How Often Should You Change Your Home's Smoke Detector?

It's that time of year again - when you dust off the cobwebs in your home and tend to those pesky tasks you've been putting off all winter. One of those tasks may be replacing your smoke alarm, especially if it's been more than a year since it was last replaced. Today we'll walk you through the process of replacing your smoke alarm, whether it uses batteries or hardwired power. We'll also share some tips on how to choose the right smoke alarm for your home.

Your smoke detector is critical because it's your first line of defence against a fire in your home. That's why it's important to change the batteries every year and replace the entire unit every ten years. If you have a hardwired smoke alarm, you should also test it monthly by pressing the test button. Although you might worry about annoying the neighbours, it's a simple step that could save lives.

Why should you replace the batteries every year? Smoke alarms have a limited lifespan, and the batteries are one of the first things to go. The simple test button will tell you if you need to change them before, but once per year is normally enough.

Why change the unit every ten years? The sensors in smoke alarms can become less sensitive over time, which means they might not go off when there's a fire. If you've had the same unit for more than ten years, it's probably time for an upgrade.

If you're not sure how to change the batteries or replace the entire unit, don't worry - we have some advice for you. Firstly, make sure you have the right tools. You'll need a screwdriver to remove the old unit, and a drill to put the new one in place.

Once you've got everything you need, follow these steps:
  • Use the screwdriver to remove the old unit from its mount on the ceiling. If it's difficult to remove, don't force it too much.
  • Carefully disconnect the wires from the back of the old unit.
  • Take your new unit and connect the wires to its terminals. Make sure they're tight so they don't come loose.
  • Use the drill to put the new unit in place. Start with a small hole and then make it bigger until it's firmly in place.
  • Put the batteries in and test the unit to make sure it's working.
That's it; you've successfully replaced your smoke alarm. Be careful when you're doing this so that you don't damage the ceiling or wires. If you haven't changed your smoke alarm before or are nervous about the idea, contact a Qualified Electrician for assistance.

Emergency Power, Battery Power, Ceiling Location

As well as changing the smoke detector unit, professionals can also teach you about emergency power, battery power, and the location of the alarm on the ceiling. Where should you place your alarm on the ceiling? The answer is not as straightforward as you might think. In fact, most people don't even know that there's more than one right answer when it comes to ceiling placement.

There are three main types of smoke alarms: ionization, photoelectric, and dual sensor. Depending on which type you have, the advised location can differ. Furthermore, the advice regarding battery and emergency power changes.

It's important to have a working smoke alarm in your home. By changing it regularly, you can be sure that it will work when you need it most. Hopefully, this guide has been helpful and given you the confidence to change your smoke alarm yourself. If not, don't hesitate to contact a professional for assistance!
