Go to: Previous Article Next Article
Police car sirens possess some exciting features which make them really useful during an emergency, when officials on an emergency vehicle need to get the attention of other motorists for several different reasons. Modern sirens have come a long way through the use of advanced technology to provide reliability and resilience in the face of some heavy duty usage. You can go for hands-free sirens which come with amplifiers that can easily be controlled by microprocessors. Rated at 100W or 200W, these sirens usually start off in standby mode and can be programmed to operate in a desired way.
The Police car sirens usually come with a Push To Talk switch, which can help you make use of a unidirectional microphone. This tends to override the siren tone and can be useful for addressing a larger group of people or motorists. Most siren functions are present on an illuminated switch panel with LED backlighting so that operating them becomes an absolute breeze. Some advanced siren systems come with LED lights that can help in diagnosis of the equipment even while the sirens are operating. Two important features of the siren system include radio repeat and public address and both these features can be operated in a hands free system without leaving the steering wheel.
There are a lot of options as far as siren tones are concerned. Some Police car sirens come with as many as 17 different Scan Lock tones, which can be scanned to pick the right tone for the situation. Good quality sirens come with 9-switch light control units along with power saving low current switching and special features like park-kill and time-out. In other words, you can kill the siren tone in order to avoid disturbing people in a park. Similarly it is easy to program a tone to play it for exactly a fixed amount of time. Remote dual siren amplifiers with control heads flush mounted and dual function sirens with removable microphones are also available for you to mount on emergency vehicles.
Some Police car sirens come with horn ring transfer switch along with combination On and Off buttons and frequency adjustment knobs. The frequency adjustment is important to make sure that the tone penetrates farther. Similarly, it is possible to adjust the decibel level as well with equal ease. Some high quality sirens also come with noise cancellation features that can help in making the tones sharper and clearer.
Police car sirens help in assisting emergency lights by attracting attention of those around, over and above the general noise present in high traffic areas. There are special light bars with sirens where the emergency light and sirens function together. The sirens which come with electronic parts that have been rigorously tested can be mounted easily inside or outside the vehicle. There are bail brackets, available for sirens for mounting at an adjustable height. Sirens also come with a quick disconnect plug which proves to be helpful when you want to dismantle them for repair and replacement.
