PURPOSE: To provide the crime prevention display system where only an interlocking data ROM is changed even when the interlocking data content of a crime prevention receiver are altered.

CONSTITUTION: Once a reception part 3 receives a signal regarding crime prevention such as a fire smoke prevention discharging control signal, and various alarm signals through a signal line 12, the CPU 2 of the crime prevention receiver 1 reads interlocking data on the building number, floor, and are of a building corresponding to the received signal out of an association data ROM 4 and sets them in a communication control part 6. Further, the CPU 2 reads message data corresponding to the read interlocking data out of an interlocking data ROM 4 and sets them in the communication control part 6. The communication control part 6 sends the set interlocking data and message data to a crime prevention display device 5. The crime prevention display device 5 displays the interlocking data on the bilding number, floor, and area and message data received through the communication control part 11 at a display unit 9 as they are under the control of a CPU 8.
