Motorola Accessory Kit - ANC RSM Ex 16 Ohm Standard Cable (PMMN4093A)

Motorola Accessory Kit – ANC RSM Ex 16 Ohm Standard Cable (PMMN4093A)

The Motorola PMMN4093A is an advanced Remote Speaker Microphone (RSM) featuring Active Noise Cancelling (ANC) technology and IMPRES audio. It is engineered to deliver clear and reliable communication in hazardous and high-noise environments.

Equipped with IMPRES technology, the microphone enhances voice intelligibility by suppressing background noise and amplifying quieter transmissions. Windporting technology minimizes wind noise and prevents water from blocking the microphone, ensuring clear audio even in challenging weather conditions.

Designed for durability, this RSM is rated IP67, meaning it is fully dust-tight and capable of withstanding immersion in water for at least 30 minutes. It is approved under ATEX and IECEx intrinsic safety standards, making it suitable for use in explosive gas and dust environments.

The Active Noise Cancelling feature enables effective communication in extreme industrial settings such as oil refineries or fire response scenarios. An integrated volume control on the RSM allows users to adjust audio levels without accessing the radio, improving efficiency and focus during critical tasks.

For emergency situations, the microphone includes a dedicated emergency alarm button. A programmable button provides quick access to frequently used radio functions.

The device features two audio connection ports. A 3.5 mm jack supports a discreet receive-only earpiece with a clear acoustic tube, while the Nexus connector offers an open ATEX/IECEx interface compatible with approved third-party headsets.
