Aico are committed to providing the highest quality smoke and Carbon Monoxide alarms designed to provide the most reliable life-saving detection.

As a wholly owned subsidiary of Ei Electronics, all alarms are manufactured at the Ei Electronics factory in Shannon, Ireland. Over 100 million alarms have been manufactured since the company began over 50 years ago.

Manufacturing Quality

During the manufacturing process, every single alarm is tested at multiple points to ensure consistent high quality across all products. These points include:

  • Initial Assembly – the individual components of the alarms are tested to ensure they meet strict tolerances
  • Test and Calibration – as part of the assembly process, alarms are tested and calibrated in smoke, heat or Carbon Monoxide to ensure they meet the relevant British/European standards. This means that they will respond quickly to whatever they are designed to detect
  • Final Test – once the alarm is fully assembled, it is again put through a thorough test. It is a final verification that the alarm is fully functional before being shipped from the factory


In addition to the high level of testing during the manufacturing process, every alarm is third party accredited to the relevant British or European standard to confirm the quality – look for the Kitemark shown on the alarms to demonstrate that the alarm has been accredited by BSI (British Standards Institute) or VdS mark to show it has been accredited by VdS (European Standard).
