Sounder beacon combinations are dual function warning devices. They integrate a beacon lamp and an audible sounder to form an audio visual alarm.
Sounder beacon combinations come with different tones incorporating high frequencies, low frequencies and industry-standard frequency patterns. They have different colour lenses to give an enhanced warning signal.
They also have a wide range of options for both indoor and outdoor applications. Some sounder beacon combinations are equipped with volume control and tuneable features.
Beacons may be constructed with halogen bulbs similar to those used in xenon flashtubes or LED floodlights.
Sounder beacon combinations are often used in emergency situations such as fire evacuations. You’ll find them in public areas and buildings such as:
Sounder beacon combinations can also be used for communication, such as the status of an airport by the rotational pattern or colour of the beacon.
They are also used in emergency vehicles such as police cars, fire engines and ambulances to attract the attention of other road users.
Typically, the audio range of a sounder beacon will be between 5 and 15 decibels above the ambient noise level.
There are many considerations when working out the coverage of a sounder beacon, for example, you’ll need to take into account any noise like the sound of people or machinery.
Although there’s no definitive minimum distance between two sounder beacons, you can calculate the distance required between two sounder beacons based on the distance the sound emitted travels
The decibel level of the beacon will be based on the person being one metre away from it. If you double the distance, so for example, are stood 2 metres away, the decibel level drops by 6.
DBI Control often use sounder beacons as a safety feature in our projects. In the photo below you can see a sounder beacon on top of a control panel which was part of a scrap conveyor system we completed in 2018.
