Fire alarms are an essential element of any building's safety system. They are designed to detect and alert occupants to the presence of a fire, providing valuable time to evacuate the building safely. There are several types of fire alarms available for both residential and commercial settings, each with its unique features and benefits.

Ionization Smoke Alarms

Ionization smoke alarms are the most common type of residential smoke alarm. They work by using a small amount of radioactive material to ionize the air inside the alarm. When smoke enters the alarm, it disrupts the ionization process, triggering the alarm.

Ionization smoke alarms are good at detecting fast-burning fires and are suitable for use in living areas, bedrooms, and hallways.

Photoelectric Smoke Alarms

Photoelectric smoke alarms use a light source and a light sensor to detect smoke particles. When smoke enters the alarm, it scatters the light beam, triggering the alarm. Photoelectric smoke alarms are good at detecting slow-burning fires and are suitable for use in kitchens, attics, and garages.

Some residential alarms combine ionization and photoelectric sensors into a single smoke alarm.

Heat Alarms

Heat alarms are designed to detect high temperatures and are ideal for use in areas where smoke alarms may be prone to false alarms, such as kitchens or garages. Heat alarms are available in fixed and rate-of-rise models. Fixed heat alarms detect a constant temperature, while rate-of-rise alarms detect a rapid increase in temperature.

Carbon Monoxide Alarms

Carbon monoxide alarms are designed to detect the presence of carbon monoxide gas, which is produced by the incomplete combustion of fuels such as gas, oil, and wood. Carbon monoxide is a silent killer, and exposure to high levels of the gas can cause serious health problems or death. 

Carbon monoxide alarms are should be in areas where fuel-burning appliances are present, such as kitchens, garages, and heating systems.

Manual Call Points

Manual call points, also known as break glass alarms, are designed to be activated manually in the event of a fire. They are typically located near exits and are used to trigger the fire alarm system. Manual call points are found in commercial settings, such as schools, hospitals, and office buildings.

Addressable Fire Alarms

Addressable fire alarms are designed for use in large buildings or complexes. These systems can monitor and control multiple fire alarm devices, such as smoke detectors, heat detectors, and manual call points, from a central control panel. 

Addressable fire alarms are ideal for use in commercial settings, such as hotels, shopping centers, and high-rise buildings.
