Remote Speaker Microphone Zone 1/21 – IS-RSM3B.1

The Bluetooth® Remote Speaker Microphone is the ideal addition to PoC and lone worker protection applications for Zone 1/21. The lightweight device has an ergonomic design and is easy to operate even when wearing gloves. The RSM has a powerful loudspeaker (up to 103 dB) and the microphones are positioned so that they can pick up voice input evenly from all directions. Two built-in noise-cancelling microphones reduce background noise, ensuring clear voice transmission. In conjunction with the DSP controller (Digital Signal Processor), unwanted noise is minimised in real time, enabling clear communication in particularly noisy working environments.The RSM is specifically designed for devices in the IS54x.x and IS94x.x series.
