Wireless Interlinked Smoke and Heat Alarm Scotland Bundle with 10 Year Battery Life, EN14604, CE Certified, Fire Alarms Scotland Interlinked, Low-Battery Alert, Pre Linked. 3 Pack

Product Information

Pros: Good for bedrooms, landings and hallways, and near to kitchens as they aren’t as prone to false alarms from cooking.

If you buy a battery-powered smoke alarm (rather than a mains-powered one), you'll need to decide whether you want one with a replaceable 9V battery, or sealed fixed-life batteryHeat (thermal) alarms detect heat (hot air) instead of smoke. The alarm is triggered when the temperature within the sensor chamber reaches over 58 degrees Celsius – generally when a fire is well established. Interlinking when one alarm goes off, all the connected detectors are activated. This can be particularly useful in a larger house. Complaint with Scottish & English Regulations - 100% compliant with the new Scotland Regs (Feb 22) & England Regs (Oct 22). Certified to BS EN14604:2005, BS 5446-2:2003 & British Kitemark EN 50291-1 standards Their distinguishing feature is the fact that they can be linked to other alarms, both heat and smoke alarms, so that when one senses danger they all sound. Cutting Edge Technology – Our smoke alarms use the latest photoelectric sensor and our heat alarms utilise an ultra sensitive temperature sensor

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. Smoke particles change the balance of the current. When this happens a signal is sent to the integrated circuit and the alarm sounds. 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. 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?

The latter are pricier when you buy for the first time, but you won't have to factor in the expense of replacement battery costs. 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. 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.
