warning that is either accomplished by feel, sound, light, etc. In most cases the description is used on site plans to identify the handicap ramp ” dimple ” material that is installed within the sidewalk areas that are specifically used by handicap individuals. In other cases, door knobs with special knurled surfaces or emergency horns and strobes are all detectable warning devices.

The American Disabilities Act ( ADA ) will identify the necessity for detectable warnings in accordance to their rules and regulations for handicap access. The Fire Marshal will be responsible for the identification, as well as locations of horns and strobes for emergency fire or smoke alarm compliance.
