Signal lamp for visual alerting
In emergencies, the speed of response is crucial. The more clearly an alarm signal is perceived, the more effective the reaction will be. Signal lamps (also known as warning beacons) play a vital role, especially in situations where the sound of a siren or a smartphone notification alone is not enough.
In this blog, we discuss the importance of signal lamps in alarm systems and how they contribute to a safer working environment.
What is a signal lamp?
A signal lamp is a visual warning device that emits a bright, repetitive light signal to draw attention to an alarm. They are often used in combination with other alerting methods such as sirens or app notifications.
Why use signal lamps?
1. Inclusive alerting for the hearing impaired
Not everyone can perceive sound signals. A signal lamp provides a visual solution, ensuring that people with hearing impairments are immediately informed of an emergency. This makes alerting more inclusive and accessible for everyone.
2. Effective in noisy environments
In industrial areas or locations with high background noise, alarm sirens can easily be drowned out. Signal lamps attract the attention of employees even in loud surroundings.
3. Dual impact through visual and audible signals
Combining sound and light strengthens the alert and ensures it is less likely to be missed. This is especially important in situations that require immediate action, such as during an evacuation.
4. Tailored warnings
Signal lamps can be strategically positioned in areas where extra visibility is required — for example, in enclosed spaces, poorly lit corridors, or hazardous zones in factories.
5. Easy to install
No professional installer is required; it’s a true plug-and-play solution. The signal lamp only needs a power connection and also includes a built-in backup battery. This redundancy ensures it remains active even during a power outage.
Applications of signal lamps
Signal lamps are used in a wide range of scenarios:
- Fire safety: As part of a fire alarm system to support evacuations.
- Industry: To warn employees of dangerous situations, such as gas leaks or technical malfunctions.
- Security: For visual alerts in case of intrusions or emergencies.
- Healthcare: To quickly alert staff to medical emergencies or evacuations within care facilities. (Note: in this context, the device functions solely as an optical alarm indicator.)
How signal lamps enhance MultiBel alerting?
At MultiBel, we understand the importance of versatile alerting solutions. Signal lamps can be seamlessly integrated into our safety platform. This means the signal lamp is triggered simultaneously with other alerting methods, such as the MultiBel app.
By combining the signal lamp with app notifications, voice messages, and optional sirens, we create an alerting system that works for everyone — regardless of the situation.
Conclusion
Signal lamps are a powerful addition to any alarm system. They visually reinforce alarm signals, making alerting more accessible and effective. Whether in a factory hall, an office, or a healthcare facility, signal lamps help create a safer environment for everyone.
