A repeating alarm pattern may signal smoke or carbon monoxide
A loud repeating alarm, voice warning, visible smoke, burning odor, or carbon-monoxide alert is not a low-battery chirp. Get outside and follow emergency instructions.
Why this result fits
- The sound is a repeating group of loud beeps or a voice warning rather than one isolated chirp.
- There is smoke, fire, burning odor, a CO message, or anyone feels ill.
- The alarm pattern is uncertain and cannot be safely dismissed.
What to do now
Leave the apartment
Get everyone outside using the planned exit. Close doors behind you if you can do so without delay.
Call 911 from outside
Report the alarm type, smoke or odor, symptoms, and building location.
Stay outside
Do not re-enter until the fire department or other qualified authority says it is safe.
Alert management after emergency services
Use the building emergency channel once everyone is safe.
Stop and escalate if
- There is any smoke, fire, gas odor, burning odor, or CO warning.
- Anyone has headache, dizziness, nausea, confusion, or breathing trouble.
- The alarm pattern cannot be identified safely.
What not to do
- Do not remove a battery, silence the alarm, or search for the source before leaving.
- Do not use an elevator during a fire.
- Do not re-enter for belongings or pets.
