Combined Alarms with Multiple Sensors
Combined alarms contain multiple sensor types, including heat detection, optical smoke detection, and carbon monoxide detection. In this category, you will find a range of alarms with a number of variations, such as smoke & heat sensors, smoke & carbon monoxide detectors, and heat & CO alarms.
Generally, these types of alarms help to reduce the number of detectors required throughout your home, streamlining your weekly testing and end-of-life replacements. With the combination of multiple sensors in one alarm, detection technology becomes more advanced, reducing the risk of false alarms, or even increasing the speed that fire or carbon monoxide is detected.
Some versions of combined alarms are mains powered with a back-up battery, providing fire and CO coverage at all times. Additional capability of being hardwire interlinked, or even radio-interlink, provides the earliest possible warning to one or even two risks.

Combined Alarms with Multiple Sensors
Improving Fire & CO Detection in my Home
Combined Alarms with Multiple Sensors
Combined alarms provide additional smoke, heat, and carbon monoxide detection through multiple sensors. These combination alarms usually have different alarm sounds, especially when detecting for two different dangers such as fire and carbon monoxide (including voice alert warnings) to inform occupants of the type of danger that has been detected. Combined sensor alarms are available in a range of configurations, including:
- Optical smoke detectors with heat detection
- Optical smoke detectors with carbon monoxide (CO) detection
- Heat detectors with carbon monoxide (CO) detection
Different combined sensor alarms are best suited to different areas of the home. For example, heat and CO alarms are great for kitchens and garages, reducing false alarms from dust and steam which may trigger optical alarms, while providing carbon monoxide detection. Smoke and heat detectors are suitable for kitchen diner rooms (but not directly over the kitchen area) where no fuel burning appliance is installed, while smoke and CO alarms are suitable throughout the home, apart from in kitchens, garages, and unoccupied loft spaces.
Combination alarms are also available in battery powered and mains powered variants, with radio-interlink technology and hard-wire options. This allows combined alarms to fulfil the highest levels of home protection. If you’re struggling to find the best detector for your needs, use our handy filter system for this category page, or contact our friendly customer support team on 0800 612 6537 for further advice.
Improving Fire & CO Detection in my Home
There are lots of things you can do to improve fire safety in your house. Fitting working smoke and heat alarms throughout your home is the best way to protect your family, while testing these regularly is just as important. Installing combination alarms which includes carbon monoxide detection further protects your family from dangers within the home.
Other steps to prevent fires, amd slow the spread of fire if one does start can also keep your family safe. For example, by keeping doors shut at night, even if they are not fire doors, they will act as a barrier to slow the spread of flames throughout the home by a few minutes, increasing time for your family to safely escape. This is particularly important for doors providing access to the kitchen, as this is where fires are most likely to start.
The best way to prevent fires in the home is to be aware of fire risks, and to reduce these wherever possible. For example, homes which are particularly cluttered, have deep fat fryers, or where residents smoke have an increased fire risk. To find out more about the fire risks in your home, use our Home Fire Safety Check tool. This quick questionnaire will identify the fire risks in your home, and give personalised tips on improving fire safety.
