Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides information obtained from various locations on each floor of a building, such as gas leaks and theft! If information on whether or not II is occurring is displayed from the terminal device 1q installed in each of the above locations to a medium fire monitoring device installed in a control room, etc., using a television public listening system, for example, The present invention relates to an alarm system that is displayed on a floor monitoring device so that prompt action can be taken.

Conventionally, in this type of alarm device, each terminal device is sequentially called by a discharge signal sent from a medium fire monitoring device, and the information input from each called terminal device is sent once as a response signal to the central device. After sending it to the monitoring device and displaying the presence or absence and type of abnormality, if there is an abnormality, the central monitoring device sends a message to each floor monitoring device G. A corresponding return signal is sent out, and this return signal is used to display the floor monitoring device for the floor where the abnormality is occurring (some devices display this abnormality).

These discharge signals, response signals, and return signals are sent at different frequencies to prevent the central monitoring device, terminal devices, and floor monitoring devices from malfunctioning, but for this reason, the discharge signal is not sent to the central monitoring device. This method requires a separate modulation circuit, a modulation circuit for transmitting a return signal, and a reception circuit for receiving a response signal, which has the disadvantage of complicating the circuit configuration.

Additionally, a communication device is usually installed between the floor monitoring equipment and the central monitoring equipment in order to discuss how to deal with abnormal conditions, but under abnormal conditions, confusion occurs on the floor equipment side. I sometimes forget to tell them if something is wrong. For this reason, it is desirable to be able to display on the central monitoring device which communication device the user is talking to, but in order to do this, the floor monitoring device must be equipped with a modulation circuit that sends out a signal that includes the floor address, and the central monitoring device must be able to display this signal. This requires a demodulation circuit that demodulates the data and a display circuit that displays according to the floor address.

The present invention aims to simplify the configuration of a central monitoring device and to provide a kill alarm device that displays which floor monitoring device's communication device is being used without adding a large number of circuits.

Next, when this leakage information is displayed, it is assumed that the communication device 86 attached to the floor monitoring device unit 8-2 is used.

When the communication device 86 is used, a high level output is sent to one input terminal of the AND circuit 84 via the switch 88. Since the other input terminal of the AND circuit 84 is connected to the floor address matching circuit 76, the output of the AND circuit 84 is connected to the terminal device 4-2 on the same floor as the floor monitoring device unit 8-2.
