The New Nimbus™ AT-100 is the latest in performance protection technology designed to enhance the firefighter’s situational awareness at a fire scene. The Nimbus accurately monitors ambient temperatures surrounding the firefighter, alerting him or her of changes in temperature. It can even alert the wearer of an imminent flashover.

The Nimbus is a helmet-mounted heat sensor: it attaches to a firefighter’s helmet via a standard torch mount; it operates automatically, providing simple yet effective protection to firefighters while working at a fire scene.



Using simple-to-manage software, users can set up multiple temperature threshold points in the Nimbus. When each temperature threshold is reached, the Nimbus alerts the firefighter via green, amber, and red LED lights and at high temperatures, a  vibration to the side of the head. It also alerts fellow firefighters via additional high-brightness, smoke-penetrating LEDs. Device programming is usually completed at the station but can be set up to order (dependent on quantities ordered).
