Critical alerts override every screen.
Turn your digital signage network into a life-safety communication system. When emergencies happen, alerts take over screens instantly with clear, actionable information for everyone in your facility.
Your screens become your emergency voice
The Emergency Alert System integration transforms your signage network from a content delivery tool into a critical safety infrastructure. When an alert is triggered, all targeted screens immediately override their scheduled content with high-visibility emergency messaging. Alerts support visual and audio components, multilingual text, and automated escalation rules.
What you can do with override every screen.
Three capabilities that make this integration essential for your digital signage network.
Screens respond in seconds
When an emergency alert is triggered, Hangar.Media pushes the alert to every targeted screen within three seconds. Scheduled content is suspended and the alert takes full control of the display with high-contrast visuals and optional audio.
From trigger to every screen showing the alert, it takes less than three seconds across 200 displays.
Sub-three-second push to all targeted displays
Full-screen takeover with high-contrast emergency template
Optional audio alert through connected speakers
Pre-built for every scenario
Hangar.Media includes pre-built alert templates for common emergencies including fire evacuation, severe weather, active threat lockdown, medical emergency, and shelter-in-place. Each template uses proven color coding, iconography, and messaging frameworks developed with safety professionals.
We activated a lockdown drill and every screen showed clear instructions within seconds.
Fire, weather, lockdown, medical, and evacuation templates included
Customizable text, colors, and instructions per template
ADA-compliant contrast ratios and font sizing
Alert the right areas
Not every emergency affects the entire building. Target alerts to specific floors, wings, buildings, or screen groups. A fire alarm on the third floor can override third-floor screens while other floors show a general awareness message.
Zone targeting lets us alert specific building areas without causing facility-wide panic.
Screen group and zone-based alert targeting
Different alert severity levels per zone
Cascade rules to escalate from local to building-wide if needed
Four steps to connected screens.
From setup to live content in minutes, not days.

Built for every sector.
See how different industries use this integration to drive results.
Campus-wide lockdown alerts
Universities and schools use the emergency alert integration to push lockdown instructions to every hallway, classroom, and common area screen simultaneously during security incidents.
HealthcareHospital code alerts
Hospitals display code blue, code red, and other emergency codes on floor-specific screens with clear instructions for staff and calming messages for patients and visitors.
CorporateOffice building evacuation notices
Corporate campuses use digital signage to display evacuation routes, assembly points, and all-clear notices during fire alarms and emergency drills.
PublicGovernment facility threat alerts
Government buildings and public facilities use screen-based alerts to communicate threat levels, shelter-in-place instructions, and severe weather warnings to occupants.
Common questions. Straight answers.
How fast do emergency alerts appear on screens
Emergency alerts override screen content within three seconds of activation. Hangar.Media uses a priority push channel that bypasses normal content scheduling to deliver alerts with minimal latency.
Can alerts be triggered automatically from fire alarm systems
Yes. Hangar.Media can integrate with fire alarm panels, building management systems, and security platforms via API, relay contacts, or webhook triggers to automatically activate screen alerts when alarms fire.
What happens to scheduled content during an alert
Scheduled content is paused for the duration of the alert. Once the alert is cleared, screens automatically resume their normal programming from where it was interrupted.
Can I test the system without causing a real alert
Yes. Hangar.Media includes a test mode that displays alerts with a visible test banner so occupants know it is a drill. Test alerts are logged separately and do not affect production alert statistics.
