Which smoke alarm should I get?Smoke Alarm London

For homeowners, you have the choice between battery-powered smoke alarms or mains-powered ones.  Since 2015, landlords must provide mains-powered or long-life battery-powered smoke alarms on every floor in their rental properties.  Mains-powered alarms can be interconnecting, which means that when one is triggered then all of them are activated.  This helps alert everyone to a fire in another part of your property

There are 4 main types of smoke detectors available and each lends itself to different areas of your home.

Ionization smoke alarms

These work by ionizing the air, creating a small current within the unit. When smoke particles change the balance of the current, the alarm goes off.

Good for: dusty areas, such as lofts and sheds, or areas near where people smoke.

Not so good for kitchens, or nearby areas, as it can trigger the alarm through the cooking heat/smoke.

Optical smoke alarms

These work by detecting smoke particles using an infrared LED.

Good for: bedrooms, living rooms, landings, and near kitchen areas, as they are less likely to be triggered by cooking.

Not so good for dusty areas or landings near bathrooms as they may be triggered by steam.

Heat alarms

These work by detecting a rise in temperature, rather than detecting smoke particles

Good for: Kitchens

Not so good for larger rooms as they only cover a small area.

If you have a smoke alarm that keeps going off, check which type of alarm it is as you may wish to consider buying a different type that is less likely to cause false alarms.

Smart smoke alarms

Most smart smoke alarms on the market are optical alarms but have the added feature of being able to alert you to a fire within your home.  The alarm will send an audible alarm to your smartphone and/or a text/email.

Smart alarms are also able to collect data about the incident of fire and smoke which can be used to improve the performance of alarms in the future. Some alarms have a steam check feature to reduce the level of false alarms from cooking/bathroom steam.

Where can I buy my smoke alarms?

You can obtain smoke alarms directly from Third Eye. We can install and connect them directly to your intruder alarm. This enables you to receive alerts direct to your smartphone if the smoke alarm is triggered.


How do I maintain my smoke alarm?

Battery-powered alarms may have a long-life battery which should last 10 years, after which time it should be replaced. Otherwise, you will need to test your alarm every 6-12 months and replace the battery annually. There’s little point in having it fitted and it not being in working condition when you need it. Studies show that the risk of death from fire is more than twice as high in houses where there is no working smoke alarm.

Mains-powered smoke alarms also require battery backup in case there is a power cut. If your smoke alarm is beeping, this indicates that the battery is low and should be replaced as soon as possible.Review 1
