Description of BS 6353:1983 1983

This British Standard specifies requirements for underground loudspeaker communication systems that are equipped with the facility for connecting speech and other audio signals to another loudspeaker communication system and/or to an appropriate surface switchboard to form a loudspeaker communication network.
