FireFly Siren: Smarter Audible Alerts for Safer Underground Operations
Underground environments demand fast, clear and reliable communication. Visual signals are essential, but in low‑visibility or high‑noise conditions, crews need an additional layer of protection. The new FireFly Siren by IoT Automation delivers exactly that.
Built to integrate seamlessly with the FireFly lighting system, it provides powerful, distributed audible alerts that strengthen emergency response and improve operational safety throughout your operation.
Built for Underground Mining & Tunnelling
The FireFly Siren is engineered for durability and simplicity. Its compact, robust design allows it to withstand harsh production areas while remaining easy to deploy anywhere along existing FireFly lighting strings. Using the standard FireFly connector, installation is plug-and-play, minimising disruption and enabling rapid scaling across headings, declines or fixed plant locations.
Power efficiency is a core part of the design. Operating on 12–60VDC at just 4W, the module ensures reliable performance without placing additional strain on site power infrastructure. An integrated Li-Po battery backup provides up between 4-6 hours of runtime, ensuring alerts remain active even during power interruptions.
Connectivity that Enables Smarter Safety
The FireFly Siren is more than just your traditional siren. With Wi-Fi (802.11b/g/n) and Bluetooth Low Energy connectivity, it becomes part of the broader IoT Automation network, enabling remote configuration, automation and seamless integration with other safety and emergency response systems.
Through the IoT Hive web platform, teams can customise, schedule and automate tones across the entire site. Whether it’s a pre-blast countdown, an all-clear signal or an emergency evacuation tone, the FireFly Siren keeps communication consistent and coordinated.
Customisable Tones for Real-World Scenarios
Underground operations rely on clear communication during critical events as well as day-to-day operations. The FireFly Siren can support up to five programmable and fully customisable tones for scenarios, for example:
- Pre-blast and blasting notifications
- All-clear signalling
- Emergency or evacuation warnings
- Localised equipment or infrastructure alerts
This flexibility ensures that every alert is unmistakable and tailored to the way each operation runs.
A Connected, Site-Wide Warning System
When integrated with environmental monitoring systems such as gas, dust or air quality sensors, the FireFly Siren becomes part of a powerful automated safety network. Alerts can be triggered instantly based on sensor thresholds, providing immediate notification across working areas.
The ability to mount the FireFly Siren on mobile machinery or fixed plant infrastructure as a stand-alone device also allows companies to create mobile safety zones, extending coverage into areas where FireFly lighting strings may not be installed.
Why It Matters
In high-risk environments, early warning and clear communication save lives. The FireFly Siren ensures every worker receives the same timely information, improving response times and reducing confusion during critical events. With its combination of robust hardware, smart connectivity and seamless integration with FireFly lighting, it delivers consistent, site-wide coverage that enhances the reliability of emergency and operational alerts.
By unifying visual and audible signals, mining operations gain a safer, more responsive and more intelligent communication system, one designed specifically for the realities of underground work.
