Attributes to look out for when purchasing Sirens
There is no dearth of sirens in the market. However, the most effective ones are those that have certain attributes that enhance their functionality. Purchasing such sirens will ensure complete value for the money you spend.
There are a wide variety of sirens available in the market, in all shapes, sizes and with all kinds of technology. For example you can get speakers which are about 9” in length and around 7” in diameter. The sirens should be reasonably compact for the sake of portability and it is possible to find a good system weighing less than 4kg. There are siren systems which can work with any kind of sweeping tone along with electronic and mechanical tones and High-Low sound patterns. Good siren systems should have the ability to produce tones that can penetrate high noise areas like crowded alleys or junctions, where the sirens have to be able to get the attention of everyone around. In fact, there are siren systems that produce low frequency tones synchronizing with primary siren tones for greater penetration.
You can also go for sirens which produce low frequency reverberations that can help in reaching out to drivers of other vehicles. These sirens are especially useful for ambulances and fire engines where you have to reach out to other vehicle drivers. These siren systems can help in alerting them to potential dangers whether it is on the highway or crowded streets, besides passing the message that vehicles ahead should pull off and make way for the emergency vehicle on a rescue mission.
sirens should be easily operable, which becomes an asset especially during emergencies. This is why the best systems come with simple push on and off buttons along with 7-position rotary switches for various functionalities. Advanced siren systems also come with hearing protection for the operators. Moreover, there are advanced timer mechanisms that can help in preventing the risks of overexposure. There should be a good level of control as well when it comes to reliable siren systems. The controls include noise cancellation mechanisms, volume control knobs, manual override buttons and external cancel controls for cancelling out tones through both positive and negative activation depending upon the requirement.
The controls provided with advanced sirens include tone duration selection through Scan-Lock features. You can also search for and then lock the requisite tone styles based on your requirement. In fact, the best siren systems can give you plenty of flexibility when it comes to setting the tone durations allowing you to set more than half a dozen tonal durations extending up to 60 seconds. Good siren systems come with multiple frequency bands which can be operated using a simple dip switch. Those operating the siren system will be able to select between quarter and half tones as well as a composite of both. Top quality siren systems give good switching combinations as well as the flexibility to mount anywhere, whether on roofs or grilles of vehicles or even on motor bikes. You should look for siren systems which have a truer quality of tone without compromising on the size. Compactness of sirens is a big asset as it helps in concealed installation and mounting flexibility, especially with wide range of mounting hardware options.
