The Story Behind the Nimbus


Modern fabric technology has created extremely effective turnout gear for firefighters. This protects them so well from the harsh, intense environments that they encounter a situation that is somewhat counterproductive! Firefighters are so well protected from the heat that they can become less than adequately aware of their developing surroundings. In some reported cases, they have found themselves in life-threatening circumstances.

The Nimbus AT-100 is an extremely lightweight device that’s designed to fit any helmet; the firefighter does not even need to remember to switch it on!

This smart device is always on. In normal temperatures it is in “ready mode”. This is  shown by a gentle flashing green LED that gives you and your colleagues the peace of mind that your Nimbus is  on and ready to protect you!

As the firefighter moves around his/her environment, the Nimbus is constantly monitoring and making calculations based on his or her exposure to heat and heat changes.

As the temperature of the environment changes, it alerts the firefighter by a simple sequence of colour changes and vibrations to the helmet. The vibration signal passes directly through the helmet to the firefighter’s head, while the LED colour changes are visible in the firefighter’s peripheral vision, thus giving both visual and sensory indications.

At the same time, a high intensity LED will also illuminate from the rear of the unit, giving your colleagues a visual indication by way of a buddy light system.

As the environment becomes more and more intense, the AT-100 will continue to give simple and easily-recognised sensory and visual warnings until critical levels are reached. At which point, the AT-100 will deliver unique, more intense warning signals,  intended to remind the user that a decision point is imminent based on the environmental information being received.

So, no buttons to press, no screens or gauges to remember to look at, it’s always there working to assist you and alert you to your situational awareness needs.
