The Vocia VA-8600 Fail Over Module (VFOM-1) is an optional module that can be fitted to the Vocia VA-8600 series amplifiers. The VFOM-1 allows for automatic amplifier channel Failover switching in either a 7:1 mode or a 3:1 mode. The VA-8600 Failover Module occupies the option module slot (Slot 10) of the VA-8600. The use of the VFOM-1 prevents use of the PARM-1 in the same amplifier chassis.
• 7:1 Failover mode: Amplifier channel 8 is assigned as the Failover channel for channels 1 through 7. The amplifier can be configured from 2:1 Failover up to 7:1 Failover if fewer channels are required. However the Failover channel will always be channel 8.
• 3:1 Failover mode: Amplifier channels 4 and 8 are assigned as Failover channels for channels 1 through 3 and 5 through 7 respectively. The amplifier can be configured for 2:1 Failover if fewer channels are required. However the Failover channels will always be 4 and 8.
The VFOM-1 is enabled in the Vocia software under the VA-8600 Options dialog window. As the PARM and Failover Module both use the Option Slot (Slot 10) of the amplifier, if the PARM has been selected, it will not be possible to configure 3:1 or 7:1 Failover. Similarly if the Failover Module is selected, PARM functionality will not be able to be configured. The VA-8600 will signal a faulty or incorrectly assigned option module via the Alarms and Logs reporting.
Please see the VFOM-1 Manual for installation instructions.
