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 (see figure 3.6). The function of the external
power amplifier (e.g. a PLN-1P120 Plena Power
Amplifier) depends on the channel mode for which the
voice alarm controller is configured (see section 4.5.11).
