The different types of Audible Warning Signals

The different types of Audible Warning Signals

When choosing an audible warning signal for industrial purposes, there are some aspects you need to consider before choosing the correct signal.

Firstly, you need to consider what type of audible warning signal you require from a range of:

Electronic Sounders

In today’s world of technology, an electronic sounder is the most versatile product to use as this can be programmed to offer multiple tones and can be volume adjustable, making them suitable for almost every requirement. – – Sirens.

Sirens are a motor-powered device producing a unique sound due to its internal impeller.

Bells

Bells are suitable for daily signalling use that produces medium db output. Most commonly found in schools and workplaces to alert for lunch breaks.

Air Horns

Air horns are a good option for industrial & marine areas and hazardous areas. It is a non-electrical device with a high db output and low frequency, making it ideal for noisy environments.

Buzzers

This is an electro-mechanical type of warning signal in a robust housing. They produce medium-high db output with a low sound frequency

Hooters

Hooters are a motor-powered warning device with a horn. It has a high db output with low sound frequency, ideal for indoor and outdoor use.

You now need to take into consideration the sound level and frequency rating of your chosen alarm – this needs to be heard instantly and distinctly above any other noise in the area.

Next you need to consider the power consumption, electrical supply and IP rating of your chosen alarm and check with your engineer this will be suitable for your application.

Lastly you need to ensure you choose a quality product that will stand the test of time so to speak. By purchasing a quality product to begin with, it will save you time and money in the long run in maintenance, especially if the alarm is located in a hard to reach area.

Electronic Sounders

Electronic Sounders

Electronic sounders are commonly used in large buildings and businesses as an indicator; the sounder makes a loud noise when it’s triggered, either automatically or manually. These powerful devices are perfect for grabbing people’s attention during an emergency situation but are also ideal for many different applications from schools to factories.

Such situations are to alert a specific time – break time, lunch time etc, to alerting to emergency situations such as a fire, robbery, or evacuation purposes. These products are so versatile they are also regularly used for fault monitoring purposes to alert when there is a problem on a production line.

When sounders are used in conjunction with an alarm system, the component that acts as a hub is the control panel. Every unit incorporated into the system will use the panel as a medium of communication. Using the correct sensors, an automatic signal can trigger the electronic sounder to sound. The control hub also allows an engineer and user to monitor the system and check for faults or activation.

Sounders can vary in sound dispersion patterns and tone and can also incorporate LED’s to become a combined sounder beacon for applications where both light and sound are required for maximum impact.

Safety should always be a priority, it’s important to be vigilant and look out for different tools and devices that grab a person’s attention during an emergency situation quickly and effectively. A loud sounder and flashing light too in some places do just that.

Combined Beacon Sounders

Combined Sounder Beacons

It can often be difficult to hear an audible alarm if there is a lot of background noise. Similarly, it can be difficult to see a visual alarm in bright sunlight or if it is out of your line of sight.

A combined sounder beacon addresses these problems by giving both a visual and an audible warning at the same point.

There are many advantages to using a combined sounder beacon:

– Saves installation on 2 separate units.

– Allows for simpler wiring.

– Allows the installer to easily comply with Equality Act 2010.

For example, when fitting a unit in a disabled toilet.

– Allows the unit to act as a 2-stage alarm.

For example, a visual alarm only for a warning status, then a visual and audible alarm for an emergency status.

There are many different types of combined sounder beacons available to suit various applications from Tower Sounder Beacons to units where everything is inside a single enclosure.

At D G Controls, we offer a wide range of combined sounder beacons including LED, Xenon, 64 tone and Tower Sounder Beacons.

The benefits of Electronic Sounders

The benefits of Electronic Sounders

Ensuring safety in the workplace demands the use of different tools and devices. One very effective device is the electronic sounder, which is ideal for various applications, including factories and the manufacturing industry. It produces loud sounds to catch people’s attention when an emergency happens within the area. The device is closely similar to sirens, horns, and other audible alarms in responding as a warning.

What is an Electronic Sounder?

An electronic sounder is an audible warning device in place of visual beacons. It is best applied in noisy environments to provide caution effectively. This type of sounder is very versatile, thus sometimes more effective than a visual warning.

Each one is made up of durable housing materials, such as polycarbonate and plastic. They can be mounted in both outdoor and indoor applications.

Combined units are also available with clear or coloured LEDs for maximum usage. The sounder also features a single or multi-tone application. When combined, the device is known as a sounder beacon.

How Electronic Sounders Work?

Beacon and sounder devices can be found almost anywhere, as their uses also evolve in different applications.

Traffic Signalling

Warehouses can require more status signals to ensure protection in the workplace and to people surrounding the area. Site traffic is completed by a sounder to notify every one of the faults and other dangers.

Aviation Warning

To warn an aeroplane of tall buildings, the first solution could be a warning light. It makes obstacles more visible even from a distance. Adding a sounder is a wise decision to warn aircraft about possible hazards.  

Safekeeping

Having a warning device in the surrounding area increases safety. Therefore, placing a beacon or sounder outside the building is much better to easily alert the entire workplace.

Marine Warning

As said earlier, the electronic sounder is appropriate for many applications. Seafarers often depend on warning signals while travelling by water. A sounder helps to enhance their safety when in the ocean.

Evacuation Purposes

Evacuation areas need to be secured at all times. Electronic sounders work manually and automatically to deliver a warning signal. Thus, perfect for such an area protecting many people.
