UK requires that a single sensor smoke sensor alarm must comply with the standard of BS EN 14604:2005, and a temperature sensor alarm must comply with the standard of BS 5446-2:2003. The multi-sensor fire alarm uses multiple built-in sensors to detect a wider range of fire categories, with the advantage of ensuring accuracy while reducing the risk of false alarms. During inspection and certification, multi-sensor fire alarms must meet the requirements of multiple standards.
Aico's multi-sensor fire alarm is conducted in accordance with the standards of BS EN 14604 (smoke alarm standard) and BS 5446-2 (high temperature alarm standard) and additional inspections of multiple other test fires have been carried out. This is why multiple product standards are marked next to the Kite Mark certification of Aico multi-sensor fire alarm, and it is also the unique feature of Aico products.
Aico multi-sensor fire alarm can only start the smoke alarm (comply with BS EN 14604:2005) or the temperature sensing alarm (comply with BS 5446-2:2003). But it can also intelligently activate two sensors to improve response speed and alarm accuracy for different fire categories, enabling this function by constantly changing heat levels in the air to activate different thresholds. This way the alarm can detect a wide range of fire categories more accurately and effectively reduce false alarms.
Multi-sensor fire alarm can be used anywhere a single-sensor smoke alarm (compliant with BS 5839:6-2019). Due to the accuracy of multi-sensor fire alarms in detecting a wide range of fire categories and their ability to effectively reduce false alarms, it becomes a must-have in some scenarios including but not limited to open kitchens, living areas, lounges and lofts. These places usually have no electronic equipment installed (compliant with the recommended standards of BS 5839:6-2019).
Aico multi-sensor fire alarm also uses dust compensation technology, which can enhance reliability in multiple scenarios and ensure continuous accuracy over a 10-year service life, reducing the risk of false alarms. Optical alarms and multi-sensor alarms can reduce the risk of false alarms immediately compared to ion alarms. However, both will also be disturbed by pollutants, which will affect their sensitivity. A recent survey conducted by BRE on the lifespan of smoke alarms found that the sensitivity of light alarms decreases as the alarm ages. Considering that most household alarms have a lifespan of 10 years and most alarms will not be cleaned in the middle, the accumulation of pollutants in the alarm has indeed become a big problem.
In order to further reduce false alarms and improve alarm accuracy, the Aico alarm uses dust compensation technology, that is, automatically compensates for pollutant interference generated by the alarm over time. It is achieved by using software that can continuously monitor and adjust the sensitivity of the trigger alarm, so as to ensure that the alarm can maintain the same sensitivity in the presence of pollutants accumulated. If the contaminants in the alarm reach an uncompensated level, the alarm will inform the residents through flashing amber LED lights and chirping. At this time, residents can use a vacuum cleaner to remove contaminants and debris in the alarm, and the software will automatically correct the sensitivity of the alarm.
alarms rarely reach the point where they require manual cleaning, but alarms without dust compensation technology may need to be replaced. Of course, it is more common that alarms without dust compensation technology will become more and more sensitive, thereby increasing the risk of false alarms. The Ei650 battery-powered photoinductor smoke alarm under
Aico, the photoinductor alarm powered by the Ei3000 main power supply and the multi-sensor alarm are all equipped with dust compensation technology. Now our users rely on this technology, and they also choose alarms equipped with this technology when selecting alarms to reduce the costs of replacing alarms, repairing alarms and using alarms under harsh conditions.
