How to test smoke and carbon monoxide alarms

Teach: How to test smoke and carbon monoxide alarms

What to say

Press and hold each smoke and carbon monoxide alarm's test button once a month, change batteries yearly or at the first chirp, and replace alarms by the date on the back. Every bedroom, the hall outside sleeping areas and every level need smoke alarms. If a carbon monoxide alarm sounds, get everyone outside first, then call 911.

What to show, in order

1. Walk the home and count the alarms: every bedroom, outside each sleeping area and on every level, basement included.
2. Hold down the test button on every alarm until it beeps loudly, reaching high ceilings with a broom handle instead of a chair.
3. Replace batteries yearly, or right away if an alarm chirps; sealed ten-year alarms need no battery changes.
4. Read the manufacture date printed on the back, and swap out any alarm older than its maker's stated replacement age.
5. Make sure there is a carbon monoxide alarm on every level and near sleeping areas if the home has any fuel-burning appliance or an attached garage.
6. Agree with everyone at home on two ways out of each room and a meeting spot outside.
7. Put a monthly reminder in your phone for test day.

When to stop and call a professional

• A carbon monoxide alarm sounds: get everyone and any pets outside into fresh air, then call 911 or the fire department from outside.
• Hardwired alarms need replacing or keep sounding for no reason: use a licensed electrician.
• Anyone has headache, dizziness or nausea that eases outside: seek medical help and have fuel-burning appliances checked.

The check question

Ask: How often should you press the test button? Answer: Once a month
