Electronic Siren Sounds Explained

Posted by on Aug 24, 2015 in Sirens | 0 comments

If you think all police, fire, and EMS use the same siren sounds, you’d be wrong. First responders have several siren sounds choices at their disposal when they choose an electronic siren. Below, we will go over the five most popular siren types and descriptions of the sounds.


The most popular siren sound is the wail. The wailing sound is available on just about any siren you can buy on the market today. If you’ve ever seen an episode of Dragnet, you know exactly what the wail sounds like. It has a sharp pitch that rises and falls. When the wail siren sound was first created, the highs and lows were associated with the speed of a vehicle. Today, these sounds are recreated by an electronic siren.


The second most famous siren sound is the yelp. Like the wail, yelp sounds are offered on just about any siren on the market today. The yelp’s pitch changes rapidly. Many first responders opt to use the yelping sound because it conveys a message of urgency.


Hi-lo siren sounds aren’t as popular as the wail and yelp in the US but are still very effective. The hi-lo sound is European-inspired. Most sirens that offer hi-lo tones also intersperse whoops and other noises for the best effect.


If you’ve ever heard a first responder using a Phaser siren you probably wouldn’t forget it. Some retailers refer to the phaser as the piercer. The phaser sound has an intergalactic ring to it. Despite its odd sound, many first responders rely on the Phaser siren to move traffic because it is hard to ignore on the road.

Air Horn

First responders have used air horn sounds for generations. Today the air horn siren sounds created by electronic sirens are electronic reproductions of an actual air horn. Unlike the four siren sounds mentioned above, first responders don’t usually use the air horn siren sound while driving. Instead, this sound is normally reserved for getting the attention of someone in particular. For instance, a car that isn’t moving over for lights or a crowd that is blocking an ambulances’ path.

The IW3 100-watt siren from 911 Signal USA can create all of the familiar siren sounds mentioned above and more. In addition to the wail, yelp, phaser, hi-lo, and electronic air horn sounds, the IW3 can create whoop, manual, and warble sounds.

Paramedics Urge Drivers to Move to the Right

Posted by on Sep 20, 2014 in Sirens | 0 comments

Paramedics in Dubuque County, Iowa, are speaking out about the dangers of civilian drivers ignoring emergency vehicle lights and sirens. Paramedics in this county are doing this in hopes that more drivers will move to the right when they see ambulance lights flashing in the distance.

Paramedic Says Fewer Drivers are Moving Over for Ambulance Lights

Dani Balk, a Dubuque County, Iowa, paramedic has been in EMS for over a decade. According to Balk, in recent years, fewer drivers are moving to the right when ambulance lights are popped on. In addition to being dangerous to everyone on the road, Balk adds that it is extremely frustrating when drivers won’t clear a path for emergency vehicles. Balk goes on to say that she believes many Iowa drivers don’t pull over for ambulances because they simply don’t hear the sirens or notice the flashing emergency vehicle lights. Marvin Ney, the director of Paramount Ambulance in Dubuque shares Balk’s frustration and goes on to say that they need everyone in the community to help them get their jobs done.

Iowa’s Move Over or Slow Down Law

Iowa has a Move Over or Slow Down law that requires drivers to yield the right of way to any emergency vehicle that is flashing lights or delivering an audible signal. According to this law, when drivers see or hear an ambulance or other emergency vehicle, they are legally required to move to the right and then stop and wait until the vehicle has passed before proceeding.

When you See Lights, Move to the Right, and Everything Will be Alright

Marvin Ney is so determined to urge more drivers to the right in his community that he has paid to have commercials created to support Iowa’s Move Over Law. Ney wants drivers to remember the jingle “you see the lights, you move to the right, and it will be all right.”

Iowa Police Officer Stuck by Intoxicated Woman

Posted by on Jun 10, 2014 in Latest News, Police lights, Sirens | 0 comments

On June 8, 2014, Officer Nick Swanson, an Iowa officer, was working to clear cattle from an interstate and was rear-ended by a Nevada woman. Officer Swanson had his emergency lights activated and was driving slowly when the collision occurred. Swanson received minor injuries, but is expected to recover fully. The unidentified Nevada woman was arrested for OWI (operating a motor vehicle while intoxicated.)

Iowa Officer Received Minor Injuries, but not all Police are as Lucky

Thankfully, in this collision, Officer Swanson only received minor injuries. Unfortunately, not all officers involved in motor vehicle accidents on the road do as well. According to Police Chief magazine, 700 officers were killed from 2000 to 2009 as the result of car accidents or motor cycle accidents. Some of these deaths were a result of an officer standing outside the vehicle when the accident occurred.

Police Regularly Put Themselves in Danger

Police officers regularly put themselves in danger. Whether racing to a burglary in progress or stopping a speeder on the side of the road, police must use caution. This is especially true when cops have to drive slowly on busy roads or park on the sides of roads where other drivers may not immediately see them. One of the best ways law enforcement officers can help keep themselves safer is by outfitting their fleet vehicles with high-quality LED lights. LED emergency lights provide visibility that improves their safety on the road.

EMS Depts in Chicago are getting more Personnel and Ambulance Upgrades

Posted by on Apr 17, 2014 in Sirens | 0 comments

As experts in the emergency vehicle light and equipment industry, we understand how important it is for departments to deal with budget cuts and decreased manpower. Budget cuts and staff cuts are needed because of decreased tax revenues and an overall weak economy. However, in Chicago, recent controversy has encouraged the city to upgrade their ambulance fleet and refuse to sit idly by while their EMS department is cut back. In fact, Chicago is getting more paramedics on duty and is upgrading aging ambulances.

Chicago EMS was not Meeting State Requirements

Chicago’s decision to upgrade and hire paramedics was a direct result of an investigation by CBS Chicago. In this investigation, CBS Chicago determined that Chicago EMS was not meeting state guidelines for response times. The reports of the investigation were released on February 6, 2014, and the report stated that some Chicago patients were waiting for up to thirty minutes for an ambulance to respond. On the other hand, the Chicago fire trucks were able to respond to the same scenes within a few minutes. ambulance en route to emergency with fire blazing in the background

In addition to more paramedics at hand, the City of Chicago will also add 15 more ambulances, which will increase their fleet from 60 to 75.
