ABSTRACT:
When updating the data of an EEPROM, wherein set data such as interlock data showing the interlock relationship between fire detectors and controlled equipment, data on correspondence between terminal addresses and places where the terminals are installed, display data to be shown on a display unit of the fire protection receiver, and receiver function data showing the functions of the fire protection receiver is stored, a fire protection receiver according to the present invention employs a memory pack comprised of an IC card or the like, which is disconnectably attached to the fire protection receiver, connects a memory pack, which stores data for updating set data, into the receiver, reads it, and writes it to the EEPROM. Alternatively, set data before updating stored in the EEPROM may be read into the memory pack, which is carried to a service center or the like, where set data for updating is created, referring to the set data before updating, and the created set data for updating may be written into the EEPROM via the memory pack in a similar manner. This makes it possible to provide a fire protection receiver and a fire protection receiver system, which enable a person, who does not know about a ROM, i.e., an electronic circuit, to update set data securely and which permits easy updating.
