The Fire Safety Speaker Microphone (FSSM) solves the problem of a lack of adequate communi- cation capability for those wearing face masks, breathing apparatus, or protective body suits. Any of the above items essentially block the wearer's speaking and hearing audio paths. Consequently, verbal communication between the wearer and others in the vicinity is rendered impossible. Additionally, the FSSM provides for typical 2-way communication through the user's portable radio.
