A reliable police siren can be greatly helpful at the time of an emergency when you need to get the attention of other vehicles on a noisy day. The siren can reach the attention of those who are unable to see the flashing light bars of your emergency vehicle. The sirens prove to be very useful with an array of features. One of the important aspects of a good siren is a large number of siren tones including wail, yelp, phaser and air horn. Some of these tones are horn ring adaptable too.

An advanced police siren can come with as many as 8 different operational modes. The siren systems usually come with intersection mode which helps in alternating the different siren tones. This provides variety when required. These siren tones are loud and clear enough to be perceived even from a great distance. For a speeding law enforcement vehicle it is important that vehicles ahead of it take notice and give a free path. It should be easy enough to operate these siren tones as that will make them more effective. This is the reason hands free operation is available with a good siren system as that will allow one to operate ...

The housing of the police siren systems is quite rugged. It is made tough to withstand years of heavy duty usage which can be expected for sirens mounted on emergency vehicles, unlike in case of sirens used for burglar alarm systems in hospitals, banks or even private houses. This is why rugged powder coated steel housing or aluminum housing is used for siren systems to lend reliability and structural sturdiness. The construction of the sirens is such that it can be used both for internal as well as external mounting. Moreover, the sirens are vibration, corrosion and moisture resistant which extends their longevity to a good degree.

An advanced police siren comes with an illuminated faceplate or switch panel with an array of switches serving different purposes. This includes rotary switches or slide position switches which can be used for tone or mode selection. There are special knobs in the front for control of the frequency or tone decibel value. There are push button switches for intersection modes and on/off functions as well. High quality sirens can be remotely operated as well for additional operational ease.

When you go for a high quality police siren you have to pay attention to the speakers and amplifier available. 12V 100W sirens will be useful enough for most purposes, with peak currents below 10 Amperes in most cases. Dimensionally compact sirens are usually less than 2 – 3 inches deep. Hard wired, noise cancelling microphones are also present in the sirens for those who need additional features apart from the basic package of siren tones. Full featured dash mount sirens have noise cancellation features for additional clarity. They come with bail brackets and adjustable height swivel brackets for mounting ease as well.
