Combined Alarms with Multiple Sensors

Combined smoke alarms combine multiple sensor types (heat detection, optical smoke detection and carbon monoxide detection) creating rapid acting and fail-proof multi-sensor smoke detectors to help reduce false alarms whilst giving the earliest warning of a fire. Combining more than one detection type within a single unit can reduce the amount of units needed to be installed. However, if you are looking for an alarm for the kitchen a dedicated heat alarm (only) should be used.
