Introduction to alerts
Alerts is an Appspace feature that allows the broadcast of important or critical messages such as executive communications, weather updates, or emergency announcements across a network, immediately or at a scheduled time, via a sign. Alerts is supported on all Appspace App driven devices, and the Cisco Edge 340 media player.
Alerts consists of the following features:
- Broadcast Trigger API
You must first define your messaging categories and allocate color codes to them, i.e. Fire Alert, Emergency Evacuation Messaging, Service Expiry Notification, and such. You then create a messaging template and categorize it according to the messaging category you created. Finally, you broadcast the message across your network on a sign.
Account owner or Portal administrator permissions. Please refer to the table in the Introduction to user management article.
The following illustrates the layout of Alerts in Appspace.
The dashboard lists all the sites in a network that alert messages can be broadcasted to. You can also:
- Broadcast messages targeted to all sites, a group of sites, or a single site.
- Deactivate broadcasts currently in progress.
- Sync broadcast messages to registered sites within Appspace.
- View active and scheduled broadcasts.
- Generate a broadcast web handler via the Broadcast Trigger API. The Broadcast Trigger API is used to generate a web handler based on the user’s selection of the site and broadcast template. Once configured, external systems utilize the API method call, in the form of a URL, to instruct Alerts to broadcast the selected template to the chosen site(s).
The Templates page lists all the broadcast templates you have created. Here, you can create a template with a category (that you have predefined under the Category tab), and add content such as image files and web pages.
The Categories page lists all the broadcast categories you have created. You can add a name, description and allocate color codes to the category to indicate the urgency of the message. i.e. Emergency Alert, Severe Weather, Special Announcements, and such.
The following are content file types supported on Alerts.
- Image - JPEG, JPG, PNG, TIFF
- HTML Webpages - Url Snippet
- Dynamic Content - HTTP/HTTPS
