摘要：A preferred siren including a base having a central axis and a peripheral wallcircumscribed about the central axis to define an internal chamber. The peripheral wallincludes a plurality of apertures in communication with the internal chamber. A rotor isdisposed within the chamber and centrally aligned with the axis. The rotor includes aplurality of spaced apart fins radially disposed about the axis, each of the plurality of finshaving an outermost portion at a peripheral edge of the rotor and an innermost portionlocated between the axis and the peripheral edge. An external housing cooperates withthe base to enclose the rotor within the internal chamber, the external housing includinga first plurality of ports and a second plurality of ports, the first and second plurality ofports being in fluid communication with the internal chamber of the base. A driver iscoupled to the rotor and is powered by a supply of carbon-dioxide gas to rotate therotor about the axis at a rotational speed such that external air is drawn through the firstplurality of ports, into the chamber and out the second plurality of ports so as togenerate an alarm sound having an intensity greater than 100 decibels (100 dB).
