The police sirens available now are unlike the ones that were available in the past. Thanks to the advancements in the field of science and technology, the sirens today have many more features than they did in the past and are very useful.

Police sirens provide ideal foil to emergency lighting, reaching even those motorists who are too far in front to actually perceive the lighting. What makes these sirens so useful is that they are compact and easily installable and are ideal in chaotic situations where you want to send a warning signal to motorists all around. Sirens come with 100 or 150Watt amplifiers which provide a high decibel tone perfect for noisy areas. The compact sirens come with 8 – 12 independent siren tones including wail, yelp, manual, air horn and Hi-Lo tones, each of which can be easily selected using pattern selection switches provided along with the sirens. In some cases, 6 position or 7-position slide or rotary switches are used for easily varying the tones whenever required.

An interesting aspect of Police sirens is that they come with a separate manual override button. By pushing the button it is possible to select a default tone whenever required in special circumstances, especially when a very specific signal has to be sent across. Siren panels come with LED backlighting which helps in spotting the various buttons and operating them easily even in the dark. LED lighting is also used for diagnosis indicators which are in place to convey information about the status of the sirens. For example, there are special indicators which can blink when there is short circuiting.

Police sirens come with special noise cancelling microphones as well which ensure that the tones have an excellent clarity about them. This proves to be useful when highly penetrative sound is required in high traffic areas, where noisy, unclear sirens could easily be drowned out by other noises like car horns. The sirens are also provided with volume control knobs which will allow you to adjust the decibel level to suit the situation. There are also control knobs to vary the pitch of the tone which too can be adjusted with high pitched tones, reserved for severe crisis situations.

Police sirens are provided with ample protection against short circuiting and high voltage spikes. This not only ensures longevity for the sirens but also makes them safer to use. One can also go for DIP switch programmable siren systems with mounting brackets and reverse polarity protection system, along with hands free tone control for easily operating them.

Police sirens come with hassle free 5 year warranty which provides plenty of assurance to the users. There are push button switches for easily turning the lights on or off to complement the rotary switches. Two way L-mounting brackets are used as well with sirens and so are universal mounting brackets which come handy especially when the sirens are used with several different vehicles. The housing is made of black nylon or rugged aluminum which provides resistance from moisture, vibration and corrosion.
