A Comprehensive Guide to Audible Warning Signals

Click here for more information.

Audible warning signals can help to reduce incidents in a community and they allow people to become more aware of what is happening around them. Mostly, we can find this type of warning signal in places where there is a lot of traffic. They warn us of approaching hazards or dangers, allowing us to prepare better and react accordingly.

Audible warning signals play an important role in security and safety. By producing sound waves and noise, they provide an effective alarm or warning in all kinds of different situations. Sound allows us to hear, and communicate – this is why audible warning signal devices were designed to work alongside, or instead of, visual warning signals to increase safety.

Audible Warning Signals: Different Types & Usage

Electronic Sounders

This type of audible warning signal features a multi-tone selection as well as a volume control. This device emits sound waves and noises, designed to catch your attention even amid a huge crowd. Today, it is the most versatile type of audible warning device in terms of security measures.

Electronic sounders are primarily utilized in noisy places and in places where an audible warning is better than a visual. They are also commonly used as a fundamental part of a system by being linked to an alarm circuit.

Alarm Hooters and Bells

An alarm hooter is a type of audible warning device that makes an audible alarm to evacuate or alert people. Dual-tone hooters are most commonly used in fire alarm systems to determine fire alarms over faulty audible alarms. On the other hand, bells are known to be used as time indicator in schools as well as factories.

Sirens and Air Horns

For situations needing an extremely loud noise for signalling, air horns and sirens are designed to play that role. These were commonly found on emergency vehicles that help to clear the roadway from vehicles and people. They are also applicable in places where the noise has to cover a wide range. Today, you can find motor driven sirens, hand-cranked sirens, and so much more.

Buzzers

Buzzers or beepers have three varieties, including piezoelectric, mechanical, and electromechanical. This type of audio warning signal device is usually mounted on a ceiling or wall – it uses very little power, whilst producing a very loud noise.

Things To Consider When Installing Audible Warning Signals

Before installing an audible warning signal, it’s essential to check that all factors have been considered:

Sound Level & Frequency Rating – Sound level is the alarms amplitude of air pressure. On the other hand, the frequency rating is the pitch of sound or the number of different pressure per seconds.

Structure Quality – Make sure to choose high-quality audible alarm to get the most of your investment.

Power Consumption – Something to check to ensure compatibility with your intended power supply.

Quality Testing – An audible warning signal needs to be tested under different kinds of testing. It includes reverse voltage, surge voltage, shock/ vibration. Water spray (IP Rating, and so much more).

Generally, audible warning signals come with informative purposes and they help in increasing safety. As well as being low maintenance, they also allow people to avoid accidents by acting as preventive protection for the community.
