The WIN-911 Announcer provides text-to-speech (TTS) announcement of alarm events through the local sound device. Such output is typically routed to a PC speaker, enabling operators on-site to hear details of the alarms that WIN-911 is monitoring. Output can also be routed to a plant announcement system or radio transponder. Multiple instances of the WIN-911 Announcer can be installed across the network to provide local audio output potentially against distinct subscriptions.
The WIN-911 Announcer is available for version 4.19.24 or later of WIN-911 Standard, Interactive, and Advanced. A free 30 day trial of the software is available for download.
Microsoft .NET 4.8 or later is required. The installer for .NET 4.8 is included with the download of WIN-911 as well as the USB drive if you ordered a physical copy.
An enabled sound device is required to install the Announcer. On some PCs, a sound device is not enabled until speakers are plugged into the audio port.
Windows Desktop Experience must be enabled on Server 2016 and Server 2019
You can download the installer directly from here.
The installer is also located in the Tools folder of the WIN-911 download and USB drive.
The name of this WIN-911 Announcer instance will be defaulted to match the local computer name, but you are free to use any name as long as it is unique on your network.
Specify WIN-911 Dispatcher Computer
When first launching the WIN-911 Announcer you will be prompted for the location of the WIN-911 Dispatcher host. If this tool has been installed on the WIN-911 Dispatcher computer, then you are ready to test.
If the WIN-911 Dispatcher is located on another computer, specify its computer name here before testing. Once tested, click the Save button to enable access to the remainder of the configuration.
Start WIN-911 Announcer with Windows
The option to start the WIN-911 Announcer with Windows is defaulted for the current windows session.
IMPORTANT: If multiple users log in to this computer, be sure to launch the Announcer from your start menu once for each such user to enable this automatic startup for their future Windows sessions.
Enable Connection Warning
By default, the WIN-911 Announcer will announce connectivity loss with the Dispatcher. You may disable or modify the details of this announcement here.
All alarms assigned to a Strategy in WIN-911 will be announced by any subscribing instances of the WIN-911 Announcer. The Add and Delete buttons can be used to configure the Strategies of interest for this instance of the WIN-911 Announcer.
If desired, you may specify a prefix to announce before all alarm messages for a specific Strategy. For example, if you would like the announcer to say, “Safety Alarm” prior to announcing every alarm from the Safety Strategy, type that prefix here. You may also adjust the replay interval for alarm messages from a specific Strategy. By default, the WIN-911 Announcer will replay messages every 15 minutes; this can be configured between 5 and 59 minutes or set to 0 if no repeat is desired.
For all Subscriptions, you may enable/disable the announcement of any of the four alarm states. If you are not interested in hearing alarms after they are acknowledged, simply disable the appropriate states.
By default, WIN-911 Announcer will remain silent if its target Dispatcher is in Standby Mode. This behavior is typically desired but can be modified here.
Upon review of these settings, click Save and continue to the next tab.
This section of the configuration allows you to specify which local audio device and TTS Voice should be used to announce alarms. If the local computer has more than one sound device, you may need to ensure that the correct device is selected. Use the preview button to play the editable text to the left of the button. If you are not hearing the audio preview, confirm speaker connectivity and the audio device selection. The preview can also be used to compare TTS Voices and options.
To accept this configuration, click the Save button and continue to the next tab.
description provided by default. You can preview your format against a stand-in alarm event, but we recommend listening to test alarm from your SCADA system to fine-tune the format.
TIP: see the online Alarm Event property mapping document for your SCADA.
If you wish to display seconds or dates in your alarm properties related to time, use the provided control under the Insert button.
If you are targeting a remote WIN-911 Dispatcher, you will need to verify that your DNS can resolve the WIN-911 Dispatcher hostname or set up an accessible static IP address. You must also configure your firewall is permitting communications from the WIN-911 Announcer to the WIN-911 Dispatcher (TCP ports 80 and 4020).
Finally, you will need to ensure that the user account under which the WIN-911 Announcer is executing can be authenticated by the WIN-911 host.
If both machines are members of the same domain and the executing user is a domain user, then this condition is satisfied.
If the machines are on separate domains, you will need to establish a domain trust relationship.
If the machines are not on a domain at all, you will need to configure a user with the same name and password on the WIN-911 host in order to secure communications.
If you are experiencing issues with announcements, check the Windows Event Viewer logs under “WIN-911” for errors or warning reported by the WIN-911 Announcer. This information will aid the diagnostic effort.
