Heat Detectors & Alarms

Heat alarms are specifically designed for areas where traditional smoke alarms may trigger false alerts due to steam, dust, or cooking fumes, such as in your kitchen, garage, or utility room. By detecting heat rather than particles in the air, these alarms offer dependable fire detection where smoke alarms might not be suitable.

Unlike smoke alarms, heat alarms respond to temperature changes instead of particles. This makes them ideal for installation in rooms with fluctuating air quality. Our collection includes both wireless heat detectors and mains-powered models, along with interlinkable alarms that can communicate with your smoke and carbon monoxide detectors. This integrated setup enhances your home’s fire safety by ensuring that all alarms sound at once in the event of a fire.

How Does A Heat Alarm Work?

A heat alarm works by detecting a rise in temperature, rather than smoke particles. Most models are triggered when the temperature reaches a fixed point — typically between 57°C and 88°C — though some may detect rapid temperature increases as well. These alarms are especially useful in environments where cooking fumes, dust, or steam could trigger false alarms on a smoke detector. 


Why Should I Have A Heat Alarm In My Kitchen?

Installing a heat alarm for the kitchen ensures reliable fire detection without the nuisance of false alerts from everyday cooking activities. Heat alarms are not affected by steam or smoke from cooking, making them a safer choice for busy kitchens. 

To get the most out of your heat alarm installation, it should be positioned according to the manufacturer’s guidelines, usually on the ceiling above or near a potential heat source.


What Temperature Does A Heat Alarm Go Off?

Most heat detector alarms are designed to activate when the room temperature rises to around 57°C to 88°C. The exact threshold varies depending on the model, so always refer to the Technical Specifications to confirm when your specific alarm will trigger.


Do I Need A Heat Alarm or A Smoke Alarm?

The answer is: both. A heat detector for the garage or kitchen is ideal because it won’t react to dust, fumes, or humidity, which might cause a smoke alarm to go off unnecessarily. However, smoke alarms remain crucial for areas like hallways, bedrooms, and living rooms, where early detection of smoke can be lifesaving.

A complete fire protection system includes heat alarms, smoke alarms, and carbon monoxide detectors, all working together, ideally through an interlinked system. At Fire Protection Online, we offer a full range of options to suit every room in your home and ensure maximum safety.
