A fire detection system (10) includes a plurality of smoke detectors (14) positioned for detection of smoke within one or more smoke detection volumes (12a, 12b). The fire detection system (10) is configured to monitor occupancy of the smoke detection volumes (12a, 12b) or to receive data indicative of occupancy of the smoke detection volumes (12a, 12b), for example from an intrusion detection system (20). The fire detection system (10) is configured to adjust a smoke sensitivity associated with each of the smoke detectors (14) based on the occupancy of the respective smoke detection volume (12a, 12b), with the smoke sensitivity being decreased when the respective smoke detection volume (12a, 12b) is occupied.
A method comprising adjusting a smoke sensitivity of a fire detection system based on occupancy of a smoke detection volume associated with the fire detection system, wherein occupancy of the smoke detection volume is detected using an ambient light sensor positioned to monitor the smoke detection volume, and wherein the ambient light sensor is configured to measure whether lights within the smoke detection volume are switched on or not.
A fire detection system comprising a smoke detector for detecting smoke within a smoke detection volume, wherein the fire detection system is configured to receive occupancy data indicative of occupancy of the smoke detection volume or monitor occupancy of the smoke detection volume, and to adjust a smoke sensitivity associated with the smoke detector based on the occupancy of the smoke detection volume, wherein the occupancy of the smoke detection volume is detected using an ambient light sensor positioned to monitor the smoke detection volume, and wherein the ambient light sensor is configured to measure whether lights within the smoke detection volume are switched on or not.
A method comprising adjusting a smoke sensitivity of a fire detection system based on occupancy of a smoke detection volume associated with the fire detection system, wherein occupancy of the smoke detection volume is detected using data received from a lighting control system of a building, and wherein the data is indicative of occupancy based on lights being turned on or off.
A fire detection system comprising a smoke detector for detecting smoke within a smoke detection volume, wherein the fire detection system is configured to receive occupancy data indicative of occupancy of the smoke detection volume or monitor occupancy of the smoke detection volume, and to adjust a smoke sensitivity associated with the smoke detector based on the occupancy of the smoke detection volume, wherein the occupancy of the smoke detection volume is detected using data received from a lighting control system of a building, and wherein the data is indicative of occupancy based on lights being turned on or off.
