X-Sense XH02-M heat alarm 7-year battery

The XH02-M is a wireless heat alarm that links to the SBS50 base station to extend home protection without extra wiring. It senses rapid temperature rises and steady high temperatures, so it reacts to fire risks while avoiding false triggers from cooking smoke. Set up is simple, press the test and silence button to pair each unit and add up to 50 devices for broader coverage.

Key features

This two-pack provides cost-free push notifications via the X-Sense Home Security app, so you can get alerts for alarms, low battery and faults wherever you are. The device sharing function lets household members receive notifications, view history and silence alarms through the app. The alarm emits an 85 dB tone at 10 feet 3 m, helping ensure the warning is heard across a typical house.

Why it makes sense

This model is a Class A1 heat alarm with an NTC thermistor that focuses on temperature rather than smoke, which reduces nuisance alarms from cooking or dust. It is CE marked and meets BS 5446-2:2003, which supports compliance with Scottish regulations when used as part of the Link+ series. Bear in mind the SBS50 base station is required for wireless interlinking and is sold separately.

Best use cases

If you need additional protection in kitchens, garages or boiler rooms where smoke alarms are likely to trigger falsely, the XH02-M is a practical choice. It’s a low-maintenance option thanks to the sealed 7-year battery and tamper-proof design. It suits homes where app notifications and shared access are useful for family members or carers.

Care & maintenance

Check the app for battery and fault alerts, and test each alarm regularly using the test button. Replace units after the manufacturer recommended service life even though the battery is sealed, according to regulatory guidance.
