output levels.


The amplifier operates on 115/230 VAC mains with option

for automatic switching to 24 VDC battery backup in case
of power failure. The amplifier is supervised by a pilot tone
to continuously check the signal path, and a fault will be
reported by an indicator in front combined with a closing
contact for external fault warning.
 
The amplifier has a built in selectable chime generator
activated by a priority switch to give an alert signal in front
of a message.
