Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of the configuration of the self-fire alarm system for apartment complexes according to the present invention.
An intercom system consisting of a doorphone slave unit 11 and a doorphone slave unit 11 is installed, and disaster prevention sensors 12 such as heat detectors and smoke detectors installed in the dwelling unit are connected to the housing information panel 10 via the doorphone slave unit 11. The side of each of these dwelling units 1 and a disaster prevention receiver 2 installed in a manager's room or the like are connected by a signal line to constitute a self-fire alarm system. The alarm signal output from the door intercom slave device 11 of each dwelling unit on the same floor is transmitted to the disaster prevention receiver 2 side via the cross-connected signal lines L1, L2, etc. The output alarm transfer signal is sent to the housing information panel 10 of each dwelling unit 1 and the intercom slave unit 1 via signal lines LA1, LA2, etc.
1, and also from the disaster prevention receiver 2 to the signal line LB.
Alarm signal output via 1, LB2... (or
(alarm audio signal) is transmitted to the door intercom slave device 11 of each dwelling unit 1. Note that the signal lines LC1, LC2, . . . derived from the disaster prevention receiver 2 are laid to supply power to the disaster prevention sensors 12 of the dwelling units on the same floor.

FIG. 2 shows a detailed example of the internal configuration of the intercom slave unit 11, and the same parts as in FIG. 1 are denoted by the same reference numerals. In the figure, 110 is a door phone circuit section;
11 is an alarm switching circuit section, and 112 is a fire display circuit section. The door phone circuit unit 110 is a door phone circuit 110 that performs signal processing necessary for calling and talking with the housing information board 10.
In addition to the call switch SW1 and the speaker SP, it is equipped with an alarm test switch SW2 and a test indicator light 110b. The alarm switching circuit section 111 has interlocking relay contacts ry1 and r.
y2, and a transformer T for impedance conversion. When the alarm transfer signal is not transmitted from the disaster prevention receiver 2 side, the relay contacts ry1, ry
2 is switched to the contact a side, and the door phone circuit 110a is connected to the speaker SP. On the other hand, when the alarm transfer signal is transmitted from the disaster prevention receiver 2 side and the relay RY is driven, the relay contacts ry1 and ry2 are switched to the a side. The switch is switched to the contact b side, and the transformer T and speaker SP are connected, and an alarm sound transmitted through the transformer T via the signal line LB1 is output.

Next, the basic operation of the self-fire alarm system for apartment complexes of the present invention having such a configuration will be explained. ■When a fire occurs in one of the dwelling units 1 (temporarily assumed to be a dwelling unit on the first floor) and the disaster prevention sensor 12 issues an alarm, an alarm signal is transmitted to the fire indicator circuit section 112 of the intercom slave unit 11 and the fire indicator light is activated. 11
2a is driven to light up, an alarm transfer signal is transmitted to the housing information panel 10 via the signal line LD, and an alarm is sounded and an alarm is displayed. ■Furthermore, an alarm signal is sent from the fire display circuit section 112 of the intercom slave unit 11 to the signal line L1, and when the disaster prevention receiver 2 receives the alarm signal transmitted via the signal line L1, the disaster prevention The receiver 2 side performs the necessary alarm notification, and the housing information board of the dwelling unit that requires alarm notification (such as the dwelling unit on the same floor as the dwelling unit where the fire occurred, and the dwelling unit on the floor directly above) is transmitted via signal lines LA1 and LA2. 10 to issue an alarm notification. ■The alarm transfer signal transmitted via the signal lines LA1 and LA2 is also applied to the alarm switching circuit section 111 of the door intercom slave unit 11 to drive the relay RY, and the relay contacts ry1 and ry2 are set to the contact b side. Can be switched. Then, the transformer T is connected to the speaker SP, so the alarm sound (for example, "Woo-woo,"
"A fire has broken out," etc.) is outputted audibly from the speaker SP.

[0011] As described above, according to the self-fire alarm system for apartment complexes of the present invention, instead of providing a district bell to issue an alarm, an alarm sound is sounded from a doorbell slave installed at the entrance of each dwelling unit. It becomes possible to output and issue an alarm. Note that as the alarm sound transmitted from the disaster prevention receiver side, it is also possible to transmit a voice prompting the manager to guide evacuation.

Next, a description will be given of the operation when performing a warning test by operating the warning test switch SW2 provided on the intercom slave unit 11. - Operate the test switch (not shown) on the side of the disaster prevention receiver 2 to set the alarm transfer signal not to be sent even if the alarm signal is transmitted. ■
When the alarm test switch SW2 of the door intercom slave unit 11 is operated, both ends of the detector circuit S of the disaster prevention sensor 12 are short-circuited by the signal line LF, and an alarm signal is transmitted to the fire display circuit section 112, causing an alarm display. It is done. - From the fire display circuit section 112, an alarm transfer signal is transmitted to the housing information panel 10 side via the signal line LD to issue an alarm, and from the housing information panel 10 via the signal line LE to the door phone circuit 110a. The alarm transfer signal is transmitted to the test indicator light 110b, and the test indicator light 110b is driven to turn on. Incidentally, when the operation of the alarm test switch SW2 is released, the alarm notification on the housing information board 10 is stopped and the test indicator light 110b of the door intercom slave unit 11 is also turned off.

[0013] In this way, for each dwelling unit, by simply operating the alarm test switch of the door intercom unit installed outside the residence and confirming that the test indicator light is on, the disaster prevention sensor, housing information panel, and door intercom unit can be activated. Since it can be easily checked whether the wiring connections around the device are normal, the test can be carried out even when the resident is not present.

[0014] In the above description, the configuration is described in which the door intercom slave unit 11 is provided with a transformer T for impedance conversion, but this is not limited to such a configuration. Then, the transmitted alarm sound signal may be amplified and amplified and outputted from the speaker SP.

[0015]

[Effects of the Invention] As can be understood from the above explanation, according to the self-fire alarm system for apartment complexes of the present invention as set forth in claim 1, when a fire occurs, a doorbell installed at the entrance of each dwelling unit is activated. Since the warning sound is emitted from the device, there is no need to install district bells in the passageways on each floor of the apartment complex, making it possible to improve construction efficiency. According to the second aspect of the present invention, the wiring connection around the disaster prevention sensor can be checked by simply operating the alarm test switch of the doorbell slave device installed at the entrance and checking that the test indicator light is on. This makes it possible to easily conduct the test even when the resident is not present.
