EPIC 3 Radio Direct Interface (RDI) Voice Amplifier


The 3M Scott EPIC 3 Radio Direct Interface (RDI) voice amplifier enhances SCBA facepiece voice intelligibility and delivers clear two-way radio communications when operated with compatible handheld field radios and remote speaker microphones (RSM).

Compatible with all 3M Scott AV, Vision, and Promask series facepieces and breathing apparatus systems, the EPIC 3 RDI provides 3M Scott customers with the safety and operational benefits of enhanced tactical voice communications while extending the value of their SCBA and Personal Protection Equipment.

The EPIC 3 RDI operates directly with compatible Bluetooth®- enabled handheld field radios and matching remote speaker microphones, allowing customers to utilize their existing radio equipment to simplify system operation, deployment logistics, and reduce technology spend.

Integrated noise suppression technology removes environmental ambient noise from the facepiece and radio voice communications, allowing first responders to be clearly heard and understood when communicating with incident victims, team members, incident commanders, and remote dispatchers.

Durable purpose-built design and construction ensure the EPIC 3 RDI will perform long term in high-temperature use case environments, enhancing worker safety while minimizing customer maintenance costs.
