Test Smoke & Carbon Monoxide Detectors

Ensure all ceiling smoke and CO alarms produce loud alert signals and replace aging batteries.

Supplies You'll Need

• Step stool or ladder
• Fresh 9V or AA batteries (if chirping)
• Microfiber duster

Step-by-Step Instructions

1. Walk to each detector unit (bedrooms, hallways, basement, living room).
2. Press and hold the 'TEST' button for 3-5 seconds until the horn sounds a loud pattern.
3. Vacuum or wipe away dust and spiderwebs from the sensing vents using a duster.
4. If any alarm chirps intermittently or fails the test button, replace its batteries immediately.
5. Replace any alarm past its rated life — smoke alarms at 10 years and CO alarms typically every 5-10 years (manufacture date is printed on the back). Sensors wear out even when the test button still sounds.
6. Log test confirmation in your choreloop maintenance journal.
