Best Smoke Alarm to Buy in the UK for 2022

Protect your space

As is reported, rescue and fire services attended more than 150,000 fires last year only in England, and while the number of fire fatalities dropped to its lowest ever figure, 240 people died. To prevent such events, and save lives and your property consider buying a smoke alarm for your security system. This device can give you an early warning of a fire before it’s going bad and will give you the time of getting everyone safely out of the house and calling for help.

For instance, most properties require more than one smoke alarm, alongside detectors for measuring heat and carbon monoxide (CO) levels in the state. These devices protect their users against the notorious silent killer, or cover areas like the kitchen, where fires can originate but a smoke alarm would be impractical. And while it’s not hard to find a decent smoke alarm at a nice, affordable price, there are some older therefore less effective models on the market, and there are a few options or features that you better look out for. We’re here to point those out for you based on our personal experience of testing them and steer you towards the best smoke alarm for you.

How to choose the best smoke alarm for the security system

There are two basic types of smoke alarms, which differ in the way they detect smoke. In the first case, small amounts of radioactive isotopes (too small to cause any harm) cause ionization in the air inside the smoke detector. If smoke enters, these ionized air molecules react and cause a change in electrical behavior, setting off an alarm. These ionization detectors are sensitive and responsive, but are also prone to false alarms. So the classic smoke alarm goes off every time a toast is toasted.

Fire alarm

The second type uses optical sensors that detect smoke and sound an alarm when it enters the sensor chamber. These can quickly spot smoldering fires that produce a lot of smoke — which happens when upholstery and soft furniture get caught — but are less sensitive to other types of fires. However, the difference isn’t huge, and they’re less likely to accidentally catch fire while cooking.

As a rule of thumb, it’s best to use visual alarms in living rooms or downstairs hallways, where there is a lot of upholstery and soft furniture, or where the alarm may be triggered by cooking fumes. Maintain ionization alarms for upstairs hallways or areas where dust or exposure to elements (such as from an open door) could trigger an optical sensor. When in doubt, handle visually or use multi-sensor alerts. Many fire departments generally discourage the use of ionization detectors, and some manufacturers have now discontinued their ionization products.

The fire brigade also recommends installing heat detectors in kitchens, garages, or workshops. They detect hot air instead of smoke and trigger when the air in the sensor chamber reaches a certain temperature (usually 58°C). Heat detectors are slower to respond than real smoke detectors, but are also less prone to false alarms. They won’t ring when you’re grilling sausages or grilling toast, but they’ll still warn you in time if your kitchen catches fire.

Different makes and models will be slower or faster at detecting smoke and will have different sirens operating at different volumes. Some even feature voice alerts or strobe lights. However, all detectors sold in the UK must comply with BS EN 14604:2005, which sets out requirements, testing, and performance standards for smoke detectors using optical or ionizing sensors. Heat detectors follow a separate standard BS 5446-3:2003.

How about the power supply

Wireless detectors normally use batteries and this element used to be the weak link in most home smoke alarms, needing to be replaced every year or so and often running out, causing the low battery alarm to go off in the middle of the night. As with carbon monoxide detectors, the trend is to use detectors with built-in 10-year lithium batteries, designed to extend the useful life of the detectors. In Scotland, these are now required by law. However, in England and Wales, you can still buy and use sirens with removable 9v batteries, and these are usually cheaper. We recommend paying extra for convenience and safety, but the choice is yours.
