Shining the Light on Safety: How to Choose Between LED and Xenon Fire Alarm Beacons

 From the placement of emergency exits to the reliability of fire suppression systems, every detail matters when it comes to safeguarding lives and property. In this dynamic landscape, where technology continually evolves to meet the demands of modern safety standards, your choice of beacons is a crucial consideration. 

When it comes to these gadgets, two options stand out: the LED and Xenon alarm beacon. While LED technology has seen a surge in popularity in recent years, Xenon remains a contender with its unique advantages. LED lights are known for their durability and low maintenance requirements, making them ideal for long-term use in various applications. On the other hand, Xenon lights are known for their rapid response time and ability to penetrate through smoke and other obstructions, ensuring that they grab attention when it matters most. Choosing between these two technologies depends on the specific requirements of the application. 

Light Output

When it comes to the light output of fire alarm beacons, there's a notable difference between these two technologies. LED lights offer a steady, continuous glow that remains visible for an extended period. As soon as you activate them, they reach their maximum brightness instantly, providing consistent illumination over time. On the other hand, Xenon lights produce a short but intense flash of light that covers a wide area. Instead of maintaining a constant brightness, Xenon beacons emit a powerful burst of light, making them highly effective at grabbing attention in emergencies. While the flash duration may be brief, it's enough to alert individuals to potential hazards and prompt them to act. 

Lifespan

When it comes to the lifespan of these devices, there's a notable difference between an LED and a Xenon alarm beacon. LED lights are known for their longevity, offering approximately 50,000 hours of continuous operation. This means that they can maintain their effectiveness for an extended period without needing frequent replacements. On the other hand, Xenon lights have a shorter lifespan, typically providing around 10,000 hours of operation. While Xenon beacons still offer a considerable amount of usage time, they may require more frequent maintenance and replacement. 

Upkeep

When it comes to maintenance, there's a notable difference between LED and Xenon fire alarm beacons. Xenon bulbs tend to fail suddenly and completely at the end of their lifespan, requiring immediate replacement once they reach their limit. On the other hand, LEDs undergo a gradual deterioration over time. Instead of abruptly failing, they may become less bright or efficient as they age. This gradual degradation provides a warning sign, giving users time to plan for maintenance or replacement before the light ceases functioning altogether. So, while Xenon bulbs demand more immediate attention when they fail, LEDs offer a more predictable maintenance schedule, which allows for proactive management to ensure the continued reliability of fire alarm systems. 

Adaptability

An LED beacon differs from a Xenon one in its adaptability when it comes to flash patterns. With LEDs, you have the flexibility to control or program flash patterns according to their specific needs. This means they can customise the flashing sequence to suit different situations or preferences. On the other hand, Xenon beacons typically provide single flash sequences without the ability to adjust or customise the pattern. So, if you require versatility and the ability to tailor flash patterns to different scenarios, LEDs offer a more adaptable solution compared to Xenon models. 

Application

LEDs are well-suited for situations that demand notification through various flash patterns. They offer versatility, making them ideal for scenarios where different types of alerts or signals are necessary. Additionally, they work well in environments where there are limitations on circuit capacity, as they’re more energy-efficient compared to Xenon models. The latter is more suitable for applications in larger spaces where a simple single flash notification suffices. Their intense, bright flashes are effective in grabbing attention across expansive areas, which makes them valuable for situations that require widespread alerting. 

Visibility

Xenon fire alarm beacons emit a full spectrum of white light, spreading in every direction, ensuring maximum visibility in all surroundings. This omnidirectional emission makes them highly effective in environments where you need visibility from various angles. On the other hand, LED light is more directional, meaning it emits light in a specific direction. While this can be advantageous in some scenarios where you need focused illumination, it may not provide the same level of visibility from all angles as Xenon beacons. 

Colour

So, what colour are the alert beacons? The colour of alarm beacons plays a crucial role in conveying messages and guiding responses, so here's a breakdown of what different colours typically signify: 

• Red light: This colour is universally recognised as a warning of danger or hazard. It signals that viewers should stop or move to safety immediately;  
• Amber light: Amber or yellow indicates a need for caution and awareness. It serves as a warning that a potentially hazardous condition could arise soon, prompting viewers to be vigilant of their surroundings; 
• Blue light: While commonly associated with emergency services, blue beacons should not be used on roads. They typically indicate that viewers need to clear the area; 
• Green light: Green signifies safety or security. It indicates that an emergency is being addressed or that operations are running smoothly without issues. Green may also serve as a status indicator, such as signalling the proper functioning of machinery or environmental conditions; 
• White beacon: White emits the brightest light and is used to project indications over longer distances. Its wavelength allows it to travel further and appear brighter. In poor visibility conditions, white lights can highlight different areas or equipment, particularly useful for large moving objects; 
• Magenta lights: Magenta warns of immediate danger or hazard, often serving as an alternative to red in specific contexts. It signals the need for action, such as evacuating an area or addressing broken equipment. Commonly used in industries like oil and gas, magenta indicates extremely high levels of combustible gas or serves as a safety system for roadside machinery.
