Battery Smoke Alarms

Battery smoke alarms are quick and convenient to install, whilst also offering reassurance that your property and the people inside are protected from a fire.

For those looking for a cost-effective solution, the Battery optical smoke detector is ideal. The sensitive photoelectric system provides early warning of a potential fire and it has all the necessary safety features you'd expect – such as a handy test and hush button and a low battery indicator.

If you’re worried about the regular maintenance of a battery smoke detector, the Firehawk long-life smoke alarms have a 10-year lithium battery that runs for the whole life span of the device. Meaning no need for replacement or risk of tampering.

All alarms have a 100-day returns policy for added peace of mind – not that you’ll need it!

Long Life Smoke Alarms: 10 Years of Hassle-Free Protection

If replacing batteries is right up there with pulling teeth on your enjoyment list, opt for a smoke alarm with a ten year life lithium battery. Our sealed long life smoke alarm will not only work for ten years without the need for mains wiring or replacement batteries, but will also alert you when the unit is reaching the end of its useful life.

Sealed Smoke Alarms: Leave the Batteries Alone

Quite why people want to remove batteries from smoke alarms is beyond us, but any landlord or holiday letting owner will tell you, this does happen. Our Kidde 10-year sealed smoke alarm contains a long-life 10 year lithium battery that cannot be removed, so the unit will protect right up until it reaches the end of its useful life.

Sealed Optical Smoke Alarms: Small but Smart

The First Alert sealed optical smoke alarm is the smallest we've seen, but with a 10 year non-removable battery and a big hush button, it does the job really well. Use an optical smoke detector for areas with lots of combustible materials, such as bedrooms and living rooms, but not anywhere that might get steamy, dusty or smoky, such as near a kitchen or in a garage. In these locations, use a heat alarm instead - our First Alert model is one of the few battery operated heat alarms available.

Lighting Your Path To Safety

Smoke alarms will alert you to fire danger at any time of day or night, and our great value integrated smoke alarm and escape light offers you the additional benefit of being able to see your way to safety even if the power fails.

How to take the battery out of a smoke alarm

If you need to take the battery out of a battery-powered optical smoke alarm, you can do so easily yourself. Simply twist the outer casing anti-clockwise to release. Then gently use your fingers to remove the battery.

If you are changing the backup battery of a mains-powered smoke alarm, always remember to turn off the power supply beforehand.

How to change a smoke alarm battery

Once the cover has been removed, as detailed above, you can simply slot the new battery (usually 9V) into place. Return the outer casing by lining up the locating slots and twisting clockwise to secure.

Always remember to test the alarm when replacing the battery to ensure it's in full working order. To do this, simply press and hold the test/hush button until the device sounds. If your battery smoke alarm has an LED warning light, you should also check this is working.

How to remove a smoke alarm cover to change the battery

Most battery smoke alarm covers are easy to remove by rotating anti-clockwise. To secure the cover back into place, simply line up the locating slots and twist it back clockwise.

How to reset a smoke alarm after replacing the battery

Battery smoke alarms are simple to reset as they don't require disconnecting from power, unlike mains-powered detectors. In the rare event of a false alarm, you just need to silence the unit by pressing the hush/silencing button.

If the battery is running low and requires replacing, most alarms will sound an intermittent warning sound. You can quickly and easily replace the battery by following the steps above which should resolve and reset the device.

How often should battery smoke alarms be tested?

To ensure your battery smoke detector is in full working order, you should test the alarm weekly. Standard batteries should be replaced every six months, and long-life lithium batteries usually last the 10-year life span of the alarm.
