The present invention relates to an emergency call device for a fire alarm system and an emergency call method using the same.

In general, fire alarm systems are installed in buildings to reduce the risk of human injury in the event of a fire. These fire alarm systems automatically detect a fire through a detector that detects heat, smoke, flames, etc. generated by a fire, or an operating device such as a bell, siren or indicator light when a predetermined transmitter is operated by the fire detector. It is a system that generates an alarm to a person or a resident within a building.

In order to perform this function, the fire alarm system detects a fire and generates a detection signal, a transmitter that generates an operation signal as operated by a fire detector, and a location where a fire occurs by receiving the detection signal or an operation signal. It consists of a fire receiver for generating an alarm through the operating device and an operating device for generating an alarm, wherein the fire receiver is largely P-type fire receiver and R-type fire receiver, each of which adds a gas leakage detection function.

This is obvious to the person (hereinafter referred to as "the person in charge").

Hereinafter, with reference to Figure 6, the emergency call method for a fire alarm system according to a preferred embodiment of the present invention will be described in detail based on the operation and use of the emergency call device for the fire alarm system.

First, when the caller of the repeater 30 or the like operates the call request unit 1000 provided in the repeater 30 to initiate an emergency call, a call request signal is generated, and the central processor 800 of the repeater 30 is operated. The call transmits the call request signal to the central processing unit 300 of the fire receiver 10 through the communication line 20 (s100).

Next, when the central processing unit 300 receives the call request signal from the central processing unit 800, the request sound signal data is transmitted to the first sound unit 200, and the first sound unit 200 requests the request sound signal data. Output as a beep (s200).

Thereafter, the central processing unit 300 checks whether a call acceptance signal is received (S300). At this time, if the manager of the fire receiver 10 operates the call acceptor 500 provided in the fire receiver 10 to express the intention to accept the call, the call accept signal generated by the call acceptor 500 is sent to the central processing unit 300. The central processing unit 300 transmits the call sound data of the second microphone 600 received from the central processing unit 800 to the first sound unit 200 to output the sound.

That is, when the caller of the repeater 30 or the like inputs the call tone to the second microphone 600, the second microphone 600 generates the call tone as the call tone data (S400), and the call tone data is the central processor ( 800). At this time, the call tone data of the second microphone 600 in the form of an analog signal is converted into a digital signal form by the second codec unit 900, and the converted call tone data is processed by the central processor 800 by the central processor 800. (S500).

Thereafter, the central processing unit 300 transmits the call sound data of the second microphone 600 received from the central processing unit 800 to the first sound unit 200 after the call acceptance signal is transmitted. The sound unit 200 outputs this as a call sound (s600).

When the call sound data of the second microphone 600 is transferred from the central processing unit 300 to the first sound unit 200, the call sound data of the digital signal form is converted into an analog signal form by the first codec unit 400. The conversion and amplification of the intensity by the amplifier 210 can be done.

Then, similarly, a series of processes are performed in which a call sound input to the first microphone 100 by the manager of the fire receiver 10 is output to the second sound unit 700 of the repeater 30. This is because the emergency call apparatus for the fire alarm system and the emergency call method using the same according to the preferred embodiment of the present invention implement an emergency call in both directions. Of course, only one-way emergency call may be implemented.

Specifically, when the manager of the fire receiver 10 inputs the call tone in the first microphone 100, the first microphone 100 generates the call tone as call tone data (s700), and the call tone data It is transmitted to the central processing unit 300. At this time, the call tone data of the first microphone unit 100 in the form of an analog signal is converted into a digital signal form by the first codec unit 400, and the converted call tone data is processed by the central processing unit 300 by the central processor 800. (S800).

Thereafter, the CPU 800 transmits the call sound data of the first microphone 100 received from the CPU 300 to the second sound unit 700, and the second sound unit 700 transmits the call sound data. The call outputs the sound (s900).

Of course, similar to the above, when the call tone data of the first microphone unit 100 is transferred from the central processor 800 to the second sound unit 700, the second codec unit 900 in the form of a digital signal The operation of converting the call sound data into an analog signal form and amplifying its strength by the amplifier 710 may be performed.

As described above, according to the emergency call apparatus for the fire alarm system and the emergency call method using the same, the first microphone 100 and the first sound unit 200, a plurality of, provided in the fire receiver 10 Through the plurality of second microphone unit 600 and the plurality of second sound unit 700, respectively provided in the repeater 30 of the fire receiver to the call sound data generated in the first second microphone unit (100, 600) By transmitting and receiving through the common communication line 20 connecting the 10 and the plurality of repeaters 30 to the call sound through the first second sound unit 200, 700, respectively, to install a separate emergency telephone facility Without having to implement an emergency call between the fire receiver 10 and the plurality of repeaters 30, the installation cost can be greatly reduced, and the construction and maintenance is very easy.
