3.8 Call station
The call station can be connected to one of the shielded
RJ45 call station sockets on the voice alarm controller
with a Cat-5 Ethernet cable. See figure 3.4 for
connection details.
If the cable between the call station and the voice alarm
controller is longer than 100 m, the call station must be
connected to a 24 V(DC) power source. See figure 3.5
for connection details.
3.9 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).
