PROBLEM TO BE SOLVED: To provide a fire receiver with a high maintainability, in which even a worker having no technical knowledge can check conditions of a substrate and essential parts of the fire receiver by execution from a menu. SOLUTION: The fire receiver comprises an input means for inputting an instruction to self-diagnose the fire receiver, a control means for self-diagnosing the fire receiver, and a display means for displaying the result of self-diagnosing the fire receiver. The self-diagnosis is at least one of a substrate voltage diagnosis for checking the voltage of each substrate in the fire receiver, a substrate connection diagnosis for checking whether a substrate having no microcomputer is connected to the fire receiver or not, a history list usage diagnosis for checking the memory usage of a history list in a main control unit, and a CRC value diagnosis for checking CRC value.
