nector and Belden 1855A cable, or an equivalent.

Making Alarm Connections
The router provides system alarms that notify you of a malfunction, such as when a fan or power
supply is not functioning properly. Alarms can be connected to an external alarm indicator that dis-
play visual signals when an alarm is activated. The NV6257 power supply, the NV8000 power sup-
ply, and the router each have alarm connections. Miranda does not provide external indicator
equipment, however this manual provides instruction on wiring the alarm connection. See
External
Alarm Indicators on page 48.
Both the NV6257, NV8000, and the router send status information to the router control system. For
more information on the alarm connections, see
System Alarm on page 14.
How to Make Alarm Connections
1 On the rear of the NV6257 (Figure 3-1) or the NV8000 (Figure 3-5), locate the ‘Alarms’ con-
nection.
2 Connect to the ‘Alarms’ connection using a DB25 connector and cable.
3 Connect the other end of the cable to an external alarm indicator. See External Alarm Indicators
on page 48 for information on wiring the DB25 connector.
