L3Harris Unveils XL EXTREME 400P Emergency Responder Radio

Rugged, Reliable and Resistant to Severe Environments

L3Harris Technologies has unveiled the XL EXTREME 400P, the first handheld radio designed to meet the most rigorous two-way, portable RF device standards for emergency responder communications.

The XL EXTREME radio and all-new speaker microphone combine to create a rugged solution designed for optimal performance under severe environmental conditions, such as those experienced by firefighters, military personnel and hazmat units.

The XL EXTREME is designed to meet, and in many cases exceed, the latest industry-accepted fire protection standards as we continue our mission to address the most demanding needs of our customers,” commented Nino DiCosmo, President, Public Safety and Professional Communications. “We leveraged the breadth of L3Harris’ expertise in developing this product, combining the most advanced RF technologies used in military tactical radios, with product materials that allow space vehicles to survive the heat of atmospheric reentry. The result is an extremely survivable, high-performing radio that the industry has never seen.”

The XL EXTREME 400P has demonstrated ruggedness and uncompromised voice quality, after flame exposure testing at over 950°C. It features heat-resistant thermal materials, a reinforced watertight seal, and unique thermal-rated displays. It delivers clear audio transmission and reception with industry-leading noise cancellation, operates over multiple broadband networks and includes integrated Wi-Fi, Bluetooth and GPS. Easy to use, the XL EXTREME series offers heavy-duty ergonomics like glove-friendly knobs and a large emergency button, as well as customer-demanded features like visual group indicator providing quick confirmation that all users are on the same group or channel.

From start to finish, L3Harris went all in on the development of the XL EXTREME radio, to make sure that our customers have exactly what they need for their missions […] We incorporated best-in-class features and functionality to make this device easy to use, and we backed it up with unprecedented testing to prove its durability and crystal-clear communications in the harshest environments,” DiCosmo added.
