What to know\nThe FA6720-R is a heat detector designed for kitchens, attics, garages, caravans and other spaces where dust or humidity can set off traditional smoke alarms. It focuses on detecting heat rather than smoke, which helps minimise false alarms from cooking fumes while still providing early warning in a fire. This model uses a 10 year sealed for life battery, so replacement batteries aren’t part of the daily maintenance, subject to the product’s warranty period.\n\n## Technical details\nThis heat alarm is CE and UKCA marked and certified to BS 5446-2:2003, KM 694292, making it suitable for domestic properties and leisure accommodation vehicles. It ships with a 5 year warranty and includes a silence button to mute false alerts, a low battery warning for safety, and a quiet test function to verify operation without creating a disturbance. The baseplate is removable and compatible with the HT-630 model, which makes swapping units quicker and easier when required.\n\n## How it fits into a safety setup\nIf you’re building or updating a kitchen safety profile, this heat alarm can pair with other FireAngel devices such as smoke and carbon monoxide alarms for a layered approach. The product recommendation suggests pairing with a fire blanket for added kitchen protection.\n\n## What stands out\nOn the plus side, the silent alert and discreet test feature support practical daily use in busy living spaces. The 10 year sealed battery reduces maintenance frequency, which is appealing for low-upkeep installations.\n\n## Where it may fall short\nIt’s specifically a heat detector, so if you need broad smoke detection or multi-sensor protection in a single unit, you’ll want to consider complementary devices. The warranty is five years, which is reasonable, but may not align with longer-term expectations in some households.\n\n## Who it’s for\nIdeal for kitchens and other dusty or humid spaces where smoke alarms may produce nuisance alarms, as well as domestic properties and leisure accommodation vehicles that require BS 5446-2:2003 certified heat detection.\n\n## Before you buy\nCheck that the baseplate fits your mounting setup and that you are comfortable operating the mute button for false alarms. Confirm that your overall safety plan includes a mix of heat and smoke alarms suitable for your property.\n\n## Practical usage example\nIn a kitchen with frequent cooking steam, you might set this FA6720-R as part of a dedicated safety cluster, leveraging its heat-only detection to avoid constant nuisance alerts while still providing timely warning when heat thresholds are reached.\n\n## FAQ\nQ: How long does the battery last? A: It uses a 10 year sealed for life battery.\nQ: Can I replace just the unit if it fails? A: The baseplate is designed for easy replacement, the unit is intended to be swapped with a compatible model like HT-630.\nQ: Is it suitable for caravans? A: Yes, it is described as suitable for domestic properties and leisure accommodation vehicles.\n\n## Should you buy it?\nWorth considering if you prioritise a low-maintenance heat alarm for kitchens or humid spaces, and you want certification and a straightforward swap for an existing HT-630 base. It might not be the best choice if you need broad smoke detection or a longer-term multi-sensor solution in one device.
