alarm buzzer is reactivated when the faults have
been acknowledged but not yet resolved and reset.
• Report loudspeaker line fault (PRS-SVCO) -
Specifies whether LBB4440 Supervision Control
Boards that are used for line supervision (see also
section 43.3.5) must report faults immediately
(Immediate report) or must check again before
reporting faults (Recheck before fault reporting). When
the system must comply to evacuation standards,
select Immediate report to make sure that faults are
reported within 100 s. In systems with long
loudspeaker lines and many supervision boards, the
chance of getting a false (not valid) supervision fault
event can be reduced by rechecking before the fault
will be reported. Then the system is less sensitive to
disturbances in the communication caused by
external noise sources or crosstalk between wires.
• Disable network controller on internal fault
- This function is intended for systems that contain a
redundant network controller. If an internal fault in
the master network controller occurs (e.g., a flash
card error), the master network controller is disabled
and the spare network controller takes over the tasks
of the disabled network controller. If the system
contains only one network controller, select No.
