Evacuation sirens are now being installed on all marked police vehicles around the country. The evacuation sirens are unlike any used by regular first responders in the U.S., the police said. They are nowadays European-style sirens. One of the reasons for the change was safety concerns about some American models. It also took time to get the new siren design and test it on various police vehicles to check its effectiveness.
In Europe, no laws are requiring that these sirens are visible, according to the police. Therefore, it is also important for agencies to decide what type of alarms to install, how many, and what kind of external warning lights to attach to the vehicle. In other words, they must decide what sort of system they want and then install it accordingly.
Evacuation sirens will be able to alert motorists as soon as a crisis has occurred. By sounding an audible tone, these devices will announce an emergency. Some may panic, and others may ignore the sound. For that reason, authorities need to make sure that everyone in a certain area knows where and when to seek help. There are three different types of audible tones for use with these devices: panic, emergency, and warning.
For instance, a hi-lo siren is available in Canada, Italy, Spain, and Japan and is similar to the American “holster horn” variety. The high-pitched “hi-lo siren” lets people know to evacuate safely and can be used to communicate directly with other responders. These kinds of evacuations often happen in areas where multiple emergencies are taking place.
High-pitched sirens are another audible warning method that uses a high-frequency sound wave to produce a loud sound and alert individuals of an emergency. Some types of high-pitched siren systems allow the user to select various voices and accents. Some modern siren models include a “hi-lo siren,” which can respond to a low-frequency voice command. A hi-lo siren can be useful for evacuations when law enforcement officials cannot arrive in time to help, and the siren may help alert individuals in the area to take action.
In addition to using different audible warning sounds, some manufacturers have introduced systems that incorporate computer technology into their siren systems. This technology allows these manufacturers to integrate emergency information and other important information to be included in the sound of the siren. This information includes graphics of weather-related conditions and the latest news.
