PROBLEM TO BE SOLVED: To provide fire alarm equipment which easily discovers a terminal device to which addresses are double imparted, ,when address overlapping is discriminated in an ordinary monitoring state. SOLUTION: A fire receiver includes: a transmission circuit which performs signal transmission based on an address with each terminal device; a control means which discriminates an address from which there are a plurality of erroneous responses as an overlapping address when it is recognized that there are a plurality of times of erroneous signal responses, and displays the overlapping address on a display means; and an address designating means for designating an address. The control means is a means for transmitting a lighting signal from the transmission circuit, the lighting signal being transmitted for turning on an indicator lamp of the terminal device to which the designated overlapping address is imparted, when the overlapping address being displayed on the display means is designated through the address designating means, and the terminal device includes an indicator lamp lighting means for turning on the indicator lamp by receiving the lighting signal corresponding to the address imparted to the terminal device itself.
