Emergency sirens prove to be the right combination along with emergency flashy lighting to get the attention of motorists on the road. Sirens can help convey a warning signal and its severity. They can also help in reaching out to distant vehicles especially during a jam or when it is peak traffic time. Emergency vehicles such as ambulances and fire engines would need sirens to help them get a clear path for speeding along. Sirens with full size speakers and amplifiers with wattage of over 100 can be really effective in chaotic and noisy surroundings.

Emergency sirens can prove to be useful if they have mounting hardware that can help in installing the equipment externally or internally. Sirens should therefore be moisture resistant as that would help in using them during adverse weather conditions. ABS or composite nylon housings are commonly preferred for compact sirens to protect them from moisture as well as from high degree of vibration. Effective sirens tend to provide a lot of extra features that come good during emergencies. For example, hands free control could be useful when a vehicle is short ...

The installation package of Emergency sirens also consists of pigtail connectors, mounting clamps and straps and shielded power cords. Some sirens come pre-wired with a quick disconnect plug which makes it easy to turn the power on and off. The hardware also includes illuminated switch panels and control knobs. There is a volume control knob to adjust the decibel level of the siren, while there are separate knobs for tone clarity and frequency of the siren. The siren tones usually available include air horn, yelp, piercers, Hi-Low tones, manual wail tones, etc. One can also set default siren tones which can be turned on with a manual override push button during specific scenarios, to convey special warning signals. Otherwise, Scan Lock mechanisms help in easily scanning and selecting the desired siren tone to be played. Good quality sirens also come with replacement warranty along with warranty for service and sometimes upgrade.

Emergency sirens need to be compact, as that makes them portable and lightweight. Commonly used siren units are around 2 – 3 inches in height and around 5 – 6 inches in length and width, weighing less than 3 lbs. This makes them likely candidates for magnetic mounting as well. Universal mounting brackets are provided with the kit in some cases ensuring that the same siren unit can be switched across multiple vehicles whenever required. The compact size of the siren tones presents the additional advantage of concealed installation. This suits unmarked vehicles, which might need a means to send out a warning signal but at the same time would want the equipment to be virtually undetectable. Compact sirens can be installed with ease near the front grille or on the roof of the vehicle, well secured against voltage spikes or short circuiting issues.
