FireAngel FA3820-EU Carbon Monoxide Alarm

FireAngel is a well-known British brand originally established in 1998 under the company Sprue Aegis plc, headquartered in Coventry, United Kingdom. The brand has built a strong reputation as a leader in home safety technology, supplying a significant portion of the UK's Fire and Rescue Services with smoke and carbon monoxide alarms.

While the brand's design and engineering are based in the UK, the physical manufacturing of its products, including the FA3820 series, is primarily centered in China. This is facilitated through its long-standing partnership and ultimate acquisition by Siterwell Electronics, a major Chinese manufacturer of high-tech sensors and alarms.

In 2024, FireAngel was officially acquired by Intelligent Safety Electronics, which is a subsidiary of Siterwell Electronics Co Ltd based in Ningbo, China. This transition moved the ultimate ownership to China, although the brand continues to maintain its R&D and significant operations in the United Kingdom to serve the European market.
