Description
Output n
Unique name for the audio output. The output can be
enabled and disabled using the check box.
Pilot tone
On, Off
Switches the pilot tone for loudspeaker monitoring on
(On) and off (Off). This pilot tone is used to monitor the
connected basic amplifier and the secondary side of its
transformer for short-circuits. It also supervises the
amplifier for failures and is used by the line supervision set.
GND supervision
On, Off
Switches ground supervision of the loudspeaker line on
(On) and off (Off).
Mains power
supervision
On, Off
Specifies whether the mains power of the connected
basic amplifier must be supervised. When Mains power
supervision is On and the mains power is failing, a fault
event is generated. Setting Mains Power Supervision to
Off when mains power is used, results in a system that
does not detect mains power failures.
Back-up power
supervision
On, Off
Specifies whether the back-up power of the connected
basic amplifier must be supervised. When Back-up power
supervision is On and the back-up power is failing, a fault
event is generated. Setting Back-up power supervision to
Off when back-up power is used, results in a system that
does not detect back-up power failures.
Lsp connection
Output A and B in same
area (redundant).
Output A and B in
separate areas (Not
redundant).
Class-A loop from
output A to B.
The outputs A and B each have loudspeakers that cover
the same area. Both outputs A and B are normally active. If
a line fault occurs on either output A or B, that output will
be switched off.
The outputs A and B each have loudspeakers that cover
different areas and are not close together. Both outputs A
and B are normally active. If a line fault occurs on either
output A or B, that output remains active. Only in case of
an overload or short circuit on either output A or B, that
output will be switched off.
The outputs A and B have connections to the same
loudspeakers. Output A is normally active, output B is
normally off. If a line fault occurs detected by a supervision
board, output B becomes active too.
Line/Lsp supervision
On, Off
Sets the line / loudspeaker supervision for group A or
group B.
Configure supervision
devices A
Opens a screen to configure LBB4441 and LBB4443
supervision devices (see section 43.3.5) on group A.
Configure supervision
devices B
Opens a screen to configure LBB4441 and LBB4443
supervision devices (see section 43.3.5) on group B.
