Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency notification system, and particularly to an emergency notification system that is carried out in inns, hotels, etc. using an exchange system.

In the case of hotels such as inns (in facilities where guests are accommodated in separate guest rooms), in the event of a disaster such as a fire, it is necessary to notify guests of the disaster and guide guests to a safe location. Conventionally, fire alarms are placed in corridors, etc., and when a fire occurs, the fire alarm rings an emergency bell and makes a simultaneous emergency announcement using the in-house public address system to notify the fire. It is customary. However,
With this type of method, the soundproofing of buildings is currently advanced.
In cases where the guests are sound asleep, it is extremely difficult to reliably notify all guests of a fire and evacuate them without fail. Given this current situation, there have been recent reports of hotel fires in which many precious lives were lost, indicating that conventional disaster prevention equipment is inadequate.

The present invention eliminates the above-mentioned drawbacks of the prior art and provides an emergency notification system using a private branch exchange system that makes it possible to reliably notify guests in all guest rooms of the occurrence of a disaster.

In order to achieve this objective, the present invention makes use of telephones installed in each guest room, and in the event of a disaster, a forced emergency call is made to this telephone, and if a guest picks up the telephone, the telephone An emergency report will be transmitted from an emergency report device, etc. to
It is characterized by having Vc.

The present invention will be explained in detail below with reference to the drawings.

The drawing is an example of the present application. PBX is a private branch exchange that is conventionally installed in inns, hotels, etc., ATT is a switchboard, MDF is a centralized terminal board, SUB, etc.

5UB2... is the extension telephone of the exchange, CO is the central office line, A
MP is a broadcasting amplifier, and SP is a broadcasting speaker device. The type of exchange equipment is not particularly limited, such as automatic type, shared electric type, etc. In addition, AS, AS2... are alarm switches that automatically or artificially switch in the event of an emergency, and LC.
, LC2... are line circuits. SIG is 1 for ringing the bell built into the extension telephone.
AC signal generator, LS, etc. of 6 Hz or 20 Hz.

LS2... is a line switch, and ALT is an emergency broadcasting device that notifies an emergency situation, and an emergency notification to be broadcast in case of an emergency is set in advance.

The operation of the present application based on the above configuration will be explained. It is usually used as a private branch exchange telephone device.

However, once an emergency such as a fire occurs, a supervisor confirms this and the alarm switches ASI, AS2...
Alarm switch A all at once when manually operated to switch
S+, AS2... switch, telephone SUB, ,
The 5UB2 side... is disconnected from the exchange PBX and connected to the line circuit on the LC, LC2... side. Furthermore, the AC call signal from the signal device SIG activated in the event of an emergency is transmitted through [line switches L S +, L S 2...→line circuits LC+, LC2...→alarm switch A]
S,, AS2... → MDF terminals] 1-1
It is sent to the extension telephones SUB, 5UB2, etc., and rings the bell of the extension telephone. Each indoor telephone rings so that the guest can hook up and answer the call. When the roof of the phone is completed, the answering phone SU
The line circuit LC corresponding to B operates the line switch LS upon detection of a response, and switches from the signal device SIG side to the emergency broadcast device ALT side. Furthermore, the emergency broadcasting device ALT, which is activated in the event of an emergency, repeatedly broadcasts a message conveying the emergency situation, and can notify the extension telephone connected to ALTIII that an emergency situation has occurred. Pre-recorded voice messages can be used for normally anticipated fires, but it is desirable to be able to make verbal emergency calls and provide guidance in case of unforeseen emergencies.

According to the private branch exchange emergency notification device with the above configuration, the existing exchange equipment can be used, and furthermore, if an alarm switch is installed near the MDF, it can be provided at a very low cost without changing the existing wiring work. In addition, if the telephone bell rings at any time, a normal guest will respond immediately, making use of the inherent characteristic of the telephone, which allows emergency messages to be reliably conveyed, ensuring a secure stay. It can guide customers to evacuate.

Although the emergency broadcasting device ALT and the extension telephone may be connected directly in the explanation of the drawings, each line and A'LT may be connected by transformer coupling, and the design is free.

1. The emergency broadcast system ALT is the amplifier AM of the public address system.
It can also be connected to P and speaker SP.

In this case, guests located in locations other than each telephone can be notified of the emergency situation at the same time.

The emergency notification system using the private branch exchange system of the present invention having the above configuration is very inexpensive because most of the existing equipment can be used, and it is also possible to contact guests reliably to guide them to evacuate in the event of a disaster. be.
