subject: Emergency Siren Equipment And The Features That Add To Its Utility [print this page] Emergency siren equipment could be a great addition to emergency vehicles proving greatly useful in emergencies. When there is a lot of ambient lighting, emergency lights could become slightly ineffective. In high traffic areas, siren sounds can prove to be very efficient in getting the attention of other motorists. In fact, the frequency or the pitch of the sound could even indicate to the severity of the situation. A wide variety of siren tones are provided as part of the equipment. These siren tones, such as manual wail, piercer, hi-low patterns, electromechanical tones and yelp are useful in different scenarios. The utility of the equipment also lies in the additional PA volume control and frequency control knobs that allow you to adjust the parameters.
Low frequency reverberating siren sounds for example, could be extremely useful for greater penetration across a larger distance. Siren equipment usually operates with 12V DC power supply, although 24V models are also available. Customers have a choice of speakers and amplifiers. Two 100 watt speakers can make sure that the siren doesn't lack anything in terms of the decibel level. Moreover, additional plug in microphones are also provided in sirens ensuring that their utility is enhanced four fold. Both, the microphone and radio repeat functions come with adjustable preset volume levels which can be altered if need be. Complementing the plug-in microphone is the push button which helps in overriding the siren tones and instead activating the public address system to announce important messages.
High class siren equipment not only has additional features like radio repeat, public address and hands-free operation control but also dip switches and bi-polarity activation. Horn ring transfer switch, slide button switch for controlling the siren sounds through Scan Lock mechanism and activation of siren tones through input are some of the other features that make the equipment extremely reliable. Polycarbonate and composite nylon are often preferred for the casing of the siren to make the equipment resilient to heavy duty usage. The backward compatible sirens are designed to adhere to California Title XIII as well as SAE requirements. They are well protected against reverse polarity and output short circuiting making them easy to install, service, repair or use.
Good quality siren equipment also has intuitive features like the howler which is an add-on over the existing siren tones. You can also automate the operation of some siren sounds for a specific time interval and also in a specific style of tone. Good reliable sirens come with LED indicators that can help in diagnosing the equipment in case of malfunctioning. Backlit switch panels can greatly enhance the ease of operation of the lights. A variety of mounting brackets for all kinds of surfaces are on offer too. Sirens are lightweight and compact which makes handling them very easy. The size of the speaker is usually less than 7 inches in length while the amplifiers are quite small too. Features like 10 second bursts at high frequency and flash pattern synchronization could make sirens even more useful.
