Accordingly, the control unit 15 is a local sound stop mode setting state, even when detecting the reception of a fire signal does not output a local sound representative signals B and districts relay driving signal SB _n, district relay B _n and the audio warning device 14 Is not activated, and as a result, the district acoustic control signal E6 and the voice alarm signal E7 are not output, and therefore, the speaker 5 and the common unit speaker 6 of the dwelling unit receiver 2 do not sound. In addition, when the local acoustic control signal E6 and the audio warning signal E7 have already been output and the speaker 5 and the common use speaker 6 of the dwelling unit receiver 2 are sounding, the local acoustic stop switch 18 is turned on. it is, since the output of the local sound representative signals B and districts relay driving signal SB _n is stopped, the output of the local sound control signals E6 and audio alarm signal E7 is stopped, therefore, the speaker 5 and the dwelling unit receiver 2 The sound of the common section speaker 6 stops.
[0010]
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional fire alarm system for condominiums, a wiring test is performed between the receiver 3 for living premises and the speakers 6 for each common part without sounding the speaker 5 of the receiver 2 for dwelling units. There was a problem that it was not possible.
That is, when the wiring state between the receiver 3 for a living ridge and each of the common unit speakers 6 is determined by sounding the common unit loudspeaker 6 (between the receiver 3 for a house ridge and each common unit loudspeaker 6). Since the distance is relatively long, it is efficient as a wiring test to judge by the presence or absence of the output of an audio alarm.) If there is no wiring error or disconnection during that time and the wiring is normal, for example, the first floor is shared When the fire detector 4 of the section is activated, the shared section speakers 6 on the first and second floors sound, indicating that the wiring is normal. However, in this conventional system, the loudspeakers 5 of the receivers 2 for the dwelling units on the first and second floors also sound at the same time as the loudspeaker 6 for the common use unit emits a sound. In this case, the user is also notified of the voice alarm, and even if the user is informed in advance that the test is to be performed, there is a possibility that confusion may be caused to a certain extent. For this reason, it is not possible to perform only the wiring test between the receiver 3 for the living room and the speaker 6 for the common part without making the speaker 5 of the receiver 2 for the dwelling unit sound. The sound of the speaker 5 of the dwelling unit receiver 2 can be stopped by operating the district sound stop switch 18, but the sound of the common unit speaker 6 also stops at the same time, so that the wiring test cannot be performed by the sound alarm. .
[0011]
The present invention has been made in view of the above-described circumstances, and provides a fire alarm for an apartment house capable of performing a wiring test between a receiver for a living building and a speaker for a common part without causing the speaker of the receiver for a dwelling unit to ring. It aims to provide a system.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, the fire alarm system for an apartment house according to the first aspect of the present invention is provided at the center of a manager's room or the like of an apartment house, and emits a fire detector installed in a dwelling unit during normal monitoring. Each of the districts is provided with a control unit that outputs a district acoustic control signal to the vicinity of the fire place by receiving a fire signal output from the dwelling unit side and outputs at least a fire district signal and a district acoustic representative signal. Receiving a fire district signal and a district acoustic representative signal from a control unit of a living building receiver for monitoring a fire detector, controlling a sound of a local acoustic device such as a speaker provided in the building, and the like; In a fire alarm system for an apartment house, which is activated by generating an audio alarm signal to generate a predetermined audio alarm signal and output it to the vicinity of the fire place, the control unit of the receiver for the living building, District Acoustic Suspension When the mode is set, the output of the district acoustic control signal and the district acoustic representative signal is prohibited, and when a fire signal is received in this setting state, a fire district signal is output to the audio alarm device, and the audio alarm device is When the inspection mode setting is set, even if the district sound stop mode is set, it is activated by receiving a fire district signal from the control unit of the living building receiver and a predetermined sound alarm is issued. It is characterized in that a signal is generated and output to a common-use speaker near a fire place.
[0013]
According to this configuration, at the time of maintenance and inspection, by setting the regional acoustic stop mode for the receiver for the living building and the inspection mode for the audio alarm device, the receiver for the residential building causes the fire detector to issue a test report. When the fire signal is received, the area alarm control signal is not output, and the fire alarm signal is output to the fire alarm signal. An alarm signal is generated and output to the vicinity of the fire place. Therefore, the speaker outputs a sound alarm signal and sounds when receiving the local sound control signal. For example, in a dwelling unit receiver, the speaker does not sound, but is connected to the sound alarm signal line and sounds only with the sound alarm signal. For example, since the common unit speaker rings, a wiring test can be performed only between the living room receiver and the common unit speaker.
[0014]
The fire alarm system for an apartment house according to the second aspect of the present invention is characterized in that the audio alarm device is built in or separately provided in the receiver for the residential building.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a block diagram showing a configuration of an embodiment of a fire alarm system for an apartment house according to the present invention. In this figure, parts common to those in FIG. 6 described above are denoted by the same reference numerals, and description thereof is omitted.
The fire alarm system for a condominium according to this embodiment has a function of outputting an audio alarm signal E7 to the common unit speaker 6 at the time of maintenance and inspection even in the area acoustic stop mode setting state. That is, the audio alarm device 20 of the living room receiver 3 shown in FIG. 1 is provided with an inspection mode switch 21 for setting an inspection mode. The device 20 shifts to the inspection mode. When the inspection mode is set, the voice alarm device 20 is activated only by the fire representative signal FA and the fire district signal FAn irrespective of the input of the district acoustic representative signal B, and the fire district signal FAn is activated. Output the sound alarm signal E7 to the sound signal line KPn-KPCn on the fire floor designated by the user and the sound signal line KPn + 1-KPCn + 1 on the floor immediately above the fire floor without sounding the speaker 5 of the receiver 2 for dwelling units. The common section speaker 6 on the fire floor and the floor immediately above it is sounded.
[0017]
Further, at the time of maintenance and inspection, the district sound stop switch 18 is operated to set the district sound stop mode, and for example, when the fire detector 4 in the common area on the first floor of the apartment house 1 is fired, a voice alarm device 20 is issued. the are input and fire representative signal FA and the fire zone signal FA _1, audio warning signal E7 is output on the first floor of the audio signal line KP1-KPC1 and second floor of the audio signal line KP2-KPC2. As a result, if there is no abnormality such as wiring abnormality in the audio signal lines KP1-KPC1 and KP2-KPC2 between the living room receiver 3 and the common unit speaker 6, a sound alarm is issued from the common unit speakers 6 on the first and second floors. Is output. In this case, since the area acoustic stop mode is in effect, the area acoustic representative signal B and the area relay drive signal SBn are in an output-prohibited state, and the area acoustic control signal E6 is not output. The speaker 5 of the receiver 2 for dwelling units does not ring.
[0018]
Then, the inspector can determine the normality of the system including the wiring of the audio signal line by confirming the sound of the common section speaker 6. If the common section speaker 6 on the first floor sounds but the common section speaker 6 on the second floor does not sound, it can be determined that there is an abnormality in the audio signal lines KP2-KPC2. Conversely, if the shared speaker 6 on the second floor sounds but the shared speaker 6 on the first floor does not sound, it can be determined that there is an abnormality in the audio signal lines KP1-KPC1. Also, when the fire detector 4 gives an alarm, the speaker 11A of the living room receiver 3 also sounds, so the first floor and the second floor are shared even though the speaker 11A of the living room receiver 3 sounds. If none of the external speakers 6 sounds, it can be determined that there is a wiring abnormality in both of the audio signal lines KP1-KPC1 and KP2-KPC2.
[0019]
As shown in FIG. 2, the voice alarm device 20 includes a voice synthesizer 30, an amplifier 31, a relay circuit 32, and a CPU 33. The voice synthesizer 30 reads voice data stored in an internal memory under the control of the CPU 33, performs digital signal processing on the voice data, and outputs a voice signal. For example, the voice synthesizing unit 30 outputs a voice signal having a content such as "... a fire has occurred near here ...". The power of the amplifying unit 31 is controlled by the CPU 33 to turn on / off the power supply. During the on-time, the amplifying unit 31 amplifies the audio signal from the audio synthesizing unit 30 to a predetermined level and outputs the signal.
