Installation and Setup 2-7

The DB-9 connector also allows alarms to be sent to the NMS (Input alarms).

These alarms are called General Alarms and are numbered 1 through 4.

• Pin 1 (shorted to pin 8) sends NMS General Alarm 1

• Pin 2 (shorted to pin 8) sends NMS General Alarm 2

• Pin 7 (shorted to pin 8) sends NMS General Alarm 3

• Pin 8 (shorted to pin 8) sends NMS General Alarm 4.

The alarms that trigger the relay are listed in Chapter 3, Table 3-1. The relay will be

activated only if the specific Alarm trap is enabled (not masked).
