Page Count: 20
scope:

This Standard specifies the characteristics of acoustic signals to be used for audible emergency evacuation (E2) and audible evacuation signals with relocation instructions (ESRI). It applies to the audible signal only and not to the signaling system components or equipment. The use of these signals either as the only audible means of signaling or as a part of a voice message is subject to the requirements of governing laws, codes or other standards.

This Standard specifies parameters of the audible emergency signal, i.e., the temporal pattern, the required sound pressure level at all places within the intended signal reception area, and the spectral content for certain applications, in order for the audible emergency signal to be recognizable.

This Standard applies to:

• the audible signal that is used alone as a general evacuation signal (E2 application) for a building or area, or

• the audible evacuation signal component of a pre-recorded or system-generated voice message that is played in a building or area to signal general evacuation (E2 application), or

• the audible signal component of a pre-recorded or system-generated voice message that is played in a building or area to signal instructions to evacuate one area and relocate to another area of a building (ESRI application).

This Standard does not apply to audible signals that are applied for any use other than E2 or ESRI signals. This Standard does not apply to warning signals, to situations covered by national regulations for public disaster control, to alarm systems onboard ships, or to signals from all outdoor moving vehicles, such as police cars, fire engines, and ambulances.
