It is a known fact that you are more likely to die in a fire if you do not have a smoke alarm working in your home. Something so simple can prevent a fire from spreading and can also save your life.
Our smoke detectors can be powered by the mains or by batteries. If you do have a battery-operated smoke alarm, then you must ensure that the batteries are working at all times. If you do forget to check them, then the alarm will alert you when the batteries are running low. All smoke alarms will have a test button on them. You can check the alarm is working by pressing this.
