lines to confirm that:
• the expected number of End of Line
resistors is attached, and the A and B
circuits are evenly loaded;
• the impedance is as expected and
does not exceed the capability of the
associated amplifier configuration;
• all speaker lines are isolated from
earth.
Ensure adequately rated cables are used
for power supply and loudspeaker
connections, and route interlinking cables
away from power and loudspeaker
cables.

Amplifier Units, which are daisy-chained
to the DAU through the Audio-CAN bus;
see Figure 19 (page 17).
The ends of the Audio-CAN bus must be
terminated by 120 Ohm resistors.
If this DAX is the last unit connected to
the Audio-CAN bus, then an external
120 Ohm terminator must be fitted
between ‘CANH’ and ‘CANL’ terminals on
the DIN rail Interlink Adaptor.
Refer to Section “DIN Rail Interlink
Adaptor” (page 15) for terminal allocation
details.

DIN Rail Interlink Adaptor
The DIN rail Interlink Adaptor provides connections from the DAX amplifier system back to the DAU.
In order that the DAU can drive Expansion Amplifier Units, these units need to provide connections for the
low level audio from the DAU, the CAN bus, and the audio monitoring bus.
The low level audio, the CAN bus, and the audio monitoring bus connections are provided on a 16-way
ribbon cable connected to a box header underneath the amplifier motherboard of the DAX. By plugging this
16-way ribbon cable to the Interlink Adaptor, these connections are made available on screw-in terminals
suitable for the field cabling required to connect the DAX to the DAU.

1) These outputs are example for a DAU and a DAX with standard configuration, and driving eight loudspeaker
zones. These connections vary according to each system configuration.
As standard the DAU is configured to have outputs 1 to 4 connected to its built-in amplifiers configured for single
speaker circuit, and outputs 5 to 8 to be connected to Extension Amplifier Units.
As standard the DAX is configured as follows:
Audio 1 ÆSpeaker Output 1
Audio 2 ÆSpeaker Output 2
Audio 3 ÆSpeaker Output 3
Audio 4 ÆSpeaker Output 4
All outputs configured for single circuit speakers.
See Section “DAU Connections (for reference only)” (page 17).
2) The Audio-CAN bus comprises the CAN bus pair and the AUDIO MON pair.
The DAU can host one or more Expansion Amplifier Units, which are daisy-chained to the DAU through the Audio-
CAN bus. Therefore, only the first item on the Audio-CAN bus has the CAN and AUDIO MON pairs directly
connected to the DAU; see Figure 19 (page 17).
The ends of the Audio-CAN bus must be terminated by 120 Ohm resistors.
If the DAX is the last unit connected to the Audio-CAN bus, then an external 120 Ohm terminator must be fitted
between ‘CANH’ and ‘CANL’ terminals on the DIN rail adaptor.
3) Field cabling: cable ends to be fitted with suitable bootlace ferrules.
4) 16-Way ribbon cable to DAX connector: 16-Way IDC female connector.

3 DAX and DAU Positioning
In Voice Alarm and any safety application, the cabling should not leave the confines of the unit’s enclosure.
Therefore if fireproof interlinking cables are not used, then DAU and DAX units must be located immediately
adjacent to each other and interconnected by a bushed link.
By mounting the two enclosures side by side (Figure 21) or one above the other (Figure 22), the cabling can
be directly passed between the two enclosures without compromising the integrity of the interlinking cables.
L• A 25 mm bushed link between the two enclosures is advisable, as a 20 mm link will not
allow easy passage of the RJ45 connector.
• Due to the door hinge requirements in the side-by-side mounting the enclosures must be
spaced by more than 15 mm to allow the door to open fully on the right-hand unit, see
Figure 21.
