A、 The smoke sensor in each detector monitors when the smoke density is above a previous limit. If the density keeps higher than the limit for about eight seconds, the sensor set the detector to the alarm condition.
B、 The smoke sensor in each detector monitors for smoke density above a preset limit. If the density stays above the limit for appropriately eight seconds, the sensor sets the detector to the alarm condition.
C、 The smoke transducer monitors for smoke density above a presumed limit of each detector. If the density remains over the limit about eight seconds, the transducer turn the detector to the alarm condition.
答案：B
