Failover operation
To address the possibility of a communication failure or device trouble, you can create a failover operation in the
VM-CU for the VM-DACT. Failover operates by enabling and disabling various accounts defined for the project.
On detection of a fault or trouble, project correlations disable accounts on the failed VM-DACT and enable
matching accounts on the backup VM-DACT.
Failover operation results in a system that is resistant to trouble arising from telephone lines, VM-DACTs, or the
VM-CPU module. The operation can be limited to a single panel or can span two or more panels anywhere in a
network.
In systems with a single VM-DACT, you can include a second VM-DACT that acts as a redundant unit. In systems
with two or more VM-DACTs, you can program the system so that the units back up each other, while still
handling their normal traffic.
Monitoring and diagnostics
See “LED indicator diagnostics” on page 131 for the LED states.
Connecting a MIR-PRT/S serial printer
The MIR-PRT/S serial printer can be connected to a VM-1 panel to provide a printout of system events such as
status changes, active events, and reports. The printer is an 80-character line width, freestanding printer that uses
standard form feed paper.
Figure 29: MIR-PRT/S serial printer
An illustrated setup guide is included with the printer that contains detailed instructions for assembling the printer,
installing the print drivers, and performing other basic tasks. Refer to the guide when unpacking, assembling, and
setting up the printer. A user guide is provided on the CD included with the printer. Refer to the user guide for
instructions on using the front panel to configure printer settings.
Notes
• For supervised printers, use MIR-PRT/S printer model D22300A (120 V).
• If connecting the MIR-PRT/S printer to a serial port that is shared with a CDR-3 Bell Coder, refer to
“Connecting a CDR-3 for coded tone output” on page 99.
