leads which are colour coded and should be connected as
shown in the diagram below.
The conduit running from the supply to the sounder must
include an equipment grounding conductor that is at earth
potential to facilitate ground connection of the device. A number
of loudspeakers can be connected in a chain to the same
supply using field installed wiring compartments that are
appropriate for the hazardous location, provided that the
conductor at earth potential can be readily connected to the
ground lead on each loudspeaker in the chain.
