1. Ionisation Alarms
Ionisation alarms are a type of smoke detector that uses a small amount of radioactive material to sense smoke. They are particularly effective at detecting fast-flaming fires, which can occur in homes. However, they are not the only type of alarm you should rely on.
How They Work
Ionisation alarms work by creating an electrical current that is disrupted when smoke enters the chamber. This disruption triggers the alarm. They are best suited for detecting fires that produce little visible smoke, such as those caused by flammable liquids or paper.

It’s crucial to have a mix of smoke alarms in your home for optimal safety. Ionisation alarms can provide an extra layer of protection, but they should not be your only line of defence.
Summary
In summary, ionisation alarms are a valuable addition to your home safety plan, especially for detecting fast-flaming fires. However, to ensure comprehensive fire safety, consider pairing them with other types of alarms, such as photoelectric smoke alarms, which are highly effective at detecting smouldering fires. This combination can help protect your home during the festive season fire safety risks, where cooking and decorations can increase fire hazards.
2. Photoelectric Alarms
Photoelectric alarms are designed to detect smoke using a light beam and a photo cell. When smoke enters the chamber, it scatters the light, triggering the alarm. These alarms are particularly effective at sensing smoky and smouldering fires, which are common in homes.
Key Features of Photoelectric Alarms
-
Fast Detection: They respond quickly to smouldering fires, often within three to five minutes.
-
Less Prone to Nuisance Alarms: Unlike ionisation alarms, they are less likely to go off due to cooking fumes. Additionally, photoelectric smoke alarms are particularly effective in detecting smoke from synthetic materials and minimizing false alarms.
-
Regular Maintenance Required: Dust and insects can cause false alarms, so regular cleaning is necessary.
