Features That Make Police Sirens So Effective

Police sirens prove to be effective in those situations when flashy lighting cannot prove to be of much use. Also, the sirens can combine with the emergency vehicle lights to create a powerful cautionary weapon that can sail across traffic and through darkness to reach other motorists. Sirens can be very useful in critical situations where there is too much chaos and you need a loud and clear signal to go out. The sirens usually have an array of built in siren tones which can be used in specific scenarios.

A very interesting design aspect of Police sirens is that there is a default selection available along with a manual override button. So, while you can use Scan Lock mechanisms to flip through different siren tones and lock the one you want to be operated, you can still go back to the default one in no time by using the manual override. This comes handy during high crisis situations where you want a particular signal to go out. Similarly you can use this as a cautionary tone that can be interpreted by other party waiting or anticipating for the signal.

Basic Police sirens come with 200 Watt output speakers and sometimes an additional amplifier too. These speakers can ensure that the siren tone is loud and audible. There are volume control knobs available too. Good quality sirens also come with noise cancellation microphones and add-on systems like the public address. These additional features could prove to be really useful during emergencies especially when there needs to be a declaration of caution. The most common tones built into sirens include yelp, phaser, manual wail and Hi-Lo. There is a hold feature present in some sirens, while it is also possible to vary the frequency of the tones depending upon the requirement.

Advanced Police sirens come with well secured circuits where there are monitoring systems in place to detect voltage spikes. Apart from high voltage issues, the systems are built to tackle reverse polarity and short circuits as well, so that they dont pose threat to those plying the emergency vehicles. In fact, some siren systems come with special diagnostic elements too. For example, you could check whether there is short circuit or some other problem based on a glowing LED indicator which makes repair and detection of problems very easy.

Police sirens also come with other intuitive features like horn transfer and park kill, which are important for vehicles that are used within cities often. Timed output feature is another one that makes automated operation easy. It also proves useful during tough times. Good sirens come with hands-free equipment which allows the same person driving the vehicle to operate the siren, especially if there is a shortage of personnel. The efficiency of the control head has increased to a great extent over the years. Moreover, some sirens come with customized mounting brackets for special vehicles like Tahoe and Crown Victoria. Low frequency tones are also present in advanced sirens for their penetrative abilities.
