Smoke alarms are your first line of defence in protecting your home and loved ones from the dangers of fire. It’s important not to neglect their care and upkeep so they can work properly when you need them most.

Don’t worry – smoke alarm maintenance is easier than you might think, including for wireless and photoelectric smoke alarms. By following a few straightforward steps, you can ensure they are always in top condition.

Why Regular Maintenance Matters

Maintaining and cleaning your smoke alarms is more than a routine task – it’s a life-saving measure. Here’s why regular upkeep of your fire alarms is essential:

  1. Improved Reliability: Clean and well-maintained alarms respond more accurately to smoke, reducing the risk of a malfunction during critical times.
  2. Minimised False Alarms: Dust, insects, or debris can trigger unnecessary alarms, which can be frustrating and lead to complacency.
  3. Prolonged Lifespan: Well-maintained smoke alarms last longer, saving you money on replacements.

General Smoke Alarm Maintenance Schedule

Having a regular smoke alarm maintenance schedule is essential to keep your home safe and secure. Follow this simple schedule to ensure your alarms are always in working order.

Every Month

  • Check the indicator light to ensure it blinks, indicating the alarm is powered.
  • Gently vacuum or brush the exterior to remove dust and cobwebs that may block the sensors.
  • Press the test button to test your smoke alarm. Once you hear a loud beep, you’ll know it’s working correctly.

Every 3 Months

  • Wipe the surface of the alarm with a cloth. Tap the alarm and vacuum gently around the circumference to clear the inside of any debris.
  • Inspect for cracks or other signs of wear that may affect performance.
  • Optionally, you can also spray insect repellent on a cloth and gently wipe the area around the smoke alarm (ceiling, walls, etc) to deter insects, or remove the alarm and spray the surface around the base. However, never spray the repellent directly at the alarm as that may trigger it.

Every Year

  • Replace alarm batteries with replaceable batteries, especially for alarms using 9V batteries or 9V battery backups. Make sure to use a reputable battery brand.
  • Check the manufacturer’s guidelines for alarms with sealed batteries, but continue testing them monthly.
  • You can also set an annual reminder in your phone calendar to make sure you replace your batteries on time.

Every 10 Years

  • Since smoke alarms are an essential life-saving device, it’s recommended — and in some cases, required by law — for smoke alarms to be replaced every 10 years. Refer to the date of manufacture printed on the alarm.
  • Upgrade to a newer smoke alarm model with advanced and improved features.

Steps to Deep Clean Your Smoke Alarm

1. Gather Your Supplies

You’ll need:

  • A vacuum cleaner with a soft brush attachment.
  • A dry or slightly damp microfibre cloth (avoid using water directly on the alarm).
  • A ladder or sturdy step stool to reach the alarm safely.
  • Your smoke alarm’s user manual for specific cleaning guidelines.

2. Remove the Batteries

Before cleaning, make sure to slide the alarm off its base and remove the battery within.

3. Wipe the Exterior

Use a dry or slightly damp cloth to wipe the alarm casing. You can also vacuum around the circumference gap and tap the alarm around the edge or use an air compressor to clean it.

4. Inspect for Damage or Infestation

While cleaning, check for signs of wear, corrosion, or physical damage. Replace the alarm if you notice any severe damage (cracks, burn marks, etc).

Also be sure to check for any spiderwebs inside or around the alarms, as well as whether any have crawled inside, as their presence can impede the alarm’s effectiveness.

5. Reassemble and Reconnect

After cleaning:

  • Reinstall the battery and turn the alarm back on.
  • Test the alarm to ensure it is operational.

Frequently Asked Questions

Can I clean my smoke alarm with water?

Never use water directly on a smoke alarm, which could damage the electronics. Always use a dry or slightly damp cloth instead.

How can I stop dust from building up inside my smoke alarm?

It is important to plan the location of your alarm carefully during installation to avoid dusty areas. After installation, regular cleaning with a vacuum cleaner every three to six months can help minimise dust accumulation.

How do I prevent insects from entering my smoke alarm?

Wipe the ceiling or wall around the alarm with a cloth sprayed lightly with insect repellent. Never spray the repellent directly on the alarm, as this can damage it or trigger false alarms.

What should I do if my smoke alarm keeps going off after cleaning?

If your smoke alarm goes off after cleaning, check for remaining dust, debris, or insects inside the unit. Ensure the alarm is installed in an appropriate location away from cooking fumes or steam. If the problem persists, consider replacing the whole unit.
