Abstract

PURPOSE:To attain the inexpensive alarm equipment with detailed display using a digital private branch exchange by connecting a smoke, heat and fire alarm sensor to a telephone set of each guest room and sending automatically a signal through the operation of the sensor. CONSTITUTION:If a fire breaks out at a guest room of a hotel, a smoke sensor 1 in a telephone set 2 placed aside a bed is operated by smoke. An output is produced to a smoke signal conversion section 12, an on-hook sending signal is sent to a pulse dialer 21 by the operation of the 1st transducer of an automatic sending control section 13 and the talking enable state is formed even if a handset 25 hooks on. A pulse corresponding to a specific number call is sent to the pulse dialer 21 by the operation of the 2nd transducer, and the 3rd transducer is operated, a bell rings via a bell ring circuit 23 and fire breakout is informed to a person in the room. Further, a dial impulse is sent to a private branch exchange via the pulse dialer 21 and a speech network 24, a special number is detected and the breakout of fire and its room are displayed on a display device provided to the front desk.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a fire alarm system for hotels and the like equipped with a digital private branch exchange.

<Prior art> Conventionally, in buildings with many guest rooms such as hotels, in order to subdivide and display the area where the fire occurred, fire detectors are provided with addresses, and the fire signal and its address are reported to the receiver. I tried to notify them promptly.

<Problems with the prior art> However, in the above-mentioned device, it is necessary to provide an address circuit in the sensor, and also provide a circuit in the receiver to decode the address and a device to display the room where the fire occurred. However, the disadvantage was that the equipment was expensive.

(Means for Solving the Problems) In view of the above points, the present invention is based on the above points, and when a digital private branch exchange installed in a hotel etc. calls a specific number from a guest room, the guest room number is displayed on the front indicator and the number of the guest room is displayed. Focusing on the fact that cleaning is being reported, a fire alarm device that detects smoke or heat is connected to the telephone in each room, and the pulse dialer of the telephone is connected to the telephone in each room. The system is equipped with an automatic call control unit that generates an on-hook call signal and a signal for making a special number call, and displays the occurrence of a fire and the room in which it occurred on a display installed at the front desk etc. via a digital private branch exchange. .

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

Figures 1 and 2 show different embodiments of telephones installed in hotel rooms, etc. Figure 1 shows a fire detector and a phone 2 in which smoke detector 1 is built-in, and Figure 2 are installed separately; 3 is the power supply for the smoke detector l; 4 is the power supply for the smoke detector l;
is the electric wire of telephone 2.

FIG. 3 shows the configuration of these circuits. The smoke detector 1 includes a sensor section 11 of an ion type or a photoelectric type, and a smoke signal conversion section 12 consisting of a comparator or the like that detects a predetermined output from the sensor section 11. , an automatic transmission control section 13 operated by the output of this conversion section 12, and a power supply section 14 for these
It consists of

The automatic call control unit 13 sends a pulse corresponding to a special number between a first pulse transmitter that sends an off-hook call signal to the on-hook terminal of the pulse dialer 21 of the telephone 812 and an electric line connecting the pulse dialer 21 and the keyboard 22. It is composed of a second pulse transmitter and a third pulse transmitter that operates the bell ringing circuit 23. Further, 24 is a speech network, and 25 is a handset.The operation of the above-mentioned device will be explained below.

When a fire breaks out in a hotel room, a smoke detector 1 in a telephone 2 placed next to the bed is activated by the smoke. Then, an output is generated in the smoke signal converting section 12, and an on-footer transmission signal is sent to the pulse dialer 21 by the operation of the first transmitter of the automatic transmission control section 13, so that even if the handset 25 is placed, it is possible to make a call. be done. Then, by the operation of the second transmitter, a pulse corresponding to the special number call is sent to the pulse dialer 21.
The third transmitter is activated and the bell ringing circuit 23 is activated.
A bell rings to notify people in the room that there is a fire.

Also, the pulse dialer 21 and the speech network 2
4, the dial impulse is sent to a private branch exchange, not shown. The private branch exchange detects the special number sent, and a display installed at the front desk displays the fact that a fire has occurred and the room in question.

Effects> Since the fire alarm system of the present invention is configured and operates as described above, it has the effect of providing a fire alarm system for hotels and the like that uses a digital private branch exchange and is capable of displaying subdivisions at low cost.
