Compliance
Since the Praesideo system does not offer automatic reset
from the fault warning condition this requirement does not
need to be implemented.
After the audible indication has been silenced (by
acknowledging all faults) the Praesideo system will resound
the indication upon occurrence of a new fault or
reoccurrence of a previously resolved fault.
Praesideo is compliant.
The Praesideo system does not offer automatic reset of
faults
Faults can be manually reset by acknowledging and
resetting them individually or all in one action.
Acknowledging and/or resetting faults individually can be
done via the front panel menu of the Network Controller
and via the Open Interface. Acknowledging and/or
resetting all faults in one action can be done via the front
panel menu of the network controller, control input
contacts, call station keys or the Open Interface.
If any individual fault is reset while it is not actually resolved
in the system, the Praesideo system will report the fault
again within 20 seconds. If all faults are reset in one action,
all individual faults that are not actually resolved in the
system are reported again within 20 seconds.
Praesideo is compliant.
Output contact 5 of the Praesideo network controller is the
fixed Fault alarm indicator output. This relay output contact
indicates no fault when open (energized) and indicates a
fault when closed (de-energized). If the Praesideo system is
de-energized this output contact is closed, therefore the
fault signal will also be given.
