2.3. OPERATION STATUS INDICATION
The actual operation status of the Hi-Delta 302ACE-
2342ACE appliances is indicated through led panels on site.
The Hi-Delta is an integrated system that controls its safe
operation thoroughly. Forwarding the 24V AC collected
error signal that applies on the ALARM output of the inner
panel whenever the “SAFETY” light is on is an expedient
compromise for building management systems.
Each signal that is indicated on the outer panel can be
forwarded to a building management system but it increases
the costs significantly, while not giving any significant
advantage in most cases. Knowing the meaning of the inner
panel lights is unnecessary for the user. Detailed
information about them can be found at 4.2.10.
