Description

Technical Field [0001] The present invention relates to an operating system and a method for operating a fire relay repeater,

The present invention relates to an operating system and method for short circuit inspection of a fire alarm relay broadcasting apparatus line, and more particularly, to a fire alarm system for detecting a short circuit state of a speaker and a broadcast speaker connected to a fire alarm relay broadcasting apparatus, The present invention relates to an operating system and a method for operating a fire alarm repeater broadcasting line according to a short circuit inspection of the fire alarm repeater broadcasting line so that normal broadcasting and general broadcasting can be smoothly transmitted.

Generally, fire alarm systems are legally required to install fire alarm systems in public buildings, offices, factories, apartments, subways and other places where people are often gathered. FIG. 1 schematically shows a line wiring state of a fire detector for directly detecting a fire in such a conventional fire alarm system.

Referring to FIG. 1, a plurality of fire detectors 3, 4, 5 for detecting the occurrence of a fire is installed between the relay 1 and the transmitter 2. The plurality of fire detectors (3, 4, 5) constitute a line to be electrically connected to each other between the relay device (1) and the transmitter (2).

When a fire is detected by the plurality of fire detectors (3, 4, 5), a detection signal indicating the occurrence of a fire is provided to the relay device (1) from a fire detector which detects the fire. The repeater 1 notifies the disaster prevention center or the control center of the occurrence of a fire through a fire receiver (not shown).

The number of the fire detectors 3, 4 and 5 may be increased according to the size of the installation place of the fire alarm system. In the fire alarm system, ) Increases in proportion to the number of lines.

Generally, in the fire alarm system, termination resistors 6 and 7 are installed as shown in FIG. 1 to check the line break of the fire detector line formed as described above. The terminating resistor must be located at the end of the line, that is, at the position shown by reference character "B" in Fig.

However, in order to reduce the trouble of maintenance and equipment maintenance due to disconnection of the line, the installer of the fire alarm system needs to install the termination resistor at the end of the line, that is, There are a few cases to install. This is because the line is detected to be in a normal state when viewed from the position of the repeater 1 even if a line break occurs between the installation position A of the termination resistor 6 and the transmitter 2. Accordingly, the fire detectors 4 and 5 installed between the position "A" and the transmitter 2 can not detect the occurrence of fire, and the fire alarm device can not generate a fire alarm.

According to the above-described apparatus, the voltage level of the power supply / signal line before the power supply interruption is compared with the line voltage level after a predetermined time elapses from the power supply interruption, and based on this result, The paragraph is discerned.

However, according to the above-described conventional apparatus, it is not possible to correctly check the disconnection state of the line depending on the installation position of the terminal resistance, and it is impossible to distinguish the disconnection state of the fire detector line from the fire occurrence state. Further, since the indicator lamp attached to the transmitter at the time of occurrence of the fire maintains the lighting state at all times, it is very difficult to grasp the position of the indoor fire hydrant in the case of a fire in which a large amount of smoke is generated.

As a prior art for solving the above problems, Korean Patent Laid-Open Publication No. 2001-0107430 (Dec. 12, 2001) discloses " line disconnection and fire generation monitoring device and monitoring method for a fire alarm system, A plurality of sensing means for sensing occurrence and outputting a fire occurrence signal; A sensor voltage signal indicating a current voltage state of the plurality of sensing means is inputted through a line connecting the plurality of sensing means, the level of the sensor voltage signal is compared with a predetermined reference voltage level, Control means for generating a disconnection control signal or a fire control signal indicating a disconnection or a fire occurrence of a line connecting the plurality of sensing means; First alarm means for informing a user that a line connecting the plurality of sensing means has been disconnected in response to the disconnection control signal; And a second alarm means for informing the user that a fire has occurred in response to the fire control signal.

According to the above-described fire alarm system, the normal voltage level of the plurality of fire detectors is compared with the operation voltage level of a plurality of predetermined fire detectors as the reference voltage level by the control unit, and according to the comparison result, And a detection signal for electrically connecting the plurality of fire detectors and a detection signal indicating a line state of the common line.

When the abnormal current is instantaneously applied in a state that the circuit is not disconnected, it is determined whether or not the line of the sensing line and the common line is disconnected and whether a fire is generated. A control signal is generated and applied to a fire alarm system to erroneously recognize that a fire has occurred.

In addition, the fire-fighting R-type receiver 100 is connected to the fire fighting repeater broadcasting apparatus 200 to temporarily isolate the circuit from the abnormal fire fighting repeater broadcasting apparatus 200, and temporarily excludes the abnormal circuit among the monitored circuits And works normally.

As shown in the figure, the fire fighting repeater broadcasting apparatus 200 includes a fire fighting repeater 210 and a broadcasting apparatus 220. A fire detector and a transmitter (not shown) are connected to the fire alarm relay broadcasting apparatus 200, and a fire alarm, a visual alarm, and an electronic siren are connected to the transmitter (not shown).

The fire-fighting repeater 210 plays a role of converting a contact signal into a communication signal and a communication signal into a contact signal. The signal of the fire-fighting repeater 210 is divided into an input signal and an output signal.
