subject: Emergency Sirens And Lights And How They Benefit From Modern Technology [print this page] Emergency sirens and lights are extremely important for an emergency vehicle considering that there needs to be a mechanism using which the crew can attract the attention of motorists on the road. Emergency vehicles plying on the road might need a freeway to rush to the site of the crisis such as medical ambulances or fire engines. Similarly, they might need to alert other vehicle drivers to maintain a safe distance such as heavy equipment or inflammable material carriers. They might also need to draw the attention of motorists on the road to an impending danger such as a patrol car warning of oil spillage, construction, road repair and wreckage sites. Siren police vehicles use, will also help in sending out a warning signal to other interceptors.
Technology helps in making the sirens and lights used by emergency vehicles extremely efficient. This is obvious from the fact that modern siren police vehicles use, and emergency light bars mounted on roofs of vehicles are far more efficient and effective. The light bars that make use of LEDs for example, can provide excellent control over a wide array of features. Gen III LEDs using total internal reflection technology and light house optics ensure that the beams have a wide and penetrative coverage. Besides, these lights provide excellent controls through a control module so that individual parameters can easily be controlled. For example, the beam angle of emergency lights, the decibel levels of the siren and the frequency can all be easily controlled using different kinds of knobs provided on illuminated switch panels.
A great thing about modern sirens and lights is that they provide lot of flexibility in terms of how you mount them. Strobes can be installed through small mounting holes and still provide intensely bright lighting. The dash and deck lights are compact and yet highly efficient. Lastly, the lights can even be synchronized with each other to create an even more powerful warning signal. Another impressive technology is the built in flash patterns with Scan Lock mechanism to browse through the patterns and lock the desired one for a given situation. The same mechanism can actually be used for siren tones as well, to explore and then lock a particular siren tone. The use of lenses and filters can further enhance the lighting, while the siren police vehicles use comes with integrated radio repeat and public address systems as well.
A very interesting use of technology in modern sirens and lights is in the design of the chassis, which is robust and rugged and yet lightweight too. The siren police vehicles use can be mounted in a variety of positions and still offer excellent service. You can adjust the height and orientation of the mount as well to cater to your requirements. There are diagnosis indicators in sirens too. Emergency lights make use of a wide variety of switches to make operation extremely easy, given that they collate so many different types of lights and lighting features including synchronization with sirens.
