3.3. Audio outputs module
1)
Channel "A" FAIL Contact. NO (Normally Open) output contact. Its activation is associated with
the surveillance functions of the "A" channel. Use the software P.A. Manager to configure in
which cases the contact is activated (by detecting errors loudspeaker line high or low
impedance, short circuit, open line or error amplifier...).
FAIL contact is an open collector output as shown in the diagram of figure 8.
2)
CHANNEL "A" LINE IN. Channel "A" amplifier speakers line connection.
3)
CHANNEL "A" LINE OUT. Channel "A" speakers line connection.
4)
CHANNEL "A" RJ45 Connector. +4dB audio output, balanced through transformer. The output
level is adjustable through Call Point software.
RJ45 PIN OUT
Pin 1: AUDIO H (HOT) output signal.
Pin 2: AUDIO C (COLD) output signal.
Pin 3: +24 VDC input to monitoring the amplifier.
Pin 4: Not used.
Pin 5: Not used.
Pin 6: PRIORITY output contact. Open collector output.
Pin 7: Not used.
Pin 8:
Metal Shield:
5)
OUTPUT "A" FAIL LED indicator. Indicates FAIL output contact activated.
6)
OUTPUT "A" PRIORITY LED indicator. Indicates activation of the channel "A" priority output contact (pin 6 of the OUTPUT "A"
RJ45 connector).
7)
CHANNEL "B" indicators and connectors. It has the same functionalities as the elements of channel "A", applied in this case to
channel "B".
8)
POWER LED indicator. Indicates that the audio outputs module is supplied.
