FIRE SENSOR SETTING SYSTEM

PROBLEM TO BE SOLVED: To obtain a fire sensor setting system capable of setting a threshold used for detecting occurrence of a fire without providing a dip switch.SOLUTION: There is provided a system comprising a fire sensor connected to a two-wire sensor line and a setting device connected to the fire sensor. The fire sensor comprises a storage unit for storing plural kinds of thresholds that are compared with a detection value; and a control unit for outputting a fire signal, when detecting occurrence of a fire, based on comparing the detection value with any of the plural kinds of the thresholds that are stored in the storage unit. The setting device comprises a connection unit for inputting a signal to the fire sensor, that is attachably and detachably connected to the fire sensor; and a first operation unit. The setting device inputs the signal to the fire sensor via the connection unit, based on an input to the first operation unit; and the fire sensor selects a threshold with which the control unit compares the detection value among the plural kinds of the thresholds that are stored in the storage unit, based on the signal from the setting device based on the input to the first operation unit.SELECTED DRAWING: Figure 1 【課題】ディップスイッチを設けることなく、火災の発生の検出に用いられる閾値の設定を行うことができる火災感知器の設定システムを得る。【解決手段】２線式の感知器回線に接続される火災感知器及び火災感知器と接続される設定器とを備えたシステムであって、火災感知器は、検出値と比較される複数種類の閾値を記憶する記憶部と、記憶部に記憶された複数種類の閾値のいずれかと検出値との比較に基づいて、火災の発生を検出した場合に、火災信号を出力する制御部とを備え、設定器は、火災感知器に着脱可能に接続され、火災感知器に信号を入力する接続部と、第１操作部とを備え、設定器は、第１操作部への入力に基づいて、接続部を介して火災感知器に信号を入力し、火災感知器は、第１操作部への入力に基づく設定器からの信号に基づいて、記憶部に記憶された複数種類の閾値のうち、制御部が検出値と比較する閾値を選択する。【選択図】図１
