External power amplifier

The voice alarm controller has 1 external power amplifier output (line level, 1 V) and 1 external
power amplifier input (100 V) to connect an external power amplifier. The function of the
external power amplifier (e.g. a Plena Power Amplifier 360/240W) depends on the channel
mode for which the voice alarm controller is configured (see section 1-Channel mode
operation, page 77 and section 2-Channel mode operation, page 78).
