If the Praesideo system enters the voice alarm condition
the display of the network controller will automatically
show the ‘Emergency’ menu. This indication stays on as
long as the system is in the voice alarm condition (i.e.
until the voice alarm condition is reset).
If the Praesideo system enters the fault warning
condition the display of the network controller will
automatically show the ‘Faults’ menu with the current
number of active faults. This indication stays on until
either the rotary knob of the network controller is used to
navigate through the menu, or the system enters the
voice alarm condition. The ‘Faults’ menu will always be
present in the Network Controller menu. Individual faults
are present in this ‘Faults’ menu until they are reset or
until they are overwritten by newer faults The menu can
show up to 200 individual faults after which the oldest
faults are deleted when new faults occur.

legibility demands of this clause.
