Patent ID: 6975237

Claim:
A detection system capable of detecting at least one hazardous condition, wherein the system is adapted for operation in an enclosure including a ventilation system, wherein the ventilation system is capable of operating in an on mode whereby the ventilation system at least partially permits air to pass through the enclosure, and an off mode whereby the ventilation system at least partially prohibits air from passing through the enclosure, said system comprising: at least one detector capable of detecting at least one level representative of the severity of the at least one hazardous condition within the enclosure, wherein each level representative of the severity of the at least one hazardous condition is associated with a pre-alarm threshold and an alarm threshold that is higher than the pre-alarm threshold; and a controller electrically connected to the at least one detector and the ventilation system of the enclosure, wherein the controller is capable of operating the ventilation system in the off mode when at least one level detected by the at least one detector is above the respective pre-alarm threshold, and wherein the controller is capable of reporting at least one respective hazardous condition when at least one level detected by the at least one detector is above the respective alarm threshold.
