Abstract (en)
[origin: CA2796500A1] The invention relates to a fire detector (20 to 25) for monitoring a room and for triggering a fire alarm, having a smoke sensor (2) and a temperature sensor (3), wherein a smoke density can be measured by the smoke sensor (2) and a temperature can be measured by the temperature sensor, wherein when a temperature threshold value is exceeded and/or a smoke density threshold value is exceeded an alarm can be triggered, wherein the temperature threshold value is dependent on the smoke density and/or the smoke density threshold value is dependent on the temperature, wherein the fire detector (20 to 25) comprises a memory (10). A complicated evaluation as to whether the temperature threshold value or smoke density threshold value has been exceeded is avoided and the risk of false alarms is reduced as a result of the fact that a matrix is filed in the memory (10), wherein the matrix contains combination values, wherein by means of the matrix one of the combination values can be assigned to the measured temperature and the measured smoke density, wherein the combination value indicates whether the temperature threshold value and/or the smoke density threshold value has been exceeded or fallen below.
