In this case, the same terminal device EL may be controlled from multiple operation control panels CP1 to CP3 at the same time, and the receiving unit RU is controlled by one unit, that is, by one
It cannot be configured with a frequency discrimination circuit of ~n channels. This is because signals of the same frequency may come from two or more sources, and there is a risk of interference. The terminal control panel CP4 uses three frequency discrimination circuits of 1 to n channels as shown in Figure 3, or each operation control panel CP1 to 3
It is necessary to use separate channels and use frequency discrimination circuits for 1 to 3n channels. In addition, the terminal control unit CC also has the disadvantage that the circuit configuration is complicated, such as by providing a plurality of relays corresponding to each channel.

はできない。 For example, when controlling the terminal EL of a specific fire extinguishing system from the operation control panel CP1, if the control signal at this time is 7 channels, the transmitter T1 will be sent to 7 channels by the signal from the operation unit CO during operation. Two oscillation frequency signals are output: a channel control signal and a one-channel unique signal. Amplification section
The AP converts this signal to a predetermined level and sends it out to the transmission line. The amplifier unit AU of the terminal control panel CP4 receives the signal from the operation control panel CP1, amplifies the signal attenuated by the transmission line to a predetermined level, and then connects it to the specific signal receiver RA and terminal 1 of the switching circuit SC. Output. The unique signal receiving unit RA identifies that there is a signal in one channel using the frequency discrimination circuit, and outputs this unique signal to the switching control unit CA. Switching control section
CA operates relays etc. that correspond to specific signals,
A switching circuit SC consisting of these contacts is operated. The switching circuit SC has a normally open contact rl 1-1 as shown in Figure 2.
is closed, and the two normally closed contacts rl 1-2 and rl 1-3 are opened, so only terminals 1 and 4 are connected. That is, only the signal from the operation control panel CP1 is input to the control signal receiving section RB. Control signal receiving section RB is 4
~ Due to the function of the n-channel frequency discrimination circuit,
It identifies that there is a control signal on channel 7 and outputs this control signal to the terminal control unit CB. Based on this control signal, the terminal control unit CB operates the corresponding terminal EL to control the fire extinguisher.
In this state, the operation control panel CP2 or CP
Even if you try to control from 3, the normally closed contacts rl 1-2 ,
Since rl 1-3 is open, the signal from terminal 2 or terminal 3 is not connected to terminal 4 and cannot be controlled.

同様な制御ができる。 When control from the operation control panel CP1 is not performed, control can be similarly performed from the operation control panel CP2, and at this time, priority is given to control from the operation control panel CP3. Further, when control is not performed from the operation control panels CP1 and CP2, similar control can be performed from the operation control panel CP3.
