The mic provides superior audio, temperature and environmental performance, and operates in immediate Danger to Life and Health (IDHL) situations.

The L3Harris Fire Speaker Microphone is one of the first public safety mics to perform in the intense temperature environments described by NIST 1477. Engineered with special high-temperature materials (including a coiled cord) and features to perform in extreme heat, this mic provides superior communications and enhanced safety for firefighters.
