If you've got areas in your home where smoke alarms just don't work – like kitchens, garages, or boiler rooms – this heat alarm is exactly what you need.

It's a fixed temperature heat detector that triggers when the surrounding air hits somewhere between 55°C and 65°C (that's about 131°F to 149°F).

It's rated A1 level, which is the standard for residential heat detection.

The built-in 85dB siren is loud enough to wake you up or get your attention in an emergency, even if you're in another room.

Powered by a built-in 1400mAh lithium battery that's rated to last about 5 years, it also gives you a 30-day low battery warning so you're never caught off guard.

The thermistor sensor is accurate and stable, and there's a test button to make sure everything's working.

Just a heads-up – this detects heat, not smoke or gas, so it's meant to complement your smoke alarms, not replace them.

Don't install it on escape routes, but for high-fume, dusty areas?
