, And (N + 1) a, (N + 1) b,..., Respectively. Incidentally, the fire occurrence signal S1 input to the security device 1 in each of the plurality of dwelling units (N-1) b,... In the same guard area B.
1 ′, the neighborhood fire occurrence signal S12 ′ is appropriately signal-processed in the security unit in the dwelling unit in the same manner as described above, and is notified as the first security zone information, so that the detailed description is omitted.

The neighborhood fire occurrence signal S12 'transmitted through the bus line L2 is, for example, one of a plurality of dwelling units Na, Nb,... Provided on the Nth floor in the same security zone A.
If it is transmitted to the security device 1 in the dwelling unit Nz provided at the terminal end of the Nth floor (to which the above-mentioned bus line connection input / output terminal T3 and bus line connection terminal T13 are connected), the above-mentioned neighborhood fire occurrence signal S12 'is input to the bus line connection input terminals T5 and T6 of the security device 1 in the dwelling unit shown in the block diagram of FIG. 2, so that the voltage level between the bus line connection input terminals T5 and T6 becomes H level.
Therefore, the photocoupler PC1 is turned on, the power supply Vcc is biased to the nearby fire detection transistor Q14 and turned on, and the voltage level of the input port P5 of the CPU 11 becomes H level. Further, when the nearby fire detection transistor Q14 is turned on, the nearby fire notification transistor Q15 is biased and turned on. Therefore,
The voltage level between the connected bus line connection input / output terminal T3 and the bus line connection terminal T13 is L level, but the zener diode Z is connected to the fire alarm detection transistor Q12.
Since the voltage drop through D1 and ZD2 becomes large and becomes equal to or less than the Zener voltage, and is turned off without being biased, the voltage level of the input port P2 of the CPU 11 becomes L level. On the other hand, since the fire alarm detection transistor Q13 is biased and turned on in the same manner as described above,
The voltage level of the input port P3 of U11 becomes H level.

Therefore, when the voltage level of the input port P2 is L
The voltage levels of the input ports P3 and P5 become H level, respectively, and the voltage levels of the output ports P6 and P11 of the CPU 11 which have detected that an emergency has occurred in a dwelling unit in the other security zone B are H level. Level.
Therefore, under the control of the CPU 11, the voice LSI 12 indicates that "a fire has occurred on the lower floor in another alert area B."
Is generated and transmitted, and the sound is sounded by the audio speaker 15 in the same manner as the above-described first warning area information S21. Further, the output port P11 of the CPU 11 is turned on / off.
Repeatedly turning off the fire indicator lamp 20 via the resistor R22
Since the power supply Vcc is biased at a constant cycle, the fire indicator light 20 blinks at a constant cycle. Therefore, an emergency situation in which a fire (neighboring fire) has occurred in any of the dwelling units in the other alert area B is notified.

In the above-described embodiment, the description has been given of an apartment house having an open corridor. However, the contents of the above-mentioned first and second guard area information are provided to the CPU constituting the security unit in the dwelling unit. A voice changeover switch that can be switched depending on the form is connected, and depending on whether the voice changeover switch is on or off, in the case of a staircase type apartment house, the warning area information is opened as an information message in block units. In the case of an apartment house having a corridor of the type, it is possible to inform the warning area information at the time of fire occurrence in an apartment house of various configurations by switching and reporting the information message as a floor unit information message.

Furthermore, in the above embodiment, the fire detector for detecting the occurrence of a fire was installed in a plurality of dwelling units provided in the apartment house. However, the present invention is not limited to this. By installing a leak detector and installing a receiving circuit that checks the operation of the gas leak detector and a detection circuit that checks the disconnection of the wiring of the fire detector and gas leak detector in the security device inside the dwelling unit, In addition to alarm notification at the time of fire occurrence, it is possible to improve disaster prevention over a wide range of situations, such as gas leak detection and disconnection confirmation.

[0034]

As is apparent from the above description, according to the security system for multiple dwelling units of the present invention, the security device in a dwelling unit installed in a plurality of dwelling units provided in the multiple dwelling unit is controlled by each security. In the area, common wiring is performed via a bus line, and signals are transmitted and received between the common-wired security devices in the dwelling unit. With the input signals, the security device in the dwelling unit determines a dwelling unit that is a fire source in a nearby fire. It is possible to specify and notify, and it is possible to improve the disaster prevention performance of the apartment house.

[Claims] After a predetermined period of time elapses or when a fire check button (23) is pressed by a security unit (1) in a dwelling unit after a dwelling unit sensor (2) of an apartment house is activated, a fire determination operation is performed to notify the occurrence of a fire. Together with the fire signal (S11, S11 ') to the living building receiver (4), and the living building receiver transmits the transmitted fire signal together with the warning area information to the neighboring fire signal (S12, S12). When transmitting to the neighboring dwelling units in the guarded area as '), the security device in the dwelling unit is commonly wired by bus lines (L1, L1') in the same guarded area, and the security device in the dwelling unit is the receiver in the dwelling unit. When the neighborhood fire occurrence signal is input to the bus line and the fire occurrence signal is output from the security device in the dwelling unit to the bus line, the first alarm area information (S21) is notified, When the neighborhood fire occurrence signal is input from the ridge receiver and the fire occurrence signal is not output from the security device in the dwelling unit to the bus line, the second warning area information (S22) is notified.
