Essential for the proper operating of machines and processes, automation signaling includes beacons and sounders such as sirens that send automated signals or alert operators to the current status of a machine process. The various signaling systems are often a requirement for compliance in workplaces or public areas, wherever machinery or equipment might pose a hazard to personnel.
From emergency lighting to warning buzzers, automated signals cover a wide range of workplace and equipment applications. Its primary purpose is to make sure the user or personnel in the work environment are able to easily discern the operating state of electromechanical machinery, improving efficiency and ensuring workplace safety. Components such as signaling towers are used in automation and control processes as a quick, visual verification of stop, start, or if there is a fault in operation.
Ensure you're keeping your workforce safe with our extensive range of sounders and beacons for use in numerous commercial and industrial sectors, including construction, automotive and aviation.
Types of Sounders and Beacons
- Rotating Beacons: Rotating beacons contain a continuously lit bulb that rotates to give the effect of a flash, which is ideal for attracting attention to moving vehicles or urgent machinery processes. Industries such as construction, mining, and logistics often use these warning lights to signal moving heavy-duty machinery, cranes, or construction vehicles.
- Flashing Beacons: These beacons have a bulb that flashes on and off, offering the same advantages and purposes as a rotating beacon. This type of warning light is used to alert personnel to potential hazards or critical alerts. Thus, they are widely used in manufacturing plants, industrial warehouses, and airports where clear, attention-grabbing signals are necessary to manage busy environments.
- Flashing Strobe Beacons: Flashing strobe beacons produce fast, regular flashes of light, which may be advantageous in low light or outdoor conditions. The intense, high-frequency light they produce can penetrate fog, rain, and other visual obstructions, making them ideal for emergency vehicles, outdoor construction sites, and traffic management systems.
Importance of Bulb Types in Beacons
The bulbs used in beacon lights can vary depending on whether you choose a halogen beacon, Xenon beacon or LED beacon. Each bulb type has differing advantages for visibility, longevity and energy efficiency, as discussed below:
- Halogen Bulbs: Halogen beacons provide a bright, consistent light that can be highly visible in various conditions. However, halogen bulbs tend to have a shorter lifespan and higher energy consumption compared to other types. This can result in more frequent replacements and higher operational costs.
- Xenon Bulbs: Xenon beacons offer intense and highly visible light, which is particularly effective in sending warnings even from a distance. While Xenon beacons provide superior visibility in industrial environments, they are less energy-efficient than LEDs and have a shorter operational life.
- LED Bulbs: LED beacons are the most energy-efficient and long-lasting option available to power safety devices. They provide a bright, clear signal that remains highly visible even in challenging conditions, including low light or outdoor environments. LED bulbs, just like LED tube lights, consume significantly less power and have a much longer lifespan compared to halogen and Xenon bulbs.
Applications of Sounders and Beacons in Industry
Applications of electronic sounders and beacons are diverse, covering safety measures, operational alerts, and emergency responses. Here’s a closer look at their usage:
1. Emergency Systems
- Fire and security alarms: In emergency situations, beacons and sounders are essential for safety. They are used in fire and security alarms to deliver clear, unmistakable signals about potential dangers. A well-placed light can immediately grab attention, ensuring that personnel are aware of emergencies and can respond swiftly.
2. Traffic and Machinery Alert
- Internal traffic systems: In warehouses, where internal traffic management is crucial, beacons and sounders help prevent accidents involving machinery such as forklifts. A safety light mounted on a forklift can signal other workers to its presence, reducing the risk of collisions. Similarly, sounders can be used to notify personnel of moving machinery, ensuring that everyone is aware of the machinery’s location and movements.
3. Specialized Industry Uses
- Gas detection: In industries where hazardous gases are present, beacons and sounders are vital for gas detection systems. When dangerous gas levels are detected, a safety light combined with an audible alarm will immediately signal workers to evacuate or take necessary safety precautions.
- Emergency services: For emergency services, including police, fire departments, and medical responders, sounders and beacons are used in various ways. On emergency vehicles, these devices, together with crucial safety signs, signal road users and pedestrians to reach their destinations quickly and safely.
- Rail transport systems: In rail transport systems, beacons and sounders play a role in signaling and safety management. They are used at level crossings, rail yards, and along tracks to warn of approaching trains or to indicate system statuses.
Choosing the Right Automation Signaling System
Here’s how to select the appropriate sounders and beacons for your automation signaling system:
Specific Industrial Environment
- Hazardous elements: Identify any hazardous elements in your environment, such as flammable gases or corrosive materials, to select sounders and beacons that are certified for safety in such conditions, ensuring they meet necessary safety standards.
- Noise levels: Assess the typical noise levels of your environment to choose sounders and beacons that give sufficiently loud signals or are equipped with adjustable volume settings, ensuring they can be heard clearly despite the background noise generated by machines.
- Area size: Determine the size of the installation area to select sounders and beacons with appropriate coverage. Larger areas may require high-intensity devices or multiple units to send signals, while smaller areas might need fewer strategically placed automated devices.
Weatherproofing
- Durability for outdoor use: For outdoor applications, select automated signals that are weatherproof, and designed to endure local weather conditions, such as rain, snow, and extreme temperatures. Look for devices with high IP ratings to ensure reliable performance and longevity in harsh environments.
Installation and Coverage of Sounders and Beacons
Installation Tips
- Plan your location: Plan the location of your automated safety systems to ensure they are placed in strategic spots where they will be most effective. Evaluate the layout of your workplace and identify areas where visibility and audibility are crucial. Remove all obstructions that could block the signal or diminish its effectiveness.
- Visibility and audibility: Ensure the signaling devices are positioned to be both visible and audible. Install beacons at eye level or higher where they can be easily seen, and place sounders where they can be heard clearly. Avoid mounting devices near barriers or machinery that might obstruct their signals.
- Mounting techniques: Use secure mounting techniques to ensure that sounders and beacons are firmly attached and oriented correctly. Follow the manufacturer’s guidelines for mounting to prevent vibrations or shifts that could affect performance.
- Electrical connections: Ensure all electrical connections are safely and correctly installed. Use appropriate wiring methods and electrical power cables to connect automated safety devices to the power supply to ensure they send correct signals to prevent hazards.
Coverage Considerations
- Area assessment: Conduct a thorough assessment of the area to determine the coverage needs of your sounders and beacons. Measure the dimensions of the space and evaluate the typical noise levels to choose devices with adequate decibel levels.
- Zoning: For large premises, set up your automated signaling devices to evenly distribute sound and visual signals across different areas. Implement a zoning system where sounders and beacons can be activated independently in different zones, allowing for targeted alerts and reducing the chances of signal overlap.
- Special areas: Pay special attention to areas that might be difficult to reach or where sound and light signals might be less effective. For example, enclosed spaces, areas with heavy machinery, or sections with high noise levels may require additional or specialized safety devices to send signals.
