FA3322 carbon monoxide alarm awarded Best Buy by Which?

FireAngel has been awarded a Which? Best Buy rating for its FA3322 Digital Display Carbon Monoxide alarm. The award was given in November 2024.

According to FireAngel, the FA3322 was designed for use in bedrooms and living spaces, providing audible and visual warnings if carbon monoxide, temperature or humidity levels become dangerous.

The device includes a digital screen which displays CO levels, temperature, and humidity, alongside written alerts.

FireAngel confirmed that the FA3322 includes a sealed battery with a 10-year lifespan and two separate test functions.

One function provides a quieter sound to confirm device operation, while the other simulates the full-volume alert for emergency use.

FA3322 features visual alerts and long-life battery

The FA3322 includes a real-time operating system, which FireAngel said was a first for its alarm products.

An employee at FireAngel said: “Four teams across the business worked together to design and build the FA3322 with the purpose keeping homeowners safe and providing them with peace of mind.

“This alarm is the first FireAngel alarm to use our real time operating system which makes the device so easy to use for the homeowner.”

The same source added: “The teams worked tirelessly to perfect and test the FA3322 to make sure the CO sensing, sound output level, display and functionality are top quality and are fully compliant with the highest safety standards.

“We are proud to have received this recognition from Which? after the hard work that all of our team put into it.”

Other FireAngel devices also recognised in the Which? review

Two additional FireAngel alarms were recognised during the same Which? product review.

The FireAngel FA3820 was described as a premium model and recognised for its ability to detect CO at all levels, including low but hazardous concentrations.

The FireAngel FA3313 was described by the Which? review team as a cost-effective option that delivered sufficient volume during alert conditions.

All three products reviewed were made available in the UK

The FA3322, FA3820 and FA3313 are all available to consumers in the United Kingdom.

Each device is designed to provide CO detection and has been manufactured by FireAngel Safety Technology.
