Emerson Specifying Alarm Reporting Types, Setting up an E2 to be an Alarm Annunciator

10.16.1Specifying Alarm Reporting

Types

Apart from storing alarms it generates in its own Alarm Advisory Log, E2 can also report alarms it gener- ates or receives in order to notify personnel. E2 can report alarms in several different ways.

10.16.1.1 The Display Line

Alarms that occur within an E2 (or which are received by an Alarm Annunciator from another E2) may be reported to the header display at the top of the screen. When an alarm is reported to the display, the word “*ALARM*” flashes underneath the time at the top of the screen, allowing site managers or supervisors to see that one or more alarms are active for the E2.

10.16.1.2 The Alarm Output

Each E2 has a single digital output that reacts to alarm reports. An alarm can be reported to this output, in which case the output turns ON and remains on until the alarm condition has returned to normal.

10.16.1.3 Dial-Out

Alarms may be sent to remote alarm receivers via the modem defined for the controller. Possible dial-out devices include a PC running UltraSite, a printer, a fax machine, and a digital pager. Dial-out sites are configured in Section 10.16.3.

10.16.1.4The Echelon Network (The Alarm Annunciator)

If multiple E2s exist on a network, you may choose to send alarms from all E2s across the Echelon Network so that they may be picked up by the Alarm Annunciator.

The Alarm Annunciator is the primary alarm reporting device in a multiple-device E2 Network. The Alarm Annunciator gathers all alarms posted by all devices on the Echelon Network, records them in its own advisory log, and applies its own set of alarm filters to determine if the alarms should be dialed out, reported to its display, or sent to its Advisory Output.

There are several benefits to having an Alarm Annun- ciator:

•An Alarm Annunciator makes it possible to handle all alarm dial-outs for all controllers with a single modem or network card.

•Users can view alarm notifications and alarm logs for all controllers from the Alarm Annunciator.

•Only the Alarm Annunciator needs to be pro- grammed with alarm filter settings for dial-out, out- put, and display. All other controllers may be programmed to simply send all alarms to the Alarm Master via the LonWorks Network.

10.16.2Setting up an E2 to be an Alarm Annunciator

Any E2 on the network that has a modem or Ethernet connection can be set up as an alarm annunciator, but only one alarm annunciator per network is allowed. To set up from the Main Menu:

1.Press (System Configuration)

2.Press  (System Information)

3.Press (General Controller Info)

4.Set Alarm Annunc field to Yes.

NOTE: When the E2 is set up as an Alarm An- nunciator, the Home screen becomes the Alarm Log.
