PURPOSE:To enable the presence or absence of a gas leakage alarm fitted to each terminal controller to be set on a central controller, by a method wherein operating switches corresponding to each terminal controller are utilized after switching the system condition from an operative or stopped state to an initialized state. CONSTITUTION:In a centralized supervisory device for air conditioner, one or a plurality of air conditioners 3 having the terminal controller 2 to be operated concurrently are provided in each of a plurality of rooms, and each of the terminal controllers 3 is centralizedly controlled by the central controller 1, 1a. In the device, each of the terminal controllers 2 is fitted with the gas leakage alarm, which the central controller 1, 1a is provided with respective operating switches 13 for commanding the operation or stoppage of the corresponding air conditioners 3 through the terminal controllers 2, and changeover switches for changing over the system to the operative, stopped or initialized state. The presence or absence of the gas leakage alarm fitted to each of the terminal controllers can be set on the central controller 1, 1a by operating the corresponding operating switch 13 in the condition wherein the changeover switch is changed over from the operating or stopping side to the initialized side. Accordingly, a setting operation is easy to perform, and possibility of danger in operations can be eliminated. |
