5 Core Components of Police Siren Systems

The 5 core components of a police siren system used in law enforcement vehicles include the siren amplifier, speakers, control head or interface, PA systems and tone options. To further elaborate on these components, D&R Electronics Co. Ltd., a leading fleet vehicle solutions provider based out of Bolton, Ontario, explores its purpose and features in this blog.

What Are The Major Components Of Police Siren Systems?

Siren Amplifier

The siren amplifier is responsible for converting low-level signals from the control unit into powerful sound waves. The tone emanated by the amplifier can be modified automatically or manually, depending on different law enforcement functions. 

Speakers

Speakers are the components that transmit the sound emitted by the amplifier over long distances. Speakers are generally mounted on the grille or bumper of a police cruiser. Two key factors to consider during speaker selection include wattage and impedance. The former determines how well a speaker can handle power, and the latter determines the amount of power flowing through them. 

Control Head or Interface

The control head or interface is an integral part of the modern police siren system. It comprises integrated controls for operating the siren and the emergency lighting system. 

PA System

Police car siren systems also double as public address systems in many police vehicles. It enables law enforcement personnel to directly address other motorists or to control traffic via verbal commands. 

Tone Options

Police car sirens have different tones or options, each serving a unique purpose. They include the Yelp, Wail, Hi-Lo, Thunder, and Stinger. Some are high-pitched to grab immediate attention, whereas some emit low frequency to demand attention even in high noise and traffic areas.
