Our commitment to providing the highest quality products and service is second to none.

When lives rely on them, you cannot afford to take risks with your Smoke or Carbon Monoxide (CO) alarms. All our alarms are manufactured in the Ei Electronics factory in Shannon, Ireland – which has produced over 100 million alarms since the company was founded 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.

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 CO 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.


Every alarm is third party accredited to the relevant British or European standard.

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).

Both Aico and Ei Electronics also operate to recognised business operating standards in the manufacturing and distribution of all products:

  • ISO 9001:2015 quality management standards
  • ISO 14001:2015 environmental management standards
  • OHSAS 18001:2007 occupational health and safety management standards
