FAQ
What type of batteries do these alarms use?
The FireAngel Smoke & Carbon Monoxide Alarms utilise long-life 9V batteries. These typically last around 6-10 years, depending on usage and environmental factors. It’s important to replace them before the low battery warning activates.
Are these alarms suitable for flats?

How do I test the alarms?
To test the alarms, press the 'Test' button located on the front of the device. This will activate both the smoke and carbon monoxide detectors, and you should hear an audible alarm sound. Ensure you test regularly – at least once a month.
