Heat Alarms

Heat alarms, also known as heat detectors, are designed for installation in smoky or dusty environments such as kitchens or garages. They will not 'false alarm' when exposed to cooking fumes or car exhaust emissions. This is because heat alarms work by detecting a rise in temperature rather than smoke particles in the atmosphere. Some heat detectors even measure the speed of the temperature rise.

We also offer a heat alarm specifically designed to monitor the area above a cooker to detect if an oven ring has been left on or a pan dries out (Stove Guard).

What Are Heat Alarms?

What Are Heat Alarms?

Heat alarms are designed for installation in smoky or dusty environments such as kitchens or garages, as they will not false fire alarm due to cooking fumes or emissions from a car exhaust. Heat alarms detect a rise in temperature beyond a trigger level and some heat alarms even measure the speed of the temperature rise. We also offer a heat alarm specifically designed to monitor the area above a cooker to detect if an oven ring has been left on or a pan dries out (innohome stove alarm).

Do I Need a Heat Alarm or Smoke Alarm?

Do I Need a Heat Alarm or Smoke Alarm?

Heat alarms are recommended for installing in kitchens and garages, where smoke or cooking fumes could cause false alarms in traditional smoke alarms. Heat alarms detect heat, rather than smoke, which makes them ideal for areas where dust, steam, and 'normal' smoke fumes (such as during cooking) are present, and would ordinarily cause a smoke alarm to falsely activate.

Smoke alarms are recommended for installing in most rooms of the house, including bedrooms, living rooms, and hallways (general living areas). Optical smoke alarms are designed to quickly detect smoke from all sources, and are also able to detect smoke from slower, smouldering fires.
