smoke alarm detecting smoke

How to choose and maintain smoke alarms in your home

Picture this: it’s 2 a.m., the house is quiet and your family is sleeping. Then, a high-pitched beep comes from one of the rooms.

That sound? It could be the difference between a close call and a tragedy.

Home smoke alarms aren’t just helpful. They’re lifesavers. The problem is that too many homes still don’t have enough of them. Or, they have alarms, but they’re outdated, misplaced or completely silent because the batteries died months ago.

Let us fix that for you.

This isn’t about scaring you, but to keep the safety at your home as top priority. 

Keep in mind as well that there are strict regulations around smoke alarms, so we highly encourage you to read these, and if you are deciding for a proper smoke alarm hard wired system, please contact us as your trusted licensed electrician so we can do the job for you. 

Why fire alarms matter

We all know we should have smoke alarms. It’s a no brainer, right?

But most of us underestimate how fast a fire moves. A small spark can become a raging blaze in under three minutes. That’s barely enough time to grab the kids and get out.

A working fire alarm gives you a fighting chance. It doesn’t put out the flames, but it does buy you precious seconds. And when you’ve got little ones down the hall or elderly parents living with you, those seconds matter.

One stat that will help you look into smoke alarms quite quickly, is that you’re twice as likely to survive a house fire if you have working smoke alarms.

smoke alarm location

Where they should go

Let’s talk about where these should be installed. This part trips people up.

You might think one alarm in the hallway is enough. It’s not.

Here’s what fire safety experts recommend:

  • One alarm in every bedroom
  • One outside each sleeping area
  • One on every level of your home (including the basement)

And don’t forget the kitchen. Yes, you might get a false alarm while cooking, but it’s still important. Just place it a few metres away from the stove to avoid the constant beeping when you’re toasting your bread.

Avoid corners. And don’t put alarms near vents or fans, where airflow can mess with their sensors.

Also, keep in mind that the smoke rises. So always mount your alarms on the ceiling or high up on the wall.

Which type of fire alarm is the right one for your home?

Let’s break down the options. It’s not as overwhelming as it sounds.

There are two main types of smoke alarms: ionisation and photoelectric.

  • Ionisation alarms respond faster to fast, flaming fires. For example, kitchen grease fires.
  • Photoelectric alarms are better at detecting slow, smouldering fires. Like an electrical fault behind the wall.

Which should you get?

Honestly, both.

Some alarms are ‘dual-sensor’, which means they combine both technologies. That’s ideal. If you're unsure, go with photoelectric. They’re less likely to go off when you burn your toast but still highly effective.

Also worth noting that there are standalone alarms and interconnected systems. Interconnected ones talk to each other, meaning that if a fire starts in the basement, the alarm upstairs will still go off. You’ll hear it no matter where you are in the house.

If you’re building or renovating, hardwired, interconnected alarms are gold. But even if your home is older, there are wireless options available now. Easy to install. No electrician needed (though if you want help, we’re always here!).

smoke alarm batteries

Let’s talk batteries

Yes, wireless options have batteries, so don’t forget to change these every year.

Pick a date you’ll remember, add it on your calendar, and you’re done.

You can always choose alarms with 10-year lithium batteries. No yearly swap needed. Just test them regularly and you’re good to go for a decade.

That annoying chirping in the middle of the night? That’s your alarm begging you for a new battery, so don’t just take it down and forget about it. That chirp could save your life.

If you simply don’t want to worry about batteries at all, then think of hard wired options. For the safety of your home, give us a call as your trusted local electrician and we can go through some pretty good options. 

When to replace smoke alarms

Smoke alarms don’t last forever. Most people don’t know that.

They should be replaced every 10-years. After that, their sensors become less reliable even if the test button still works.

Not sure how old yours is?

Take it down and look at the back. You’ll find a manufacture date, which should give you a good idea on when it will be time to change or upgrade.

An Astill’s electrician can also do this for you. Instead of climbing up a ladder or a kitchen stool, we can assess and provide you with the best options.

How to Test Them

Testing your alarm takes literally 10 seconds.

Once a month, hit the test button. It should beep loudly. If it’s faint or silent, it’s not working.

Do this with your kids around. Let them hear the sound. Teach them what it means.

A fire alarm isn’t just a gadget, it’s part of your family’s safety plan.

What about carbon monoxide?

Different threat, same importance.

Carbon monoxide is silent. Odourless and deadly. And you won’t know it’s there unless you have a detector.

If you use gas appliances, wood burners or have an attached garage, you need a carbon monoxide alarm.

Some newer alarms are combination units: smoke and CO detectors in one. Handy, right?

Fire alarms and young kids

Here’s something not many people talk about.

Some children don’t wake up to the sound of a smoke alarm.

It’s scary, but true.

There are now alarms on the market with voice alerts, ones that actually call your child’s name. Research suggests they’re more effective at waking kids than beeping alone.

If you have little ones, it’s worth considering. And as always, practice your family escape plan regularly. Make sure everyone knows where to go, how to get out, and where to meet.

Very important, we suggest you educate yourself and family in relation to fires and alarms, so that safety can also be in the back of the minds of children.

Smoke alarms common mistakes

Common mistakes 

Let’s call out a few fire alarm fails we’ve seen more than once:

  • Removing the alarm because it keeps going off while cooking. 
  • Not having one in the basement or attic.
  • Forgetting about alarms in guest rooms or granny flats.
  • Relying on an alarm that’s over a decade old.
  • Putting alarms too close to windows, fans or vents.
  • Not testing them. Please don’t wait until there’s smoke in the air.
  • Finally, one of the biggest mistakes is not calling an electrician. Why not? At Astill’s, your safety is a priority, and it is within our scope to assess alarms, suggest you the best options and install hard wired ones throughout your home.
