Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
8.6.2 The audible indication shall be silenced
automatically if the VACIE is automatically reset from the
fault warning condition.
Since the Praesideo system does not offer automatic
reset from the fault warning condition this requirement
does not need to be implemented.
8.6.3 If previously silenced, the audible indication shall
resound for each newly recognized fault.
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.
8.7 Reset of fault indications Praesideo is compliant.
8.7.1 Indications of faults as required in 8.2 shall be
capable of being reset
a
automatically when faults are no longer recognized,
and/or
The Praesideo system does not offer automatic reset of
faults
b by a manual operation at access level 2. 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.
8.7.2 Following reset as specified in 8.7.1, the indication
of the correct functional conditions corresponding to any
received signals shall either remain or be re-established
within 20 s.
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.
8.8 Transmission of the fault warning condition Praesideo is compliant.
The VACIE shall have provision for transmitting, by
means of at least general fault signal, all faults specified
in 8. This fault signal shall also be given if the VACIE is
de-energized.
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.
