Emergency Vehicle Sirens

J1849
This SAE Recommended Practice provides laboratory test procedures, requirements and guidelines for electronic siren systems with a single loudspeaker, and electromechanical sirens for use on authorized emergency vehicles, which call for the right-of-way. This document is applicable only to such sirens that have all dimensions across the sound-emitting opening equal to or less than 0.5 m. Test procedures and performance requirements for individual system components are not included in this version. Data obtained from measurements of siren performance depend not only on the characteristics of the siren tested, but additionally on the test procedures and the characteristics of the measurement instrumentation and test environment. These additional factors must be well defined and controlled to obtain reliable data.

This SAE Recommended Practice provides laboratory test procedures, requirements and guidelines for electronic siren systems with a single loudspeaker, and electromechanical sirens for use on authorized emergency vehicles, which call for the right-of-way. Test procedures and performance requirements for individual system components are not included in this version. Results obtained for a siren system with a speaker array that is greater than 0.5 m in any dimension shall apply to the system only when the array is in the same spatial configuration as tested (i.e., the same speaker separation and orientation).
