Types of Smoke Detectors/Alarms

Optical smoke alarms are particularly good at detecting slow smouldering fires such as soft furnishings or electrical wiring.

Heat alarms are ideal for smokey and dusty environments, they react to heat instead of smoke so are less likely to give false alarms.

Multi-Sensor alarms contain two separate sensing elements – optical and heat allowing them to monitor two different by-products of fire. Because they monitor 2 different by products of fire, their response to all types of fire is significantly improved over singal sensor alarms.

Ionisation smoke alarms react quickly to fast flaming fires by detecting the change in ionised properties of air through smoke.

Mains-Powered Smoke Alarms


Mains powered alarms are the most reliable domestic and commercial smoke alarms as they run off your home or buildings main power supply. Once the Smoke alarm is correctly installed you will not have to test the battery regularly, although they do have a battery back up in the event that you have a power cut. These smoke alarms need to be installed by a qualified electrician.
