FAQs (3)
Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?
A.

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. How often should I replace my smoke alarm?
A.

You should replace your smoke alarm every 10 years. This is because the sensors in the alarm become less sensitive and may not activate when a fire is present.

Sign up to our smoke alarm reminder service to be reminded by text or email when your alarm is due to be replaced.

Q. How do I fit my smoke alarm to the ceiling?
A.

Smoke alarms can be either screwed to the ceiling using the holes on the base plate (screws provided), or fixed in place using either a self-adhesive sticky pad or a self-adhesive magnetic mounting kit.
