Notification (Alarm) Reports

 

Notification (Alarm) Reports have two purposes:

 

  1. To report alarm information to personnel
  2. To prompt for acknowledgment of alarms

 

From the prospective of the RTU, notification is the process of reporting alarm conditions to eligible destinations. The specifics of what alarms are reported to which destinations depend on many settings within the RTU. These settings include destination types, how channels are linked to destinations, plus various session and annunciator parameters. 

 

The notification report for the destination includes information only for those channels that are in the destination's group. Thus, if there are unacknowledged alarms for channels that are not linked to a given destination (configured using Destination Channel Grouping), the person at the given destination will not hear about them unless they take special steps such as entering Program mode. 

 

In both incoming and outgoing sessions, the notification report is the first thing to occur after establishing connection.

 

The Notification Report consists of the following elements:

 

 

Alarm Report: Provides a channel status message for every channel with an unreported condition that is linked to the reporting destination. Front Panel sessions and Call-in sessions disregard channel/destination links and deliver reports for all channels.

 

Menu prompt: Front Panel and Over The Phone (OTP) VOICE mode sessions will give a warble tone and prompt the operator to enter one of the command keys (see table below) by offering the available menu choices. To interact with the RTU over the phone, you will use the telephone keypad buttons. These keystrokes act as commands to the RTU. If the RTU gets no response for 10 seconds, after repeating the menu choices three times, the session will be terminated. 

 

Listening Period: If so configured, OTP sessions will remain online with the RTU microphone enabled for 15 seconds to monitor sounds at the remote site. The RTU will then terminate the session.

 

Report delivery terminates when:
