What is it?

The Setcom LiberatorMAX™ CSB-901MAX KIT is a wireless, full-duplex intercom-only headset system designed for fire apparatus and emergency response teams. Built for rugged environments, this system enables hands-free communication across crews without the need for push-to-talk radios. It offers unmatched clarity, range, and ease of use, making it ideal for high-noise, high-stress situations.

How is it used?

The CSB-901MAX headsets are used for team intercom communication within fire trucks, ambulances, and rescue vehicles. They operate without a base station for intercom-only use or can be paired with the MS-900MAX Master Station for expanded radio integration. Users simply turn on the headset, match the channel, and begin communicating instantly—no syncing or pairing required.
