Summary:To make it possible to appropriately change data in consideration of the data changed by a receiver in operation when receiver data is changed.SOLUTION: A fire alarm system monitors a fire using receiver data 50, in which analog fire sensors 14 and terminals including interlocking devices are connected to transmission lines 12-1 to 12-3 that are pulled out of a receiver 10, and in which data of the terminals are memorized to the receiver 10 as the receiver data 50. The receiver data 50 can be changed in operation using a screen of a display 36. When the receiver data 50 is changed, a different data detection unit 52 compares update data 60 read out of a USB memory 56 and the receiver data 50 for the unit of a terminal so as to detect a pair of the update data and the receiver data different from each other, and a data changing unit 54 makes it possible to select either of the update data or the receiver data, which is different from each other, being displayed side by side on the screen of the display 36 and then changes the data to the selected update data or the receiver data.SELECTED DRAWING: Figure 1 【課題】受信機データを変更する場合に、運用中に受信機で変更されたデータを考慮した適切なデータ変更を可能とする。【解決手段】火災報知設備には、受信機10から引き出された伝送路12−1〜12−3にアナログ火災感知器14や連動機器を含む端末が接続され、受信機10に端末のデータが受信機データ50として記憶され、受信機データ50を用いて火災を監視する。受信機データ50は運用中にディスプレイ36の画面を使用して変更される場合がある。受信機データ50を変更する場合、相違データ検出部52は、USBメモリ56から読み込まれた更新データ60と受信機データ50を端末単位に比較して相違する更新データと受信機データの組を検出し、データ変更部54は、相違する更新データと受信機データを並べてディスプレイ36に画面表示して何れか一方の選択を可能とし、選択された更新データ又は受信機データに変更する。【選択図】図1
