Document Type and Number:
Japanese Patent JP7040998
Kind Code:
B2
Abstract:
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
