Summary

[edit]
Description An eight second sample for the standard fire alarm sound in North America, as specified by the NFPA. This and its variants are used to warn others of a fire. The sound sample uses a 500Hz square wave each separated by a half a second gap. A one and a half second gap is present between the third pulse and the fourth pulse. Different fire alarm systems may have variants on this standard pattern.
