に関するものである。[Detailed Description of the Invention] [Technical Field] This invention relates to a fire detection signal and transmission from a detector (installed on the ceiling of a restricted area and automatically generates a fire detection signal when a fire occurs). In response to the alarm signal from the fire alarm (installed in the corridor ring of the restricted area, which generates an alarm signal by manually pressing it when a person discovers a fire), the main acoustic device (built in the fire receiver) ) and district sound equipment (installed in each warning area, etc.), and only when a fire detection signal is input from a detector, the operation of the main sound equipment and district sound equipment is stopped by operating the sound stop switch. This relates to a fire receiver that can be used to

を作動させるようにしている。The main sound of the fire receiver and the district sound caused by the activation of the detector are likely to be activated by the detector, so the sound can be stopped by the sound stop switch at the fire receiver in consideration of the case of false alarm. However, in the case of an alarm signal from a transmitter, there is no false alarm other than human mischief, and if the alarm signal reaches a fire receiver, there is a high possibility that it is an actual fire. Therefore, when the alarm signal is input, the acoustic device is operated regardless of the state of the acoustic stop switch.

One end of a contact rf that turns on when output is connected is connected, and the other end of this contact rf is provided with a local audio equipment connection terminal BL. In addition, a district sound stop warning light LB is placed on the positive power line P.
and its current limiting resistor R, and the other end of this series circuit is connected to one switching terminal a of the district sound stop switch S, and the common terminal of this district sound stop switch S is connected to the negative power supply life. Connected to N (connected to the negative pole of the 24V DC power supply). Furthermore, a district sound device connection terminal BC is provided at the other switching terminal of the district sound stop switch S, and a contact (from the transmitter) is provided between the other switching terminal of the district sound stop switch S and the negative power line N. (turns on only in response to the alarm signal pressure) connect ra to terminal BL.
