Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?

The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall.

During a fire, smoke initially rises and then spreads horizontally. Placing the smoke alarm in the centre of your ceiling means that it is closest to all four points of your room. This ensures that you receive the earliest possible warning of a fire.

For more information, read our guide to positioning your smoke alarm and guide to which smoke alarms are best for each room.

Q. Why is my smoke alarm beeping?

If your smoke alarm is sounding continuously, first check there is no smoke or fire in your property. If no fire or smoke is present, or the alarm is beeping intermittently, there are three main reasons why this may be happening:

  • It could indicate the alarm is over 10 years old and needs replacing. View our range of smoke alarms to find a replacement.
  • There could be a build up of dust inside. To clean it, you can use a vacuum cleaner or hair dryer on a cold setting.
  • It could also be an issue with the power supply or the batteries may need replacing.

Read our in-depth smoke alarm troubleshooting guide to find a full list of reasons and solutions.

Q. How long do smoke alarm batteries last?

  • 9V alkaline batteries last 12-18 months
  • Lithium batteries last around 5 years (some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm)
  • Sealed lithium batteries last the lifetime of the alarm (usually 7-10 years)
Please note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.

Q. What is the best way to dispose of an old smoke alarm or carbon monoxide detector?
