Why is my smoke alarm beeping?

What to do

1. 1

   Check for a real fire first

   If the alarm is sounding continuously, check for smoke or fire and get everyone out if there is any doubt. Call 000.

2. 2

   Find the chirping alarm

   In homes with several alarms, stand under each one. Interconnected alarms may all sound, but usually only one has the low-battery warning light.

3. 3

   Replace the battery if it is replaceable

   For battery-only alarms, use a stable step ladder and replace with the battery type shown on the alarm. Some hardwired alarms have a replaceable backup battery; follow the manufacturer's instructions.

4. 4

   Check the date on the alarm

   Smoke alarms should be replaced ten years from manufacture, or sooner if the manufacturer says so. Many sealed alarms have a ten-year battery and the whole unit must be replaced.

5. 5

   Test the alarm

   Press the test button after changing the battery. If it does not sound, or keeps chirping, it needs replacing.
