When the location information input through the input unit 110 is the first floor, it is possible to set the fire broadcasting zone information corresponding to the first floor to the first, second, third, fourth, and fifth floors through the user input unit 140. In this way, the user can arbitrarily select the fire broadcasting zone information. This is because the public address system and the fire receiving panel are changed, and when it is necessary to change the broadcasting area to which the fire emergency broadcasting corresponding to each fire generating area is transmitted, it is easy to change the position information of the broadcasting area through the user input unit 140. It is possible. As a result, when a change is required, it is possible to eliminate the difficulty of performing physical wiring again as before.

The user input unit 140 may further include a selection key (not shown) for selecting one of the input channels 112 of the input unit 110. When the selection key is applied, a control signal corresponding to the selection key is output to the controller 150.

The display unit 145 is to display the fire broadcasting zone information corresponding to each input channel 112 to the outside, and a plurality of LEDs to correspond to each input channel 112 on the front panel of the fire detection receiving apparatus 100. Can be prepared as.

When the fire generation zone information is input from the input unit 110, the controller 150 extracts the fire broadcasting zone information corresponding to the input fire generation zone from the storage unit 120, and outputs the extracted fire broadcasting zone information. Output to the PA system through the unit 130. The controller 150 automatically performs such a series of operations when fire occurrence zone information is input from the input unit 110. This operation is performed by the controller 150 performing a pre-programmed macro. The controller 150 stores the fire broadcasting zone information corresponding to each fire occurrence zone in the storage 120 according to a signal input through the user input unit 140.

As such, when the fire detection zone information is input, the fire detection zone apparatus 100 according to the present embodiment automatically controls the fire broadcasting zone information of the fire emergency broadcast by performing a pre-programmed macro. By outputting to the PA system, it is possible to implement a fire emergency broadcast of the direct ignition system without using the conventional physical wiring. In addition, it is possible to arbitrarily select the broadcast zone of the emergency broadcast corresponding to the fire occurrence zone through the user input unit 140, it is possible to easily cope with changes in the fire receiving panel or PA system.
