Looking to buy Smoke Alarms?

Even if you're incredibly vigilant about turning off your gas hob or oven off, accidents and malfunctions can happen. That's why you need a smoke alarm or two to keep you safe. The first line of defence in any fire safety plan, a fire alarm is always on guard for a whiff of smoke - after all, there isn't any without fire!

Types of smoke alarm

There are many different types of smoke alarm designs to choose from. It used to be that ionisation smoke alarms were the preferred choice for landings and office spaces since they were more effective, but these days they're being phased out. This is because they're dangerous to manufacture, awkward to transport and hard to dispose of safely.

Nowadays, an optical smoke alarm is what all fire safety experts will recommend for the home. This technology, which uses infrared LEDs, has come on leaps and bounds in the last few years; almost all the fire alarms you'll see in this category use the optical system.

One choice that you can still make is between battery-powered wireless smoke detectors and a mains smoke alarm design. Most smoke alarms today are powered by batteries, meaning they can be placed just about anywhere in your home with very little effort. Of course the protection that a battery smoke alarm provides is only good as long as the battery holds charge. But all of the wireless alarms sold in this category will tell you very clearly when they're running out of power by beeping loudly over the course of several hours.

If you're a building specialist for a block of flats, you're a procurement officer for a multi-floored office building or you just have a large home, a set of interlinked smoke alarms will be an excellent choice. Interlinked means that if one alarm detects smoke, they all go off at the same time. This can be really important if you're a deep sleeper or have trouble with your hearing, as you might not hear an alarm sounding off downstairs.

Smoke alarm brands

You can buy smoke alarms from the biggest brands in this category. For instance, our sellers offer up a comprehensive selection of Aico smoke alarm products, including the Aico interlinked and wireless alarms plus Aico battery powered smoke alarms.

Smoke and heat alarms are only a part of good fire safety in the home or office. For other protective measures, make sure to browse our other fire safety supplies, including fire extinguishers, heat alarms and carbon monoxide alarms.
