C-C550/M11 RSM Push To Talk Controller to Suit Motorola MTP3500

Keep critical radio comms clear, fast and hands-on in high-noise, high-wear environments. The C-C550/M11 remote speaker microphone (RSM) with body-worn push-to-talk (PTT) controller is purpose-built for industrial teams who need reliable communications when radios are carried under clothing, in harnesses or on belts. Designed for tough Australian worksites, it supports confident operation with heavy gloves and helps reduce downtime caused by damaged or unreliable accessories.

Built to withstand harsh job conditions, this unit is dust-tight and water submersible to 1 metre (IP67) and has been tested to MIL-STD-810G for environmental durability. The large, tactile PTT buttons deliver positive actuation even when wearing winter gloves or impact gloves, improving productivity by reducing missed transmissions and repeat calls. High-output speaker performance supports intelligible audio in noisy construction zones, processing plants and mobile equipment areas.

For safety-critical operations, remote activation of the radio’s emergency function is supported where the paired radio enables it (radio-specific). A rugged fibre-reinforced housing, clothing clip attachment and coiled cable help manage strain and reduce snag risk during movement, climbing and confined-space tasks.
