Police Sirens – Used By Almost All Law Enforcement

When paired with police lights, sirens alert drivers of an urgent need. Drivers will hear sirens before they see a police car fly by with lights on. Police sirens should be in in every police cruiser and undercover car too.

Purpose of Police Sirens

The purpose of police sirens is to alert a community that a cop is on their way to a call. By sounding their sirens, and activating lights, cops are asking for the right of way. When police have the right of way they can get to their call as fast as possible.

Police Sirens Have Changed Over Time

Today, most police cars are fitted with an electronic police siren. This type of siren simply plugs into a power source. When plugged in, an electronic police siren is able to create the same sounds a mechanical police siren makes. The benefit of an electronic police siren over old-fashioned sirens is ease of use. Mechanical sirens were made with many small parts and were hard to care for and use. Electronic sirens are easy to care for and turn on with the push of a button.

Police Sirens are Created for Law Enforcement

Police sirens, electronic and mechanical, are created for use by cops only. Every state in the US has statutes that outline who can use sirens in their cars. The improper use of a siren can result in jail time and fines. Other first responders; including firefighters, volunteer firefighters, and EMTs, may use sirens in their fleet vehicles.

Available Power Ranges and Volume of Police Sirens

Not all police sirens are the same. Not only are mechanical police sirens still available, but electronic police sirens can vary greatly from one manufacturer from another.

Have you ever noticed why some police sirens sound louder than fire truck or ambulance sirens? You probably have! You may be surprised to find out that many first responders use the same types of sirens. The reason some sirens sound louder than others is due to the way the gear is mounted.  Most emergency vehicle sirens create 110-120 decibels when turned on. Police sirens can sound louder than ambulances or fire trucks because cop cars usually have their siren mounted low on the bumper. Fire trucks also mount their sirens on the bumper, but the large size of fire trucks absorbs some of the sound. No matter what type of vehicle a siren is mounted on, the only way to control the volume is through the PA system.

Police Siren Speakers – How to Know Which Speakers are Compatible with a Police Siren


When purchasing police sirens or police speakers, you need to understand compatibility. Not all siren speakers and sirens will work together. The best way to make sure your gear will work together is to read the specifications. Gear that is not compatible could void your warranty and/or cause your siren or speaker to fail without notice. For instance, our Remote Police Siren runs on 100-watts, which makes it compatible with our 100-watt police siren speakers. Using a police siren and speaker together, which don’t match in wattage or specification will not be compatible.
