The Mercury 350.130UK heat detector activates an alarm when it detects a sudden or extreme rise in temperature, rather than smoke. Its thermistor-based detection technology makes it suitable for areas with fumes or high humidity, such as kitchens, garages and attics, where it can help reduce false alarms caused by cooking fumes.

The built-in battery has a 10-year lifespan and is activated by a switch on the base. A low-battery warning indicates when the device is nearing the end of its lifespan, while the hush function silences the alarm for 9 minutes. The detector features automatic reset and has been tested at an approved laboratory for compliance with the BS 5446-2: 2003 standard.
