All Weather Police Sirens for Emergency Vehicles
Police sirens are extremely useful accessories in cop cars. However, they are equally important in emergency vehicles because these sirens help these vehicles navigate through heavy traffic with ease and reach the point of incidence at the earliest to save lives and prevent damage to property.
Weatherproof police sirens complement high quality emergency lighting to make sure everyone around is made aware of the presence of an emergency vehicle. Whether it is an ambulance rushing to the hospital or a fire rescue vehicle rushing to a crisis site, a patrol car that needs help or a law enforcement vehicle that needs a free way, the sirens can prove helpful to reach those who cannot spot the lights. Sirens tend to be effective amidst chaos and traffic and in areas where emergency lighting proves to be of no use. The sirens ensure that those driving ahead of an emergency vehicle understand that they need to pull away letting the vehicle pass by.
police sirens come as a combination of siren and speaker, with more than half dozen built in siren tones including yelp, manual wail, air horn, piercer and hi-lo tones. More than the variety of tones, the control over the sound is important, which is why advanced sirens have special knobs that allow you to vary the frequency and volume and adjust them at an optimum level. High-power electronic sirens can provide superior performance in all kinds of conditions. Modern sirens come with built in amplifier and microphone too, providing more features that would come handy during a crisis. The 100-watt amplifier can help magnify the sound produced by the electronic siren. Tonal quality can be changed easily with special controls and one can also choose between higher and wider frequency ranges, depending on the desired pitch.
The police sirens provide additional features like hands-free control which makes operating the siren easy. Scan Lock siren tones can be easily selected and locked. An interesting feature is the presence of a default tone and a manual override switch which can allow you to play the default tone during emergency. There is a special public address system in some sirens too, that allows traffic control and law enforcement officials to address those around and get heard over the surrounding din. Advanced sirens also have special PA volume control and a knob for noise cancellation which helps in maintaining tonal clarity.
police sirens come with special rotary switches as well to easily switch between Scan Lock siren tones and manual tones. The sirens are very easy to install without really driving holes into the vehicle surface or removing the front grille completely. They can be pre-wired with a quick disconnect plug that helps in easily replacing them or servicing them if required. Modern sirens are long lasting and durable, owing to the sturdy casing that is resilient to vibration and heavy duty handling. The sirens also come with special LED indicators which prove to be useful for diagnosis whenever there is a problem with the performance of the siren. The compact sirens with black nylon or composite casings are hardly heavier than 2 – 3 lbs and can deliver a very loud, traffic clearing warning if required. They are also designed as per standard certifications making them highly reliable in the face of adversity.
