Alarms

When an Excel 10 has an alarm condition, it reports it to the central node on the E-Bus (typically, the Excel 10 Zone Manager).

See Table 9. Information contained in an alarm message is:

•Subnet Number:

E-Bus subnet that contains the Excel 10 node that has the alarm condition. Subnet 1 is on the Zone Manager side of the

router; Subnet 2 is on the other side.

•Node Number:

Excel 10 node that has the alarm condition (see Network Status).

•Alarm Type:

Specific alarm being issued. An Excel 10 can provide the alarm types listed in Table 9.
