Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a fire alarm device such as a hotel equipped with a digital private branch exchange.

<Prior art> Conventionally, in a building with a large number of guest rooms such as hotels, in order to subdivide and display the fire occurrence area, an address is provided to the fire detector, the fire signal and its address are reported to the receiver, and the fire occurrence area is reported. Was to be notified promptly.

<Problems of the prior art> However, in the above-described device, it is necessary to provide an address circuit in the sensor, and also in the receiver, a circuit for decoding the address and a device for displaying the room in which the fire has occurred. However, there was a drawback that the equipment was expensive.

<Means for Solving Problems> In view of the above points, the present invention has been made so that when a digital private branch exchange provided in a hotel or the like calls a specific number from the guest room, the guest room number is displayed on the front indicator. Focusing on the fact that cleaning has been completed, a fire detector that detects smoke or heat is connected to the telephone in each room, and this output automatically sends the telephone in the same room The output is connected to the automatic dial controller, and this output is connected to the pulse dialer and bell ringing circuit in the telephone,
When a fire occurs, a special number call is made, and the fire occurrence and its room are displayed on the display such as the front via the digital private branch exchange.

<Operation> When a fire occurs in the room, the fire alarm device configured as described above activates the fire detector connected to the telephone and rings the bell of the telephone to notify the customer, such as sleeping, that the fire has occurred. At the same time, a special number call is made to display the fire and its room on the display such as the front via the digital private branch exchange.

<Embodiment> An embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 show different embodiments of a telephone set in a guest room of a hotel, etc., FIG. 1 shows a smoke detector 1 as a fire detector built in a telephone 2, and FIG. It is provided on the body, 3 is the power supply of the smoke detector 1, 4
Is an electric wire of the telephone 2.

FIG. 3 shows these circuit configurations. The smoke detector 1 is a smoke signal conversion unit 12 including an ion type or photoelectric type sensor unit 11 and a comparator for detecting a predetermined output from the sensor unit 11. And an automatic transmission control unit 13 operated by the output of the conversion unit 12, and a power supply unit 14 for these.

The automatic transmission control unit 13 uses the pulse dialer 21 of the telephone 2.
A first pulse transmitter that sends an off-hook transmission signal to the off-hook terminal of the, a second pulse transmitter that transmits a pulse corresponding to a special number between the electric path connecting the pulse dialer 21 and the keyboard 22, and a bell ringing circuit in the telephone. Third to operate 23
It consists of a pulse generator. Further, 24 is a speech net work and 25 is a handset.

Next, the operation of the above device will be described.

When a fire occurs in a hotel guest room, the smoke detector 1 in the telephone 2 placed near the bed is operated by the smoke. Then, an output is generated in the smoke signal conversion unit 12 and the first signal of the automatic transmission control unit 13 is generated.
The off-hook transmission signal is sent to the pulse dialer 21 by the operation of the transmitter of (1), and a call is made possible even if the handset 25 is placed. And the pulse corresponding to the special call is sent to the pulse dialer 21 by the operation of the second oscillator,
In addition, the third oscillator operates and the bell rings through the bell ringing circuit 23 to notify the sleeping passenger in the room that a fire has occurred.

Also, the dial impulse is sent to a private branch exchange (not shown) through the pulse dialer 21 and the speech network 24. The private branch exchange detects the special number sent to you,
The display of the fire and the room are displayed on the front display. As a result, a staff member rushes to the fire room to extinguish the fire, or depending on the extension of the fire, ring the bells of the telephones in other rooms all at once to notify that the fire has started.

<Effect> Since the fire alarm device of the present invention is configured and operates as described above, even if a fire occurs in a room, the customer of the room is notified by the telephone bell and is displayed on the front through the private branch exchange. Therefore, even if there is a fire in a room, only the room will be notified at the initial stage and it will not be notified to the guests in other rooms.
There is an effect that a fire alarm device for a hotel or the like can be obtained at low cost using a digital private branch exchange that can quickly perform fire fighting or blame guidance without disturbing many people.
