Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a self-fire alarm device that issues a fire alarm by detecting activation of a fire detector with a receiver via a sensing line.

[Background technology] Conventionally, a fire detector is connected to a receiver via a sensing line,
a detection means for detecting activation of a fire detector in the receiver;
In a self-fire alarm system that is equipped with an alarm means that is activated when activation of any fire detector is detected, when the fire alarm means is activated, the situation at the place where the fire outbreak is detected is grasped. In order to do so, the administrator has to go to the location where the activated fire detector is installed and check it, and since the situation cannot be grasped in real time, there is a problem that prompt response to the fire alarm cannot be taken.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to be able to grasp the situation of a place where a fire outbreak is detected in real time, and to respond to a fire alarm. An object of the present invention is to provide a self-fire alarm device that allows quick response.

[Disclosure of the Invention] (Embodiment 1) Fig. 1 shows an embodiment of the present invention, in which a fire detector 1 is connected to a reception 1f33 via a sensing line 2, and the fire detector 1 is connected to the receiver 3. In a self-fire alarm system comprising a detection means 4 for detecting the activation of the fire detector 1 and an alarm means 5 activated when the activation of the fire detector 1 is detected, A telephone receiver 6 is disposed near the fire detector 1, and a communication means 7 for communicating with the above-mentioned telephone receiver 6 is provided in the reception fi3. The handset and handset 6 are integrated, and the operation of the handset and handset 7 is controlled by the normally closed liquid αr of the relay RY, which is controlled by the output contact 1& of the fire detector 1. Moreover, the handset 6 and the intercom R7 are
A telephone may be used instead, and is connected via a telephone line 8.

The operation of the embodiment will be described below. Now, under normal conditions when fire detector 1 is not operating, detection line 2
The output contact 111 of the fire detector 1 to which power is applied through is turned off, and the detection means 4 of the receiver 8!3 detects the voltage of the detector 82 and determines that no fire has occurred. At this time, since the relay RY is energized, the normally closed contact is off and the handset 6 is in a non-operating state.

Therefore, in a normal state where a fire does not occur, crosstalk does not occur through the handset 6 and the communication means 7 of the receiving fi 3, and privacy can be protected. When the fire detector 1 is activated, α1a is turned on after the output and the voltage of the sensing line 2 is
The detection means 4 of the receiver 8!3 detects this, outputs a fire detection signal, and drives the alarm means 5 to notify the occurrence of a fire. At the same time, relay RY is de-energized, normally closed contact r is turned on, and handset 6 becomes operational and ready for communication with communication means 7 of receiver 3 via the communication line. When the manager who hears the fire alarm activates the communication means 7 (picks up the handset) in order to grasp the situation of the hot water facility where the fire alarm occurred, the situation of the hot water facility where the fire alarm occurred can be easily understood by voice. It looks like this. In this case, a person at the location of the fire only needs to report the situation out loud, and even if no one is present, the situation can be grasped to some extent based on the sounds around the fire.

(Embodiment 2) FIGS. 2 and 3 show another embodiment in which an emergency push button switch 10 having two circuits of switch contacts 10a and 10b is used in place of the fire detector 1. , the operation of the handset 6 is controlled by the switch contact 10a, and the detection means 4 of the receiver 3 detects the state of the switch contact 10b to detect the occurrence of a fire or other abnormal condition, and drives the alarm means 5. It is supposed to be done. In addition, in the embodiment, the handset 6 is a beaker SP, and the amplifier circuit AMP.
As shown in FIG. 3, the telephone communication circuit is housed in a sensor body 11 that houses a relay circuit, and this sensor body 11 is inserted into a sensor socket 12 arranged on the ceiling. The push button switch 10 is installed on the wall.

[Effects of the Invention] As described above, the present invention connects a fire detector to a receiver via a sensing line, and includes a detecting means for detecting the activation of the fire detector in the receiver, and a detecting means for detecting the activation of the fire detector. In a self-fire alarm system comprising an alarm means that is finally activated when detected,
Since the fire detector has a built-in handset that becomes operational when the fire detector is activated, and the receiver is equipped with a communication means for communicating with the handset, the occurrence of a fire cannot be detected. The present invention has the advantage that the situation at the location can be grasped in real time by voice via the handset/receiver communication means, and a rapid response to a fire alarm can be taken.
