table 43.18: Spare outputs configuration

Item	Value	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	On, Off	Specifies whether the mains power of the connected
supervision		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	On, Off	Specifies whether the back-up power of the connected
supervision		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.
Interconnection	On, Off	Sets the interconnection supervision between spare basic
supervision		amplifier channel and the main basic amplifier channels.
Configure supervision		Opens a screen to configure LBB4441 and LBB4443
devices		supervision devices (see section 43.3.5) on group B.
Amplifier channel		With the < and > buttons main amplifier channels can be
selection		assigned to a spare amplifier channel.
