Quick Summary
A Ring Alarm siren that won't stop is almost always caused by a sensor that triggered the alarm and hasn't been cleared, a delay in the app's disarm command reaching the base station, or a stuck contact sensor reporting an open door or window. The fastest fix is to disarm via the Ring app or keypad, then identify which sensor triggered the alarm and address it. If the app is unresponsive, use the physical keypad — it works even without internet.
Why the Alarm Won't Stop
Step 1: Disarm via Ring App Open the Ring app → tap the alarm tile → tap Disarm. Enter your PIN when prompted. The siren should stop within 5 seconds. If the app is slow: wait 10 seconds — the command may still be processing. If the app shows 'Offline' or the command doesn't work: proceed to Step 2.
Step 2: Disarm via Physical Keypad
The Ring keypad works locally and does not require internet. Walk to the Ring keypad (usually near the front door). Enter your 4–8 digit PIN. Press the Disarm button (checkmark or shield icon). The siren should stop immediately. If the keypad is unresponsive: check that it's powered (plugged in or has charged batteries).
Step 3: Identify and Clear the Triggering Sensor
After disarming, find out which sensor caused the alarm to prevent re-triggering. Ring app → Event History → look for the most recent alarm event. The event will show which sensor triggered (e.g., 'Front Door Contact Sensor opened'). Check that sensor physically: ensure the door or window is fully closed. If the sensor shows 'Open' in the app but the door is closed: the sensor may be misaligned or faulty. Realign the sensor magnet: the magnet (smaller piece) should be within 1 cm of the sensor body when the door is closed.
Step 4: Replace Low Batteries in Sensors
Low battery sensors can misfire and trigger false alarms. Ring app → Devices → select the triggering sensor → check Battery Level. If battery is below 20%: replace the battery (most Ring sensors use CR123A or CR2032 batteries). After replacing, re-test the sensor: open and close the door/window and verify the app shows the correct Open/Closed status.
Step 5: Reconnect the Base Station
If the base station is offline, the app can't send disarm commands. Check the base station LED: solid blue = online; flashing blue = connecting; red = offline. If offline: check the Ethernet cable (if wired) or Wi-Fi connection. Unplug the base station for 30 seconds, then plug back in. Wait 2 minutes for it to reconnect. Test disarming via the app.
Step 6: Contact Ring Support for Persistent Issues
If the siren continues after disarming and the above steps don't resolve it: Ring app → Help → Contact Us → select 'Ring Alarm.' Ring support can remotely inspect the base station and sensor logs. If a sensor is confirmed faulty, Ring will replace it under warranty (1-year standard, 2-year extended).
