Activate the dialing device, connect the handset to the operator answering device installed in the monitoring center via the telephone circuit, set the communication between them to be possible, and record the voice of the call to the recording device. In the elevator communication device for recording, an inspection signal generating device is provided in the terminal device, is operated by an inspector during inspection work, and adds an inspection signal to information transmitted to the monitoring center, and an inspection signal generating device is provided in the monitoring center. , a recording cutoff device that cuts off the connection between the operator response device and the recording device when the inspection signal generation device is activated.

In the present invention, when an inspector operates the inspection signal generation device during inspection work, the automatic dialing device detects the operation of the inspection signal generation device in the information transmitted from the terminal device to the monitoring center via the telephone line. An inspection signal is given by

Furthermore, when the inspection signal generation device is activated, the monitoring center disconnects the operator response device and the recording device.

Therefore, the conversation between the inspector and the monitoring center operator during inspection work is not recorded, and the communication device operates efficiently.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a block diagram of the embodiment, and the same parts as in Fig. 2 are given the same reference numerals.◇As shown in the figure, the embodiment is different from the conventional elevator communication device. In the terminal equipment installed in the manager's room [T, an inspection signal generation device 14 is arranged in parallel to the abnormality signal generation device 13, and a switching device 12 connected to the control device 10 detects an abnormality a.
