As shown in Figure 4, such a system installs a self-fire alarm receiver 100 in a monitoring center, fire detectors S, etc. in each room, and transmitters in passageways. P.
・When any of the fire detectors S is activated or the transmitter P is operated, the detector port 11A is installed.
An alarm signal or an emergency call signal is transmitted to the repeater 101 via s, and the repeater 101 receives this signal and sends a multiplexed signal with a unique address to the fire alarm receiver 100 via the multiplex signal line 1. The fire alarm receiver 100 identifies and displays the sensor line As connected to the sensor S that triggered the alarm and the operated transmitter P based on the address attached to the transmitted multiplex signal. , performs necessary control processing such as alarm notification.

In addition, when a fire detector goes off or a transmitter is operated, the self-fire alarm receiver side issues an alarm, and the drive signal from the self-fire alarm receiver causes an alarm installed on the transmitter side to be activated. A system has also been developed that drives audible means and alarm display means, and as shown in FIG. device line IS

Signal line I from fire alarm receiver
The alarm display means 102b and the alarm sounding means 102C provided in each transmitter 102 are driven through the signal 1 to display the alarm and sound the alarm.

However, in the above-mentioned system, when the fire detector S... is activated or when the transmitter P (102) is operated, the detector line IS is simply short-circuited, so the area where the fire has occurred cannot be detected. In order to identify it on the self-fire alarm receiver 100 side, it is necessary to provide a repeater 101 having a unique address for each divided area.
Since the wiring between the transmitter P (102) and the transmitter P (102) is troublesome and requires a lot of space for installing the repeater 101, improvements are desired.

A drive signal is output to the alarm sounding means and the alarm display means to sound the alarm and display the alarm.

In the present invention as set forth in claim 3, in place of the repeater and transmitter of the conventional fire alarm system, a transmitter having the repeater function according to claim 1 or claim 2 is used as a conventional fire alarm system. It is incorporated into a system, and its operation is the same as that of claims 1 and 2 above.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the internal configuration of the transmitter 1 of the present invention as set forth in claim 1 as a system configuration diagram in which the transmitter 1 is incorporated into a conventional fire alarm system (corresponding to claim 3). ), parts that are the same as those in the conventional system are given the same reference numerals.

In the figure, l is a transmitter having a repeater function, and is connected to the fire alarm receiver 100 via a multiplex signal line l to transmit and receive multiplexed signals, and a multiplex transmission control unit 1a, and a sensor line ns alarm detection means 1d for monitoring alarms from a plurality of sensors S connected to the transmitter; The address setting unit IC that sets the address determines whether the address attached to the multiplex signal transmitted via the multiplex transmission control unit 1a matches the address set by the address setting unit IC, and the transmitted multiplex signal is In addition to performing basic operations such as signal processing according to the signal,
When the alarm detecting means 1d receives the alarm signal from the sensor S or when the transmitting means 1e outputs an emergency call signal, the alarm is sent automatically through the multiplex transmission control section 1a with the address set in the address setting section 1c. The fire alarm receiver 100 side is configured to include a signal processing means 1b that outputs a multiplexed signal.

To explain the operation of a self-fire alarm system equipped with a transmitter 41!1 having such a configuration, during normal monitoring, a multiplex signal to which an address is attached by polling access from a self-fire alarm receiver is sent via the multiplex signal line l. This multiplexed signal is received via the multiplex transmission control section 1a of the transmitter 1, and
The signal processing circuit 11] determines whether the transmitted address matches the address set by the address setting section 1c, and if these addresses match, the signal processing circuit 1
The address set by the address setting unit 1c is attached to the current monitoring information from b and sent back as a multiplexed signal.

However, due to an emergency such as a fire, the transmission method 1e
When the transmission switch SW is operated, an emergency transmission signal is output to the signal processing circuit 1b, or when a fire occurs and the sensor S connected to the sensor line IS generates an alarm, the alarm detection means 1d detects the alarm. Then, an alarm signal is output to the signal processing circuit 1b. The signal processing circuit 1b receives these emergency transmission signals or 11-warning signals, attaches a transmitter-specific address set by the address setting section 1c, and issues a self-fire alarm with multiplexed signals via the multiplex transmission control section 1a. It is sent to the receiver side 100. Then, the fire alarm receiver 100 side receives the transmitted multiplexed signal and performs necessary control processing such as alarm notification.

In this way, by using the transmitter having the repeater function of the present invention, each transmitter 1 has a unique address, so that, for example, the sensor line derived from one transmitter 1 It is possible to easily set up a detailed monitoring area, such as not setting a configuration in which multiple fire detectors S are connected to a single monitoring area, and it is also possible to set Since there is no need for wiring between the two or for installation space for a repeater, construction is easy and space can be saved.

This transmitter 1° is the same as the transmitter 1 described in claim 1 regarding the operation during monitoring and the operation when a fire occurs, but when the transmitter switch SW is operated or the sensor S is activated. After the fire alarm receiver 100 side issues an alarm, the transmitter 1' multiplexes the multiplexed signal with the address transmitted from the fire alarm receiver 1°O side via the multiplex signal line l. The signal processing circuit 1b determines whether the address received by the transmission control unit 1a and attached to this multiplexed signal matches the address set by the address setting unit 1c, and if these addresses match, signal processing is performed. A drive signal is outputted from the circuit 1b to the alarm sounding means 1g and the alarm display means 1f to sound the alarm and display the alarm. Therefore, in such a self-fire alarm system, it is possible to immediately notify the self-fire alarm receiver 100 of the occurrence of a fire at the same time as a fire occurs, and since an alarm is also given on each transmitter 11 side, It is possible to notify promptly.
