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.
Our range of combined alarms includes options suitable for the previous Building Regulations' requirement of Grade F (battery powered) or Grade D (mains powered) installations, but also comply with the 2019 update which splits them into according to the latest BS 5839 Part 6. Please see our guide to BS 5839-6: 2019 for more information on Grades of alarm.
