Lit to indicate that a system fault has been detected in the PA/VA system. This requires immediate action as part(s) of the system used for emergency functions may have been affected. A system fault will always cause the ‘fault’ LED to be lit as well.
A system fault is triggered by a failure of any processor or memory, critical to the Voice Alarm system, including those of the VAR8(EN54) itself. A communication fault between the VAR8(EN54) and any equipment or device that has been configured at the VAR8(EN54) and that is critical to Voice Alarm functions will also trigger a system fault. fault

Twisted pairs, individually screened. Recommended type: BELDEN 8451 LSHF
The rack and field cabling should be as described in the diagram shown in Figure 3 (page 17).
4. Audio and data network cabling (on VAR8(EN54) with Network Interface Card):
Twisted pairs with overall foil screen. Recommended type: FS cables 2407 POFYH
The Upstream side of the network connection is isolated RS485. The rack and field cabling should be as
described in the diagram shown in Figure 2 (page 17).
Overall screened. Recommended type: BELDEN LS0H
The rack and field cabling should be as described in the diagram shown in Figure 3 (page 17).
6. Audio outputs on RJ45:
Cabling: overall foil screened. Recommended type: CAT5 STP or FTP LS0H

Recommended Installation Procedure
!
!
1) Please read and observe the “Safety and Precautions” section on page 19 of this manual.
2) For cable termination connectors and pinout details, refer to Section “2 Connections” (page 10).
3) For EMC compliance, wiring should be according to the diagrams shown in Figure 2 (page 16) and
1. If installing a VAR8(EN54) with a Network Interface Card, note that the Network Interface Card is configured, by default, for network operation using 3 audio network channels. If stand-alone operation or 1 or 2 channel only network operation is required, set the links on the Router board as
described in “Link Settings for Stand-Alone, 1 or 2-Channel Network Operation” on page 9.
2. Mount the VAR8(EN54) into a 19-inch equipment rack.

3. Connect the rack and field cabling for control ports, audio inputs, audio outputs, signal monitoring,
CAN bus, RS232, RS485 as appropriate; see Figure 1. Refer to Section “2 Connections” (page 10) for
pinout and signal details.
If the ANIC8 Network Interface Card is fitted, then connect the network cabling.
The upper control port, A/B outputs, and network interface connectors may not be present, depending on the VAR8(EN54) variant being installed.

Link Settings for Stand-Alone, 1 or 2-Channel Network Operation
!
!
1) This procedure is required when the VAR8(EN54) is fitted with a VAR-ANIC Network Interface Card, and stand-alone operation, or 1 or 2 network channel only operation is required instead of the default
3-channel network operation.
2) If any difficult is found in accessing the links, please refer to ASL.
1. Remove the unit’s lid by undoing the screws located on the top of the unit.
The link position is shown below.
