Here’s the simple maintenance routine I follow to make sure our alarms are ready when we need them most.
1. Test Monthly (It Only Takes a Minute)
Every month—usually on the first Saturday when I remember—I grab a broom handle and press the “Test” button on each alarm. That unmistakable beep reassures me it’s still working.
Testing once a month ensures:
The sensor is active
The battery has enough charge
The connection (for interconnected alarms) is still working
Pro tip: If you have multiple alarms linked together, pressing the test button on one should trigger all of them. If they don’t, it’s time to investigate.
2. Vacuum Around the Vents
It surprised me how much dust and cobwebs can build up around smoke alarms, especially in hallways or near kitchens. Dust can block sensors and cause nuisance alarms—or worse, stop the alarm from detecting smoke quickly.
Every six months, I use the soft brush attachment on the vacuum to gently clean the vents. It only takes a few seconds per alarm but can add years to their performance.
3. Change Batteries Annually (Unless Sealed)
If your alarms have removable batteries, you should replace them once a year—even if they still seem fine. Low batteries often cause that dreaded 3am chirping sound.
Some newer models, like the ones we installed, have sealed 10-year lithium batteries, which saves this step. But even with long-life alarms, it’s still worth doing regular tests.
4. Check Expiry Dates
All smoke alarms have a limited lifespan, usually around 10 years. On the back or inside the cover, you’ll find a manufacture date or expiry sticker.
I set a reminder on my phone for each alarm’s replacement year. It’s one of those tiny tasks that could literally save lives.
5. Be Mindful After Renovations or Dusty Work
After any home reno projects—especially sanding, painting, or plastering—dust can infiltrate the sensors. It’s a good idea to:
Clean the alarms thoroughly
Re-test after the work is complete
Replace filters if your alarm model has them
When we installed a new kitchen, our smoke alarms picked up more airborne dust than we realised, leading to a few false alarms until we cleaned them.
6. Listen for the Chirp
That random chirp you hear in the middle of the night? Don’t ignore it. It’s usually a low battery warning or an end-of-life alert. If changing the battery doesn’t fix it, the unit probably needs replacing.
Quick Maintenance Checklist
✅ Test alarms monthly
✅ Vacuum alarms every 6 months
✅ Change batteries yearly (unless sealed)
✅ Check expiry dates annually
✅ Clean after major dust exposure
✅ Replace units after 10 years
Final Word
Keeping your smoke alarms maintained isn’t complicated—but it’s one of the most important safety routines you can have. A few minutes a month could be the difference between early warning and tragedy. And once it becomes a habit, you barely think about it—you just sleep better at night.
