Combined Alarms with Multiple Sensors

Combined smoke alarms contain multiple sensor types (heat detection, optical smoke detection and carbon monoxide detection) generally reducing the amount of detectors needed. Some combination smoke alarms also reduce the risk of false alarming or increase the speed of fire detection.
