Emergency call repeater 101c relays a call voice signal transmitted and received between master unit 101d and handset 101e.

[0052] (1-2-5d) Parent unit The master unit 101d is installed in a predetermined location of the facility (for example, a disaster prevention center or a control room where the receiver 1 is installed) and is operated by a manager or a security guard of the facility. The master unit 101 in this embodiment is provided outside the housing of the receiver 1. The master unit 101d is connected to the fourth communication unit 14 via the fourth communication line L13, and receives an incoming call from the handset 101e via the emergency call repeater 101c and the fourth communication unit 14.

[0053] (1-2-5e) Child unit The handset 101e is installed in a facility and is operated by a user of the facility when an abnormality such as a fire occurs. In detail, when a user finds an abnormality in the facility, the user operates the handset 101e to notify a manager, security guard, or the like at a disaster prevention center of the occurrence of the abnormality. The handset 101e is connected to the emergency telephone repeater 101c via the fourth communication line L13, and makes a call to the master unit 101d in response to the user's operation.

[0054] (1-2-5f) Speaker The speaker 101f is installed in the facility. The speaker 101f is connected to the third communication unit 13 via the third communication line L12, and outputs a broadcast sound corresponding to a broadcast sound signal transmitted by the third communication unit 13.

[0055] (1-2-5g) Microphone The microphone 101g is installed together with the master unit 101d in a predetermined location of the facility (for example, a disaster prevention center or a management room). In this embodiment, the microphone 101g is attached to the outside of the housing of the master unit 101d together with the master unit 101d. The microphone 101g is connected to the third communication unit 13 via the third communication line L12, converts the emergency broadcast voice spoken by the manager into a broadcast audio signal, and inputs the converted broadcast audio signal to the third communication unit 13.

[0056] (1-3) Processing device The processing device 2 is a device for distributing processing between the receiver 1 and has a configuration obtained by removing the emergency broadcast sound source 15 and the fourth communication unit 14 from the receiver 1 (see FIG. 2). That is, the processing device 2 includes a first communication unit 11, a second communication unit 12, a third communication unit 13, a broadcast voice conversion unit 16, and a call voice conversion unit 17, as shown in FIG.

[0057] The processing device 2 has a processor, a memory, and three types of communication modules corresponding to the first communication unit 11 to the third communication unit 13. In the processing device 2, the processor operates based on the programs and information stored in the memory, and further cooperates with the three types of communication modules to realize the functions of the processing device 2 (for example, the first communication unit 11 to the third communication unit 13, the broadcast voice conversion unit 16, and the call voice conversion unit 17). However, the broadcast voice conversion unit 16 and the call voice conversion unit 17 may be realized by dedicated hardware.

[0058] (1-4) Specific example of the first embodiment (1-4-1) Example of communication between a receiver and devices connected to the receiver 2, when a fire occurs in a facility in which the detector 101a is installed, the detector 101a transmits a fire signal to the receiver 1 via the first communication line L11. In the receiver 1, the first communication unit 11 receives the fire signal, and the emergency broadcast sound source 15 outputs a digital broadcast audio signal related to the occurrence of the fire. The broadcast audio conversion unit 16 converts the output digital broadcast audio signal into an analog broadcast audio signal, and the third communication unit 13 transmits the analog broadcast audio signal to the speaker 101f. As a result, the emergency broadcast audio is output from the speaker 101f.

[0059] By listening to the emergency broadcast audio, users of the facility can learn of the occurrence of a fire in the facility and information about the fire that has occurred. Furthermore, when a user discovers a fire in the facility, the user performs an outgoing call operation on the handset 101e of the telephone system to contact an administrator at a disaster prevention center or the like. In response to the outgoing call operation, an outgoing signal is transmitted from the handset 101e to the emergency telephone repeater 101c via the fourth communication line L13. The emergency telephone repeater 101c receives the outgoing signal and transmits the received outgoing signal to the first communication unit 11 via the first communication line L11. When the first communication unit 11 receives the outgoing signal, a ringtone is output from the master unit 101d.

[0060] When the manager performs an incoming call operation on the base unit 101d in response to the ringtone, a call can be made between the base unit 101d and the handset 101e. The analog call voice signal transmitted from the base unit 101d in response to the manager's speech is received by the fourth communication unit 14, and the received analog call voice signal is transmitted from the fourth communication unit 14 to the emergency telephone repeater 101c. The analog call voice signal transmitted from the fourth communication unit 14 is received by the emergency telephone repeater 101c, and the received analog call voice signal is transmitted from the emergency telephone repeater 101c to the handset 101e. The analog call voice signal transmitted from the emergency telephone repeater 101c is received by the handset 101e, and the handset 101e outputs a call voice based on the manager's speech.

[0061] The analog call voice signal transmitted from the handset 101e in response to the user's speech is received by the emergency telephone repeater 101c, and the received analog call voice signal is transmitted from the emergency telephone repeater 101c to the fourth communication unit 14. The analog call voice signal transmitted from the emergency telephone repeater 101c is received by the fourth communication unit 14, and the received analog call voice signal is transmitted from the fourth communication unit 14 to the base unit 101d. The analog call voice signal transmitted from the fourth communication unit 14 is received by the base unit 101d, and the base unit 101d outputs a call voice based on the user's speech. This allows users in the facility to talk to a manager in a disaster prevention center or a management room.

[0062] In this way, when an abnormality such as a fire occurs within a facility, users within the facility can use the emergency telephone system to notify an administrator at a disaster prevention center or the like of the occurrence of the abnormality.

[0063] (1-4-2) Example of communication between the receiver and the devices connected to the processing device 3, when a fire occurs in a facility in which the detector 101a is installed, a fire signal outputted by the detector 101a is transmitted to the second communication unit 12 via the first communication line L11 and the first communication unit 11. Then, a digital fire signal is transmitted from the second communication unit 12 to the receiver 1 via the second communication line L0.

[0064] In the receiver 1 of Fig. 2, the second communication unit 12 receives a digital fire signal, and the emergency broadcast sound source 15 outputs a digital broadcast audio signal. The broadcast audio conversion unit 16 transmits the output digital broadcast audio signal from the second communication unit 12 to the processing device 2 via the second communication line L0.

[0065] 3, the second communication unit 12 receives a digital broadcast audio signal, the broadcast audio conversion unit 16 converts the received digital broadcast audio signal into an analog broadcast audio signal, and the third communication unit 13 transmits the analog broadcast audio signal to the speaker 101f via the third communication line L12. As a result, an emergency broadcast audio is output from the speaker 101f.

[0066] When a user of the facility discovers a fire in the facility, the user uses the emergency telephone system to notify the facility manager of the occurrence of the fire. More specifically, the user who discovers the fire performs a call operation on the handset 101e of the emergency telephone system. In response to the call operation, a call signal is transmitted from the handset 101e to the emergency telephone repeater 101c via the fourth communication line L13. The emergency telephone repeater 101c receives the call signal and transmits the received call signal to the first communication unit 11 via the first communication line L11. When the first communication unit 11 receives the call signal, a digital call control signal indicating a call from the handset 101e is transmitted from the second communication unit 12 to the receiver 1 via the second communication line L0.

[0067] In the receiver 1 of Figure 2, when the second communication unit 12 receives a digital call control signal, an outgoing signal is transmitted from the first communication unit 11 to the base unit 101d via the emergency telephone repeater 101c and the fourth communication unit 14, and a ringtone is output from the base unit 101d.

[0068] When the administrator performs an incoming call operation on the parent unit 101d in response to the ringtone, a call can be made between the parent unit 101d and the child unit 101e. An analog call voice signal transmitted from the parent unit 101d in response to the administrator's speech is converted into a digital call voice signal by the call voice conversion unit 17, and the converted digital call voice signal is transmitted from the second communication unit 12 to the processing device (distributed processing board) 2 via the second communication line L0.

[0069] 3, the second communication unit 12 receives the digital voice signal, and the voice conversion unit 17 converts the received digital voice signal into an analog voice signal. The analog voice signal is transmitted to the handset 101e via the emergency telephone repeater 101c, and the handset 101e outputs the voice based on the administrator's speech.

[0070] An analog call voice signal transmitted from the handset 101e in response to the user's speech is transmitted to the processing device 2 via the emergency call repeater 101c. In the processing device 2 of Fig. 3, the call voice conversion unit 17 converts the analog call voice signal into a digital call voice signal, and the second communication unit 12 transmits the digital call voice signal to the receiver 1 via the second communication line L0.

[0071] 2, when the second communication unit 12 receives a digital call voice signal, the call voice conversion unit 17 converts the received digital call voice signal into an analog call voice signal. When the fourth communication unit 14 transmits the analog call voice signal to the base unit 101d via the fourth communication line L13, the base unit 101d outputs a call voice based on the user's speech.

[0072] (1-5) Advantages of the First Embodiment (1-5-1) Receiver advantages By having the first communication unit 11 communicate with the sensor 101a via the first communication line L11 and the second communication unit 12 communicate with the processing device 2 via the second communication line L0, the receiver 1 can distribute processing related to fire alarms between the processing device 2.

[0073] Furthermore, by using a digital system for communication between the second communication unit 12 and the processing device 2, the receiver 1 can achieve one or more of the following: reducing the number of communication lines, increasing the amount of information that can be transmitted, and improving transmission quality.
