Different Types of Sensors

When choosing a smoke alarm for your home, it’s essential to understand the different types of sensors available. Each sensor type is designed to detect specific kinds of fires, providing optimal protection for various areas in your home.

Photoelectric sensors, also known as optical sensors, are particularly effective at detecting slow-burning, smouldering fires, such as those caused by upholstery or electrical wiring. These sensors use light beams to detect the presence of smoke particles in the air. Smoke from smouldering fires tends to be dense and produce larger particles, which are easier for photoelectric sensors to detect. Optical alarms with this technology are often recommended for installation in bedrooms and hallways.

Ionisation sensors are more effective at detecting fast-burning, flaming fires that produce small smoke particles, such as fires ignited by paper or curtains. These sensors use a small amount of radioactive material to ionise the air inside them, creating an electric current. When smoke particles enter the ionisation chamber, they disrupt this current, triggering the alarm. Ionisation alarms are best suited for areas where fires can spread rapidly, such as kitchens or storage rooms.

An electrochemical sensor is primarily used to detect carbon monoxide, a toxic gas produced by incomplete combustion in fires. Carbon monoxide can be released from various sources, such as malfunctioning gas appliances or blocked chimneys. Electrochemical sensors measure changes in the electrical properties of a chemical reaction when carbon monoxide is present. Although not specifically a smoke detection technology, carbon monoxide alarms are often combined with smoke alarms for added protection.

Heat alarms are designed to respond to rapid temperature increases, such as those caused by kitchen fires or flaming fires in garages or workshops. These alarms are not affected by smoke, which makes them less prone to false activations in areas with high levels of heat or steam, like kitchens and bathrooms. Heat alarms are an essential addition to an effective fire detection system, complementing smoke alarms to ensure all types of fires are detected swiftly and accurately.

In summary, a well-rounded fire protection system should include a combination of optical and ionisation alarms, as well as heat alarms and carbon monoxide detectors. By understanding the different types of sensors and their specific applications, you can better protect your home and family from the dangers of fire.
