To direct the Comptroller General of the United States to issue a report on the effectiveness of local outdoor siren systems, and for other purposes.

In conducting the study under subsection (a), the Comptroller General shall—

(6) evaluate the efficacy of efforts by emergency management divisions to improve the precision of such systems;

(7) evaluate the efficacy of emergency management divisions, both in and upon, switching to systems that activate automatically upon the issuance of a relevant National Weather Service warning;

(8) evaluate the ability to connect such systems to the Integrated Public Alert and Warning System of the Federal Emergency Management Agency;

(9) evaluate the impact that different activation standards across the United States may have on the effectiveness of such systems;

(10) evaluate relevant cybersecurity protections for such systems; and

(11) evaluate whether improvements could be made to such systems and relevant procedures.

Not later than 18 months after the date of enactment of this Act, the Comptroller General shall submit to the Committee on Transportation and Infrastructure of the House of Representatives and the Committee on Homeland Security and Governmental Affairs of the Senate a report on the study conducted under subsection (a).
