System Concept

Working with chemicals or smoke, does require a respiration mask. The respiration mask is an audio obstacle and reduce the audio quality significantly.

​Mostly common scenario is that 2 users are working in pairs and at the same time being able to communicate in Full Duplex, and also being able to listen to the external radio. When the radio needs to be answered, a large easy-access PTT is needed.

Inside the mask the respiration is very loud, and will often interfear with the microphone. At IWCS we always recommend, to use noise cancelling boom microphones, as the most loud and clear voice comes from the mouth. Therefore any solution using iriComm headset ( for inside a HazMat suit ) or a FireComm ( Firehelmet plug-in ) solution, will provide the best sound quality.
