(1) Signals associated with life safety  
(2) Signals associated with property protection  
(3) Trouble signals associated with life and/or property protection  
(4) All other signals 
(NEW)

6.8.4.8 If the authority having jurisdiction determines that the
information being displayed or annunciated on a combination system is
excessive and is causing confusion and delayed response to a fire
emergency, the authority having jurisdiction shall be permitted to
require that the display or annunciation of information for the fire
alarm system be separate from, and have priority in accordance with
6.8.4.7, over information for the non-fire alarm systems.
