[Problem to be Solved by the Invention] However, since the conventional emergency notification device has the above-mentioned configuration, when checking its function during maintenance work, the alarm buzzer continues to sound until the reset means is activated. This alarm sound can be harsh and bothersome to residents near where the elevator is installed.

In addition, when maintenance personnel dispatched at night, etc., contact the service center, they usually use the telephone, but if there are no public telephones nearby, they may use the elevator's emergency call device. However, as mentioned above, if the emergency call device is used, the alarm buzzer will sound at a loud volume, which may disturb nearby residents' sleep.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator emergency notification device that can be used during maintenance work, etc. without causing inconvenience to nearby residents.

[Means to solve the problem]

In order to achieve the above object, the present invention enables mutual communication between a first communication device provided in an elevator car and a second communication device provided in a service center using a telephone line. In the elevator emergency notification device, the first communication device is connected to a car, and is configured to sound an alarm buzzer installed in the car at least until a reset means is activated when the first communication device is activated. Operation number.

A means for suppressing the ringing sound of the alarm buzzer, and a specific switch for operating the suppressing means are provided on the operation panel.

[Effect]

Since the elevator emergency notification device according to the present invention is configured as described above, a means for suppressing the sound of the alarm buzzer works by operating a specific switch, so that the function test and maintenance that occur during maintenance work can be completed. There is no need to disturb nearby residents by informing them that the event has occurred.

First, it is assumed that a failure occurs in the U4L novator, the elevator car stops at an intermediate position between floors, a passenger is trapped in the car, and the call button is operated by passenger No. 1 J. Then, this operation closes the call button contact point 0.11, and the call activation relay 12 and the alarm activation relay 1 are closed.
The alarm starting relay 13 is self-held by the contact 13a which is the normally closed contact of the alarm starting relay la. At this time, the alarm sound suppression switch 14 is turned on and the alarm sound is not turned on.
- Alarm sound suppression switch detection relay...-15 is not energized, so its normally closed contact 15a is open and not 1. For this reason, while the alarm starting relay 13 is self-held, the alarm buzzer 50 and the calling buzzer 51 are connected between the power supplies P and N through the contact 13a2 and continue to sound.

Residents and managers in the vicinity who noticed the sound of the alarm buzzer 50 and the call buzzer 51 contacted a maintenance company, etc., and when the reset button 19 was operated, the alarm activation relay] Since the self-holding circuit No. 3 is opened, the alarm starting relay 13 is deenergized, and the contact 13 is accordingly deenergized.
a2 is opened, and the sounding of the alarm buzzer 50 and the calling buzzer 51 is stopped.

At this time, contact 12 is activated by energizing call starting relay 12.
Since the communication circuit N2 is activated when the communication circuit N2 is closed, the communication circuit 16 sends out a signal to call the communication device N2, and this sent signal causes the contact 6a to be closed and the display device 2; 3 is activated, and the telephone call device for the service center staff is activated.

Also, based on the signal sent from the communication circuit 16, the contact 1
6a2 is closed and the communication circuit 20 is activated, and when a response device (not shown) of this communication circuit, such as a transmitter/receiver such as a telephone or a communication state setting switch, is operated, the communication circuit 20 is set to the communication state i1. Along with contact point 2
An establishment signal is sent to close telephone line 1 and thereby to close telephone line 3. When this communication circuit 20 becomes ready for communication,
This establishment signal is transmitted via the telephone line 3 to the communication circuit 1-6, and the communication circuit 6 that receives this signal sends the establishment signal 7 button which puts the communication circuit 6 into a ready state for communication. Set it to a state where you can make calls.

In this way, the communication circuit 16 and the communication circuit 20 are connected, and the passengers trapped in the elevator can easily understand the situation.
The passenger will contact the staff at the bus center, who can then contact the passenger to take action.

When mutual communication has been confirmed, when the above-mentioned handset and operation switch (not shown) provided in the communication circuit 20 is operated, the contact point 22 opens and a stop signal is sent from the communication circuit 20, and the communication circuit 20 When you stop the operation of
Control is also performed to open the telephone line 3. This signal is transmitted to the communication circuit 6 via the telephone line 3, and based on this signal, the contact unit 8 opens and a stop signal to stop the operation is sent from the communication circuit 16, and the communication circuit 6 stops its operation.

Next, the operation of the emergency notification device during maintenance work will be explained.

First, during periodic maintenance inspection, communication equipment W] and communication equipment W2
When performing a function confirmation test with the alarm sound suppression switch 1
Operate 4. Then, the alarm control/suppressing switch detection relay 5 is connected between the power supplies P and N and energized, and its normally closed contact 15b is opened. Therefore, when the maintenance personnel performs the same operation to disable the communication device F, 1 & 13 as mentioned above, the communication circuit] 6 and the alarm activation relay [] 3 are activated, but the alarm buzzer 50 is activated. Since the ringing buzzer 51 and the limiting resistor 52 are connected in series between the power supplies P and N, the volume of the ringing is suppressed.Therefore, the notification operation confirmation and alarm between the call circuit 16 and the call circuit 20 are performed. Confirmation can be performed by the suppressed volume of the buzzer 50 and the calling buzzer 51, and noise problems for residents near the elevator can be solved.

In addition, when a maintenance worker dispatched to a night watch for a breakdown call informs the service center that the troubleshooting has been completed, he can activate the communication device as described above and use the communication means for contacting the service center. can be used as,
There is no need to go to a place where there is a public telephone, and the efficiency of maintenance work can be greatly improved.
