To prevent the malfunction of an operation button for starting the guard of a guard area on an operation display panel and the forgetting of the operation of the operation button for canceling the guard at the time of the patrol of the guard area inside a building by turning the array of a guard start button and a guard cancellation button for inputting the command of guard cancellation to a different position and inscribing a guide line for indicating an operation order between the arrayed respective operation buttons.
Number input buttons 41 and 42 and the guard start button 43 and the guard cancellation button 44 operated after the input operation of the number input buttons 41 and 42 are arrayed at different levels and the buttons 41-44 are connected by the guide lines L1-L3. Since a resident just tracks the guide lines L1-L3 and performs the operations, an operation procedure among the number input buttons 41 and 42, the guard start button 43 and the guard cancellation button 44 is easily understandable. Thus, even when the operation method of the respective operation buttons 41-44 of an operation part 4 is forgotten, it is easily remembered and the malfunction of the operation buttons 43 and 44 after the input operation of the number input buttons 41 and 42 and the forgetting of the operation are prevented.
