Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an alarm system for apartment complexes such as condominiums, and in particular, to a central alarm system installed in a manager's room etc. that transmits signals such as fire detected by an in-unit information board. Regarding the improvement of sending data to the monitoring board as well.

[Conventional examples and their problems]

A so-called in-unit information board connected to a fire detector, gas leak detector, etc. is installed in each unit of the apartment complex, and an intercom function is installed at the entrance of each unit to enable communication with the in-unit information board, and A cordless handset equipped with a test button that can perform a functional test of the fire detector, etc. of the above-mentioned dwelling unit information board from outside the dwelling unit, and further transmits the fire signal detected by the dwelling unit information board to the manager's office, etc. As for the railway line,
There is Japanese Unexamined Patent Publication No. 59-22192. In addition, with a device configured in this way, there is no need for the manager to enter each dwelling unit for testing, and the operational function of the in-house information panel, etc. can be tested using a test button installed outside the door. I can do it.

However, with conventional devices like this, it is difficult to detect a fire, etc. that has occurred within the dwelling unit during a power outage, or when the power to the information board in the dwelling unit is cut off intentionally or negligently by a resident of the dwelling unit. There was a risk of delays and serious accidents, and there were also problems such as tests using test buttons installed outside the dwelling unit could not always reliably determine if there was a break in the sensor line inside the dwelling unit.

[Failure to solve the problem]

This invention relates to an alarm system for apartment complexes that includes sensors that detect smoke, temperature, gas leaks, etc., an in-unit information panel, cordless handsets such as door phones, and a central monitoring panel installed in a manager's room, etc. , the terminal end of the line to which the sensor is connected is connected to the test switch installed on the slave unit, and when the in-house information board is cut off due to a power outage, the sensor connection line extends directly from the central monitoring board. The above-mentioned problems are solved by providing a switching circuit connected to the signal line in the in-house information panel or in the handset.

〔Example〕

Next, the present invention will be explained in detail based on the drawings showing one embodiment thereof.

FIG. 1 is a Pronk diagram showing the outline and configuration of an alarm system for apartment complexes according to the present invention, and FIGS. 2 and 3 show examples of main circuits of each part thereof.

In Figure 1, 1 is a central monitoring board installed in the manager's room of an apartment complex, and 2 is a slave unit with an intercom function installed at the door of each housing unit. Each is connected in parallel to the extended signal line. Reference numeral 3 denotes an in-house information panel, to which sensors 4 such as a fire detector and a gas leak detector are connected, and communication with the handset 2 is possible through a circuit (not shown). Note that the terminal end of the line l to which this sensor 4 is connected is connected to the slave device 2. Further, at the end of the signal line extending from the central monitoring board 1, a terminator Re for line breakage detection is provided.

FIG. 2 is a schematic circuit diagram of main parts of the cordless handset 2 and the in-house information board 3 shown in FIG. A sensor connection line l to which a stretch sensor 4.4 is connected is connected via a relay device A.

Further, a power supply line and a line extending from the normally open contact a of the relay device A are connected between the in-house information panel 3 and the handset 2.

A relay device B is connected to the slave device 2 between the positive and negative terminals of the power source, and an operation indicator light 21 is connected between the positive terminal of the power source and the terminal of the normally open contact a extending from the information panel 3. This connection point is connected to one side of the signal line extending from the central monitoring board 1 via a backflow prevention diode 22. Note that the other signal line is connected to the negative terminal of the handset 2.

The slave device 2 is further connected to the terminal end of the sensor connection line 1, which is connected to both ends of the test normally open switch SW. The normally open contact of the relay device B in the slave unit 2 is connected between the line extending from the normally open contact a and one terminal of the test switch SW, and the negative terminal of the slave unit 2 is connected to the other terminal of the test switch SW. connected to the terminal. The relay device B and its contacts constitute a circuit for switching the connection of the sensor line I to the signal line when the information board 3 is powered off.

FIG. 3 is a circuit diagram of the main parts of the central monitoring board 1, and shows the power supply 12.
In the case of a power outage, there is a backup power supply E and a switching relay, and a power supply 12.
A signal line extends through the Yoshi district relay RL.

The operation of such a circuit configuration will be described next.

When the sensor 4 is activated due to a fire, etc., the information panel 3
relay device A is activated, causing an alarm (not shown) to sound,
Notify the residents of the relevant dwelling unit. When the relay device A operates, its contact a is closed, so the indicator light 21 of the slave unit 2 lights up, and the signal line extending from the central monitoring board 1 is short-circuited via the diode 22 and the contact a. . As a result, the district relays R and L of the central monitoring board 1 are activated, an alarm (not shown) is activated, and the administrator is notified.

If the property manager performs a functional test of the in-unit information panel 3 and sensor connection line l from outside the unit, press the test switch SW.
By closing the circuit, information panel 3, slave unit 2, central monitoring panel 1
performs the same operation as that of the sensor 4 described above, and can thereby determine whether it is normal or abnormal.

When the power supply 32 of the in-house information board 3 is cut off due to a power outage, etc., the relay device B of the slave unit 2 is restored and its contacts are closed, and as a result, the sensor connection line j is connected to the signal line and contact b.
1 diode 22.

When the sensor 4 is activated in this state, since the central monitoring board 1 is equipped with a backup power source E, the district relay RL is activated, and the administrator can be notified of the abnormality in the same way as described above.

〔Effect of the invention〕

As described above, according to the alarm system for apartment complexes of the present invention, it is possible not only to disconnect the alarm equipment in the dwelling unit while the user is away and to test its function, but also to cut off the power to the information board in the dwelling unit during a power outage or intentionally by suicide or the like. This also has the effect of being able to reliably notify the manager's office of any abnormality.
