About this deal

Like any battery-powered smoke detector, you should replace the batteries every 6 months (and sooner if the low battery alert sounds). While a front-facing battery compartment would make it easier to change out the batteries, the rear battery door wasn’t overly challenging to access. We like the fact that the battery compartment won’t close unless the batteries are correctly installed, providing a safeguard against improper battery placement and a unit that won’t power up. Batteries used to be the weakness of most household smoke alarms, requiring replacement every year or so and usually running out of charge, causing the low battery alarm to ring, in the middle of the night. As with carbon monoxide alarms, the trend is now towards alarms with a built-in, 10-year lithium battery, designed to work for the alarm’s effective lifespan. In Scotland, these are now a legal requirement. In England and Wales, however, you can still buy and use alarms with a replaceable 9V battery, and these often work out cheaper. We’d recommend paying extra for the convenience and peace of mind, but the choice is yours. Is there anything else worth looking out for? Any fire detection system, be it a smoke alarm, heat alarm or combination alarm, MUST be installed on the ceiling. For kitchen, garage or workshop use, fire services also recommend fitting a heat alarm. These sense hot air rather than smoke, and trigger when the air in the sensor chamber reaches a specific temperature, which is usually 58°C. Heat alarms are slower to respond than actual smoke alarms, but they’re also not as prone to false alarms. They won’t go off when you’re grilling sausages or burning toast, but they still provide ample warning if something catches fire in your kitchen. Of course, it is entirely possible to get connected smoke alarms that hook up directly to your home network via Wi-Fi, or through a proprietary connection or a Zigbee or Z-Wave hub. The advantage with these is that they can warn you of a fire through an alarm or alert on your smartphone, and also, with some systems, trigger smart lighting to come on. How we test smoke alarms

All of the major manufacturers (Aico, FireAngel and Kidde) make smoke and heat alarms that will work in combination with one another and we have tested pairs of smoke and heat alarms from each of them. Interlinked smoke alarms will use the same optical or ionisation technology mentioned above, so, they're not a type of alarm in their own right. Wireless devices communicate with each other and other devices without the use of connecting wires. This can be through interlinking by radio or through wi-fi.First, a small, slow smouldering fire. Such a fire would not initially give off much heat, but would produce quite a bit of smoke. A smoke detector would detect this fire. Smoke detectors are relatively simple by design and usually rely on an audible alarm to grab your attention. But if you’re looking for more advanced monitoring, the Kidde Smart Smoke and Carbon Monoxide Alarm is the right choice.

These alarms are more sensitive to smaller particles of smoke produced by the flaming stage of fires than optical alarms, and more easily triggered by cooking – causing false alarms. This could be critical if you’re out when there’s a fire. All of the smart smoke alarms we've tested are optical models. Combination smoke and heat detectors are enrolled as 24-hour zones. This means that they can cause a fire alarm upon activating, regardless of whether the system is in an armed or disarmed state. This is important, as you will want to receive emergency help for a fire regardless of the current arming state. If you are at home sleeping with your system disarmed, a fire alarm can occur. A fire alarm can also occur if you are away from home with the system armed. Either way, your system will take appropriate action. Ionisation alarms ionise the air between two electrodes. These are positively and negatively charged, creating a small current inside the chamber.On a lighter note, Google’s data also revealed that the day when smoke alarms are most likely to sound in the UK is pancake day. Is the Nest Protect smoke and CO alarm suitable for homes in Scotland now that the law has changed? Different makes and models will be slower or faster to detect smoke coming through and have different alarms working at different volumes. Some even feature voice alarms or strobing lights. However, any alarms sold in the UK have to meet BS EN 14604:2005, which specifies the requirements, tests and performance criteria for smoke alarms using optical or ionisation sensors. Heat alarms are governed by the separate BS 5446-3:2003 standard. Battery-operated smoke detectors have a compartment for a battery that serves as the power source for the device. Battery type and quantity vary by device, but two AA batteries or one 9V battery are the most common options. However, some devices require even more batteries, like the popular Google Nest Protect. It needs six AA batteries to perform its long list of features. Plan to change the batteries in your smoke detector every six months unless the unit has a long-lasting lithium-ion battery. These battery-operated smoke detectors may not need a battery swap for the entire 10-year life of the unit.

With a linked alarm, all alarms are activated simultaneously, giving you and your family potentially life saving extra time to get out of the building. Smart smoke alarms are designed to sound the alarm when they detect smoke, as a conventional smoke alarm would. But the unique selling point of a smart smoke alarm is the ability to send alerts to your phone when there’s a fire. A smoke detector can save your life. These small devices mount to the wall or ceiling and use a sensor to continuously monitor for conditions that indicate a fire. Smoke detectors are a must for virtually every room in your home and should be replaced every 10 years, according to the National Fire Protection Association (NFPA). A smoke and heat combination detector is called a smoke and heat detector. These sensors combine the functionality of a smoke detector and a heat detector. A combination smoke and heat detector will activate and trigger an alarm upon sensing either smoke or an unusually high temperature.Smart smoke alarms not only trigger the alarm in your home but also send an alert to your phone. Ideal if you are out, or on holiday. A combination smoke detector, like this version from Kidde, is built with sensors for detecting both smoke and carbon monoxide. We tested the Kidde Battery-Operated Smoke and Carbon Monoxide Alarm and recommend it for its simple installation and voice alerts, which clearly identify the trigger for the alarm event. It’s UL-certified and has a 10-year lifespan, although the two AA batteries will need more frequent replacement.
