When data of EEPROM storing set data such as interlocking data representing the interlocking relation between a fire sensor and an appliance to be controlled, correspondence data between the address of each terminal and an installation position of each terminal, display data displayed at a display portion of a fire receiver, reception function data representing the functions of the fire receiver, etc, are updated, the fire receiver of the present invention uses a memory pack which consists of an IC card, etc, and can be removably connected to the fire receiver, connects the memory pack storing data for updating the data to the receiver and reads the data and writes it to the EEPROM. Further, the set data before updating, that are stored in the EEPROM, are read into the memory pack, and this memory pack is carried to a service center, etc, so that set data for updating can be generated in consideration of the set data before updating, and are similarly written into the EEPROM through the memory pack. In this way, even those who have no knowledge on the ROM, that is, electronic circuits, can appropriately update the set data. Moreover, the updating operation is easy. The present invention provides such a fire alarm receiver and a fire alarm system. |
