Emergency Siren
The SOS App allows you to activate a loud emergency siren on your device to:
- Draw public attention quickly.
- Deter potential threats or attackers.
- Signal distress in crowded, isolated, or dangerous environments.
You can trigger the siren manually from the app dashboard or configure it to activate automatically during emergency events like fall detection.
Overview
Using the Emergency Siren, you can:
- Emit a loud alarm noise to alert nearby people.
- Use sound as an additional safety signal during emergencies.
- Distract or deter threats, enhancing your self-defense readiness.
- Signal your location to responders if you are trapped or immobile.
Ensure your device’s media volume is turned up to maximize siren effectiveness.
Why the Emergency Siren is Useful
| Situation | Benefit |
|---|---|
| Threatened by strangers | Loud alarm draws attention, deterring attackers. |
| Medical emergency in public | Alerts bystanders to assist quickly. |
| Stuck in isolated areas | Siren sound helps searchers locate you faster. |
| Fall Detection Trigger | Automatically calls attention if you cannot respond manually. |
In many situations, sound is faster and more visible than messages or calls.
How to Trigger the Emergency Siren
You can manually activate the siren through the SOS App:
- Open the SOS App.
- Tap the Emergency Siren button from the dashboard.
- The siren will start playing at full device volume immediately.
You can stop the siren anytime by tapping the Stop Siren button inside the app.
How to Configure Auto-Siren Activation
You can also configure the siren to activate automatically:
- Open the SOS App.
- Navigate to Settings → Emergency Actions.
- Enable Auto-Siren During Fall Detection.
- Save your settings.
Now, if a fall is detected or an automatic SOS event occurs, the siren will sound without manual interaction.
Best Practices for Using the Emergency Siren
| Recommendation | Why It Helps |
|---|---|
| Test the siren in safe environments | Ensure it functions and is loud enough for your device. |
| Keep your media volume high | Siren depends on your device's audio output levels. |
| Use discretion when manually triggering | In crowded areas, avoid false alarms unless truly needed. |
| Combine siren with other actions | For maximum safety, also send SOS Alerts alongside the siren activation. |
Common Questions
Will the siren sound if my phone is locked?
Yes.
If configured, the siren can be triggered from Quick Access Tiles or automatic Fall Detection even when the screen is locked.
Can I customize the siren sound?
Currently, the SOS App uses a built-in loud siren sound optimized for emergencies.
Customization options may be introduced in future updates.
Does the siren work without an internet connection?
Yes.
The siren relies only on local device hardware and does not need internet access.
Will the siren continue if the app is minimized?
Yes.
Once triggered, the siren continues playing until you manually stop it, even if the app moves to the background.
Troubleshooting
| Issue | Solution |
|---|---|
| Siren too soft | Increase your device’s media volume manually before emergencies. |
| Siren button unresponsive | Restart the app and ensure background permissions are granted. |
| No siren sound after triggering | Verify device media output settings and disable Silent Mode if active. |
| Siren stops suddenly | Some battery savers may restrict continuous audio; whitelist the SOS App if needed. |
The Emergency Siren gives you a powerful sound-based defense tool — alerting others to help you faster and deterring potential threats before they escalate.
By combining audible alerts with your location-sharing and recording features, the SOS App builds a complete personal safety system that works even offline.
Sound the alarm. Stay protected.
