HiSPEC Smoke Alarms Heat Detectors and CO Detectors Fire Safety Kits: Fully Compliant to 2022 Scottish Legislation (2 Smoke / 1 Heat)

Product Information

electrochemical. The advantage of this type of sensor is that it allows not only detecting smoke but also measuring the concentration of gasses, which makes them absolutely a must for private houses and other premises that use the gas heating system. You can put them in kitchens and garages because they’re not prone to false alarms from cooking or exhaust fumes. But they are slower to respond than smoke alarms. Most people will not experience any symptoms from prolonged exposure to CO levels of under, say, 40ppm. It depends on the length of exposure, but the real danger level starts at around 400ppm (two to three hours of exposure at this level can be life-threatening). To give you some idea of how dangerous higher levels of concentration can be, 1,500ppm could result in death within an hour and 6,000ppm within 15 minutes. An interesting by-product of the new breed of smart alarms is the fire-related data being collected, as is the case with Google, which makes the Nest Protect smoke and CO alarm. Google told us that it uses data from its alarms to provide ‘meaningful insights’ for its customers and to improve the product.

The one downside with this model is that it runs off a pair of AA batteries, which need to be switched out roughly every three years, making three changes during its lifespan. This isn’t a huge issue, but it means this model isn’t suitable for use in Scottish homes. It is, however, suitable for use in a boat or caravan, making it a good option if you need an alarm on your next boating or caravanning trip.Not as smart as a lot of other smart devices, but they may still come in handy if you like to be kept up to date. Thankfully, there’s an early-warning solution in the form of a carbon monoxide alarm that costs only a few pounds more than a smoke alarm. Be aware, though, that not all CO detectors are sensitive enough and some no-name brands are downright useless – and, therefore, dangerous. Ensure you opt for a reputable brand such as FireAngel, First Alert, Kidde, Nest or Lifesaver. When the battery is low, it starts a 30 day long low battery indicator. A short acoustic beep will sound when the voltage is below 2.85V. This gives you plenty of time to act, without leaving you in the dark at the last minute meaning you have to rush out to the shops immediately. It also leaves enough power in the battery for four minutes of alarm, which should be enough to get everybody out of the house.

Nest Home is one of the best smart home systems available, with a huge range of heating and lighting support available. Their Smoke and Carbon Monoxide Alarm is a must-have in the collection. Since 2002, Hispec has been at the forefront of delivering top-notch fire safety products and innovative lighting solutions to the UK wholesale market. Our diverse product streams cover Fire & CO alarms, Emergency Lightingand an extensive range of lighting products. They are big in America though, so watch this space for smart fire and smoke alarms becoming the norm here too. Extra Functionality Carbon monoxide sensors have a finite lifespan of between five and seven years, although a few manufacturers now claim that their sensors will last a full ten years. Generally speaking, it’s worth playing it safe and replacing your alarm a year or two before its life is supposed to run out. Tests in the US have shown that alarms over eight years old can fail to detect CO at levels of above 400ppm. As of February 2022, the Nest protect smoke and CO alarm no longer meet the requirements of the new Scottish alarm laws. This is because, while it can be linked to other Nest alarms, it has no way of detecting heat rises or of being linked to another heat alarm.

Testing is done manually by a simple press and hold of the large central button. Visual test red light flashes also go off around every 30 or so seconds, so if you feel you’ve gone a little while without seeing the light, you know you have to act. Using dual detection technology, photoelectric smoke and differential heat sensors, this Eve Smoke adds an extra layer of safety to your home.
