The repeater T _a2 controls the operation / stop of the smoke preventive equipment U connected to the repeater T _a2 itself via the signal line L ₃ based on the instruction of the self-fire alarm receiver A, and the smoke preventive smoke. The state of operation / stop / failure of the equipment U is monitored based on the instruction of the self-fire alarm receiver A, and the information on the operation / stop / failure of the smoke emission control equipment U is transmitted to the self-fire alarm receiver A. .. The fire detector S _a uses the information (fire detection information) of the fire detector S _a itself based on the instruction of the self-fire alarm receiver A.
_a is transmitted directly to the fire alarm receiver A.

The self-fired alarm receiver A receives a plurality of relays T _a1 and a plurality of relays T _{a2 and a} plurality of fire detectors S _a received by a transmission section (not shown) of the self-fired alarm receiver A. Based on the information from, the display unit (not shown) displays the location of the fire and the operation / stop / failure status of the smoke proof device U. Also,

As described above, the receiver centralized processing type self-warning alarm receiver A is a plurality of receiver centralized processing type transmitted via the transmission line L _a with _a transmission signal composed of high and low voltage levels. The relays T _a1 , T _a2 and the receiver centralized processing type fire detectors S _a are equipped with a transmission unit (not shown) for exchanging data with each other, and the self-fired alarm receiver A concentrates information. Are to be processed in a physical manner.

The relay distributed processing type disaster prevention system shown in FIG. 4 includes a self-fired alarm receiver B having a relay distributed processing type transmission section (not shown) and a plurality of relay distributed processing type repeaters T. _b
It consists of and. Then, dicaprate paper receiver B is connected to a plurality of repeaters T _b repeater distributed processing type via the transmission line L _b.

The self-fired alarm receiver B and the plurality of repeaters T _b are
Data is exchanged with each other via a transmission line L _b by a transmission signal (also called a current loop transmission signal) having high and low current levels.

The repeater T _b has a signal line L connected to the repeater T _b itself.
_The relay T _b itself independently monitors the plurality of fire detectors S connected via ₂ and the terminating resistance R connected to the end of the signal line L ₂ , and the information of the fire detector S (fire detection information) And disconnection information of the signal line L ₂ is transmitted to the self-fired alarm receiver B in response to a request from the self-fired alarm receiver B.

As described above, the repeater distributed processing type self-fired alarm receiver B uses a plurality of transmission signals (current loop transmission signals) consisting of high and low current levels via the transmission line L _b. And a transmission section (not shown) for exchanging data with the repeater T _b of the distributed processing type, and the fire alarm receiver B requests and processes the received information as needed. At the same time, it is possible to perform individual control and send a repeater interlocking table.

By the way, in the disaster prevention system, according to the Fire Service Act, the sound device (area bell) must be activated within 5 seconds after the fire detector S _a or the fire detector S detects _a fire. There are restrictions.

Therefore, in the centralized receiver type disaster prevention system, when the number of installed fire detectors S _a, S and smoke control equipment U increases, the transmitter section of the centralized receiver type fire alarm receiver A ( (Not shown) exchanges data with the fire detector S _a and the relays T _a1 and T _a2 via the transmission line L _a , which causes a problem in processing speed and satisfies the restrictions of the Fire Defense Law. Disappear. Therefore, a transmission unit is added to the fire alarm receiver A and the transmission line L
_A situation arises in which _a is increased and the fire detectors S _a, S and the smoke control device U must be appropriately distributed and connected. In addition, the transmission unit (not shown) of the self-fired alarm receiver A itself has _a restriction on the number of connected fire detectors S _a, S and relays T _a1 , T _a2 due to the load capacity. A situation arises in which it is necessary to increase the number of transmission lines L _a and increase the number of transmission lines La in the receiver A, and to appropriately distribute and connect the fire detectors S _a, S and the smoke control equipment U.

However, in the repeater distributed processing type disaster prevention system, the ringing of the audio device (district bell) can be interlocked and controlled by the repeater distributed processing type repeater T _b , and many fires can occur in one repeater T _b. Unless the detector S is connected, it is irrelevant to the restriction on the Fire Service Act that the sound device (district bell) must ring within 5 seconds after the fire detector S detects a fire. In addition, even though the transmission unit (not shown) of the self-fired alarm receiver B itself has a restriction on the load capacity, even if the number of connected fire detectors S is large, the repeater T _b does not have the repeater T _b itself. since monitors a fire detector S that connects to the repeater T _b itself through a stand-alone device to the signal line L _2, the load of the repeater T _b to say that because now many fire detector S is Only by increasing, the load of the transmission part of the self-fired alarm receiver B does not increase unless the number of repeaters T _b increases.

Moreover, the number of fire detectors S that can be connected to one repeater T _b is quite large, and one of the fire alarm receivers B can be used.
The number of fire detectors S that can be connected to one transmitter (not shown) is much larger than the number of fire detectors S that can be connected to one transmitter (not shown) of the self-fire alarm receiver A. There are many crabs.

By the way, the receiver central processing type repeater T _a
Is inexpensive because the repeater T _a itself does not have a function of performing judgment processing. On the other hand, the repeater distributed processing type repeater T
_b is expensive because it has a function for the repeater T _b to perform judgment processing.

Therefore, the receiver centralized processing type disaster prevention system lowers the functions of the repeaters T _a1 and T _a2 by making the function of the self-fire alarm receiver A highly functional and makes it inexpensive. Except when adding the transmission part (not shown) of the self-fired alarm receiver A, that is, unless the transmission part (not shown) of the self-fired alarm receiver A is added, the cost for the function of the entire disaster prevention system is optimal. Is to be. In other words, the receiver centralized processing type disaster prevention system is suitable for small-scale (with a small number of management points). The number of control points refers to the number of fire detectors and smoke control equipment installed, and increases substantially in proportion to the floor area of the building.

On the other hand, in the distributed relay type disaster prevention system, the function of the repeater T _b is made highly functional so that the function of the fire alarm receiver B is not made highly functional, and the function of the entire disaster prevention system is improved. The cost is optimized. In other words, the repeater distributed processing type disaster prevention system is suitable for large scale (many management points).

[0021]

However, from a user's point of view, a small-scale disaster prevention system with a small number of management points requires a receiver centralized processing type disaster prevention system that optimizes the cost for functions, and a large-scale disaster management system with a large number of management points. Middle-scale disaster prevention system with a moderate number of control points, which has the best cost for functions Disaster prevention system is required. However, there was a problem that it could not cope with this.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a medium-scale self-ignition bulletin in which the cost for the function is optimal in the case of a medium-scale disaster prevention system. To provide a receiver.

[0023]

In order to solve the above problems, the present invention is provided with a display unit for displaying a fire, an operation unit for controlling, and a transmission unit for performing data communication with a repeater. The fire alarm receiver is provided with a first transmission section for performing data communication with the first type repeater and a second transmission section for performing data communication with the second type repeater. To do.

[0024]

With the above construction, two types of repeaters can be used for one self-fired alarm receiver.
