Embodiment Construction

[0018] figure 2 A number of fire monitors 20, 21, 22, 23, 24 and 25 are shown. The fire detectors 20 , 21 , 22 , 23 , 24 and 25 are identical in particular in terms of construction. exist figure 2 Six fire detectors 20 to 25 are shown in . However, the number of fire detectors 20 to 25 can also be less than six or more than six.

[0019] Fire detectors 20 to 25 are used to monitor rooms (not described in detail) and to trigger fire alarms. Fire detectors 20 to 25 are designed in particular to trigger a fire alarm. For monitoring a fire, these fire detectors 20 to 25 are preferably, but not necessarily, installed in the middle of the ceiling of the room to be monitored.

[0020] With the help of figure 1 The main components of the fire detectors 20 to 25 are explained:

[0021] Each of the fire detectors 20 to 25 described herein preferably has a housing and a circuit board (not shown).

[0022] The fire detectors 20 to 25 preferably each have a controller 1 . The co...

Abstract

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.

Description

technical field [0001] The invention relates to a fire detector for monitoring a room and triggering a fire alarm, which has a smoke sensor and a temperature sensor, wherein the smoke concentration can be measured by means of the smoke sensor and the temperature can be measured by means of the temperature sensor, wherein when a temperature threshold is exceeded and Or an alarm can be triggered when a smoke density threshold is exceeded, wherein the temperature threshold is dependent on smoke density and / or the smoke density threshold is temperature dependent, wherein the fire detector has a memory. Background technique [0002] Fire detectors are known in the prior art, which measure the smoke concentration and issue an audible alarm for a specified time period when it exceeds a preset measured value, as well as fire detectors which In addition, the wireless alarm is moved to the adjacent fire detector, which itself emits an audible alarm, and fire detectors are also known w...
