Most of these sirens are used along with flashing LED light bars in emergency vehicles which include highway patrol cars, fire engines and ambulances.
Police sirens are known for the quality of the speaker that is used in the equipment. The sleek looks and compactness add to the overall design and style element of the cop vans. Reliable performance is offered by these sires which come with highly compact amplifiers that are small in size but large in their functionality. The two most important attributes of these sirens is serviceability and portability. The portability is a function of the size and the performance that is offered within the limitations of that size. Serviceability involves easy maintenance and robust nature that allows tough usage at times.
Police sirens use several different attributes in order to enhance their performance especially in harsh conditions. Terminal block wiring and simple and easy to understand amplifier connections make them highly desirable for the industry. The amplifiers output can be controlled to get desired results depending upon the ambient noises. Sometimes these sirens are enhanced with 100W speakers to provide the right amount of volume.
