To automate the inspection of a calling signal generation circuit in a slave unit for an elevator interphone.SOLUTION: A monitoring device (an inspection device) 28 outputs a pseudo-operation signal with respect to slave units 18, 20 when executing an inspection mode. Accordingly, calling signals are generated in the slave units 18, 20 and the generation state is held. The calling signals are inspected by the monitoring device 28. Thereafter, pseudo-response signals are output to the slave units 18, 20 by the monitoring device 28. Thus, the holding of the generation state is released in the slave units 18, 20. The loss of calling signals are inspected by the monitoring device 28.SELECTED DRAWING: Figure 9

    【課題】エレベーター用インターホンにおいて、子機内の呼出信号生成回路の点検を自動化する。【解決手段】監視装置(点検装置)28は、点検モードの実行時に、子機18,20に対して疑似操作信号を出力する。これにより、子機18,20において呼出信号が生成され、その生成状態が保持される。監視装置28は呼出信号を検査する。その後、監視装置28は子機18,20に対して疑似応答信号を出力する。これにより、子機18,20において生成状態の保持が解除される。監視装置28は呼出信号の消失を検査する。【選択図】図9
