Exhibition Label Text: Used in an emergency to extablish communications between the mine telephone system and
a rescue and first aid base. It could be used for speaking or signalling using a set code of rings.
One ring meant ‘help wanted’, two rings meant ‘repeat message’ and so on.
This system meant that messages could be passed on by rescuers wearing breathing apparatus.
