Designed for areas where smoke alarms often give false alerts, this heat alarm with a 10-Year sealed battery provides reliable protection by detecting rapid rises in temperature instead of smoke. It’s ideal for kitchens, garages, and lofts, places prone to fumes or steam, where traditional smoke alarms may be unsuitable.
Using advanced thermistor technology, it responds quickly to high temperatures caused by real fire risks, such as chip pan fires, without reacting to everyday cooking fumes. Manufactured by Mercury, with a sealed 10-year internal battery, there’s no need for battery changes. Simply activate it at the base, mount it using the included kit, and test it regularly.
Tested and approved to BS 5446-2: 2003 standards, the alarm also features a convenient test and mute button to silence it temporarily if needed. Low battery alerts near the end of its life ensure you know when to replace it, making this a simple, low-maintenance solution for long-term home safety. For full household protection, pair this with the optical smoke detector.
