Screen FlowAlert Broadcasts
One-click override of every scheduled screen for safety announcements, evacuations, severe-weather alerts, and time-sensitive messages.
Content types
Three ways to compose an alert, depending on how much time you have:
Text message
Type a message — it renders as a full-screen banner with configurable font, color, and background
Media file
Upload or select an existing image or video from the media library
Existing page
Broadcast any published page — useful for pre-prepared emergency templates
Alerts activate within seconds of creation — player polls every 30 seconds and the alert fires on the next heartbeat cycle.
Targeting scope
Alert Broadcasts can target the entire client network, specific device groups, or individual devices. Select "All devices" for site-wide emergencies or narrow the scope for location-specific announcements.
Alert Broadcasts always run at priority 10 — the highest in the system. They override all scheduled playlists and other broadcasts immediately.
Banner font controls
Banner alerts honor configurable font family and font color — so severity is visible at a glance. Choose from system fonts or match your brand identity. Background color is independently configurable.
Activation & deactivation
- play_circleActivate immediately — Alert goes live on next player heartbeat (≤30s)
- stop_circleDeactivate — Single click to end the alert; screens revert to scheduled content
- scheduleAuto-expire — Set an end time so the alert stops automatically
Priority resolution
When multiple alerts are active simultaneously, Screen Flow resolves by specificity: device-level targets take precedence over group targets, which take precedence over client-wide broadcasts. Within the same specificity level, the most recently activated alert wins.
