Types of sounder and beacon

Traditionally, the choice of sounder and beacon was rather easy, but with modern markets expanding and with more needs and preferences of consumers being considered, there are several types one can choose from. For example, here are some of the more popular configurations based on operational settings and space constraints.

Combined Sounder/Beacon Units

Many industries and applications require devices that can perform more than just one function. This requirement leads to the development of combined sounder/beacon units, which integrate auditory and visual signaling. They are more efficient and therefore preferred by companies operating in spaces that have very high ambient noise levels. It is also possible to find these all-in-one systems in emergency signaling and notification topology.

Intrinsically Safe Beacons

These types of beacons are used in industries that involve highly explosive substances, such as oil and gas or mining companies. Beacons that are intrinsically safe are manufactured according to engineering safety standards that limit their electrical and thermal energy output. Because of this, they cannot ignite flammable substances such as gases, dust or liquids. Many of these beacons frequently also incorporate sounders, further enhancing their safety features.

Permanent vs. Portable Beacons

The beacons can be broadly classified into two categories based on their mounting and deployment flexibility. While permanent beacons are installed in fixed positions, usually in places where, for example, emergency exits or alerts must be expected, portable sounder and flashers can be relocated depending on the situation. Portable beacons are ideal for industries that incorporate temporary worksites and need to be constantly mobile, such as construction work.

Solar-Powered Beacons

Solar-powered beacons provide green energy means of operation. They are particularly suitable for remote locations where power installation is not possible and for those areas where electricity is most likely to fail.

Applications of sounder and beacon

The devices are employed across many industries because their requirements for safety, communication and operational efficiency need some form of signaling system. For example, here are some common applications of sounders and beacons.

Industrial Facilities

Sounders and beacons are primarily used in industrial spaces such as factories, power plants and refineries to assist in alerting workers about the various hazardous conditions such as equipment failures, toxic gas leakage and evacuation instructions. This is why many of these devices are fitted with very high decibel sound output and visibilities strobing LEDs to get across emergency messages effectively in such extremely noisy working conditions.

Construction Sites

Like most dynamic environments, construction sites require a lot of mobility and, hence, the use of beacons and sounders. These devices are usually used to alert workers of any impending dangers such as machinery traffic and are also used for safety notification purposes, such as when there is an imminent evacuation. The portable sounders and beacons are fixed on temporary structures and even on personnel protective equipment to ensure their message transmission capability at all times.

Mining Operations

Due to the very hazardous nature of work underground and sometimes even above ground, mining operations require signaling devices that have very high reliability and safety. For these reasons, only intrinsically safe beacons and sounders are deployed in underground mining or even in any area where there is a possibility of explosion. These devices signal evacuation, equipment failure and any other emergency effectively.

Maritime and Offshore

Oil and gas drilling, shipping and other marine industries rely on the use of waterproof and rugged beacons and sounders for security purposes. These devices are normally mounted on offshore platforms, ships and buoys to notify personnel of hazardous weather conditions, approaching vessels and evacuation procedures. The predominantly strobe light visibility and multi-tone sound output ensure messages are delivered clearly in ambient conditions.

Emergency Services

Speaking of emergency services, beacons and sounders are crucial devices in ambulances, fire engines and police cars. They use these devices to provide people with a clear indication that they are approaching for the way to be cleared and also to get across important communications to the other emergency response operators.

Product specifications and features of sounder and beacon

The primary function and objective of sounders and beacons is to get across aural and visual signals. Even though other specifications are incredibly different from one device to another, they, however, share several common factors regarding features. These include:

Sound Output Levels

The sound output levels refer to the sound that a sounder can produce, which is measured in decibels. Decibels are merely the unit of measurement of sound level, and their higher values mean that the sound will be deafening. Please note that the required sound output will solely depend on the background noise of that area where the device is installed. For instance, industrial and construction areas require sounders with high decibel levels because they cannot hear them if they do due to all the noise. However, for typical office environments, sounders with a lower sound output level are preferred.

Flash Energy and Frequency

This refers to how bright and fast the beacon's light generally is. Measured in Joules, the flash energy for the LED beacons is usually high because they are power efficient and thus come with a longer life span. The flash frequency, usually expressed in Hertz, indicates how often the beacon will flash per second. Higher frequencies are much more effective for attention-seeking purposes in an emergency.

Color

The color of the beacon light also affects its visibility and meaning. The different colors are usually applied based on the various signaling needs. For example, red beacons are generally used for alarm purposes, while green ones are used to indicate normal situations. Blue and amber colors are mostly used within industries to indicate work in progress.

Ingress Protection (IP) Rating

As earlier mentioned, sounders and beacons are meant to be used outside even in extreme environmental conditions. The IP ratings are waterproof and dustproof based on two digits, such that the first indicates protection against solid execution, while the second says about water. Only devices with an IP rating of at least 55 should be considered for deployment outdoors in the element.

Power Supply

Beacons and sounders can come with primary power supplies and backup batteries in case main power sources fail. These include the ones powered directly from AC/DC power sources, while others use rechargeable batteries from solar power to electric grids – mostly portable beacons. The efficiency of a power supply ensures that the device works continuously even during outages, particularly in emergencies.

How to Choose the sounder and beacon

Here are some important factors to consider, which can help make the right decision.

Operational Requirements

What is the primary purpose of the need for sounders and beacons? Should they provide general signals for intra operations, or should they mean life-threatening alarms? The operational questions like these will determine whether one will need a simple general sounder or a combined sounder and strobe light and which features will be crucial. For instance, industrial facilities require systems with a much higher sound output level and greater flash frequencies due to ambient conditions compared to office spaces.

Environment Conditions

Both sounders and beacons should be adequately protected against environmental conditions: waterproof, dustproof and with adequate IP ratings. It is also essential to consider whether the device will be outdoors, as weather changes will affect the sea and color. Beacons and sounders for outdoor application use have higher IP ratings and are made of more robust materials.

Compliance and Standards

One should consider the regulatory and industry standards which apply to the use of sounders and beacons in their different operational environments. Warranty certifications and approvals from recognized agencies are manufactured based on different local and international rules. They ensure at least a minimum standard for security and have features such as being IS for oil and gas or having low-frequency horns for good hearing protection. Ensure the decision maker device's compliance with necessary standards to avoid future legal problems.

Ease of Installation and Maintenance

The operating cost of maintaining and installing for the sounders and beacons will always be a concern for many. Devices that are easy to install and reconfigure and those that require low maintenance should be preferred. These factors include whether certain models allow for easy replacement of parts such as batteries or even firmware updates without taking much time or resources.

Budget Considerations

Therefore, two major factors that the decision on which sounders and beacons to go for includes are interrelated: operational requirements and cost. However, to choose the more affordable solutions, one should ensure that the budget can at least cater to the minimum needs regarding the operation environment's needs and compliance requirements.
