Next, FIG. 3 is a diagram illustrating a main part of the disaster prevention monitoring control panel 1. In FIG. 3, reference numeral 13 denotes a control circuit provided in the disaster prevention monitoring control panel 1. The control circuit 13 includes a plurality of control relays 37-1 to 37-n corresponding to the control line 10 for smoke prevention. Each is provided. The control relays 37-1 to 37-n are connected to the collectors of the transistors 38-1 to 38-n,
For example, a voltage of 24 V is always applied from the terminals 39-1 to 39-n. Diodes 40-1 to 40-n for blocking backflow are connected to the collectors of the transistors 38-1 to 38-n in parallel with the control relays 37-1 to 37-n.
The resistors 41-1 to 41-n are connected to the bases of the transistors 38-1 to 38-n, respectively.

When an operation signal from the MPU 14 is input to the bases of the transistors 38-1 to 38-n, the transistors 38-1 to 38-n are turned on, and the control relay 37-n is turned on.
1-37-n operate. Control relays 37-1 to 37-
Relay contacts 42-1 to 42-n that close when n operates are provided in the control circuit 13. Relay contact 42-1
42-n are provided corresponding to the control relays 37-1 to 37-n, and a voltage of, for example, 24 V is always applied to the relay contacts 42-1 to 42-n from the terminal 44 via the fuse 43. .

When the control relays 37-1 to 37-n are activated and the relay contacts 42-1 to 42-n are closed, a voltage of 24 V is applied to the automatic closing device 12 via the control line 10. ing. A solenoid 45 and a limit switch 46 are provided in the automatic closing device 12. 2
When a voltage of 4V is applied to the solenoid 45, the unlocking operation of the automatic closing device 12 is performed, the latch of the fire door is released, and the fire door in the open state is closed. When the latch of the fire door is released by the operation of energizing the solenoid 45, the limit switch 46 is switched from the side a to the side b.

The automatic closing device 12 and the operation confirmation circuit 19 are connected by an operation confirmation signal line 20, and the automatic closing device 12
Is activated and the limit switch 46 is switched from the a side to the b side, a current flows from the operation confirmation circuit 19 to the ground 47 of the control circuit 13 via the limit switch 46, and an operation confirmation signal is output to the MPU 14. Operation check circuit 1
9 is provided with a resistor 48 for confirming operation, and a voltage of, for example, 5 V is always applied to the resistor 48.

The A / D converter 49 converts a signal from the operation confirmation circuit 19 into a digital signal and outputs the digital signal to the signal detection unit 32. When detecting the operation confirmation signal of 5 V or less, the signal detection unit 32 operates the delay timer 50. Upon receiving the drive signal from the signal detection unit 32, the delay timer 50 operates the relay operation stop unit 33 after a predetermined delay time. After a predetermined delay time, a signal from the delay timer 50 causes the relay operation stopping unit 33 to switch the transistor 38-

Next, the operation of FIGS. 1 and 3 will be described.
It is assumed that a smoke emission detector 6 connected to a smoke emission detector line 5 drawn from the disaster prevention monitoring control panel 1 has been activated. The MPU 14 receives the fire signal from the sensor 6 via the receiving circuit 8 and, when judging that there is a fire, flashes the fire representative light 26 and the corresponding district indicator light 27 and performs EEP.
Based on the interlocking information stored in the ROM 18, the control circuit 10 for smoke prevention and smoke control which is interlocked with the sensor line 5 determined to be a fire is extracted. In this case, the control line 10 in the interlocking relationship is not limited to one line, and a plurality of lines may be registered as the interlocking information. When the MPU 14 determines that a fire has occurred, the MPU 14 flashes the fire representative light 26 and also flashes the corresponding district indicator light 27.

On the other hand, the MPU 14 controls the extracted control line 1
The transistor 38-1 is turned on so as to operate the control relay 37-1 corresponding to 0. At the same time, the MPU 14 blinks the representative smoke prevention light 25. When the transistor 38-1 is turned on, the control relay 37-1 is activated, and the relay contact 42-1 is closed. When the relay contact 42-1 closes,
24V voltage is applied to the automatic closing device 1 via the sensor line 10.
2 is applied to the solenoid 45. When the solenoid 45 operates, the unlocking operation of the automatic closing device 12 is performed, the latch of the fire door is released, and the fire door in the open state is closed. When the automatic closing device 12 is operated and the latch of the fire door is released, the limit switch 46 is switched from the side a to the side b. When the limit switch 46 is connected to the “b” side, the current is output from the operation confirmation circuit 48 to the limit switch 4.
6 to the ground 47 of the control circuit 13 and the MPU 14
, An operation confirmation signal for confirming that the automatic closing device 12 has been operated is output.

The A / D converter 49 converts the signal from the operation check circuit 19 into a digital signal and outputs the digital signal to the signal detector 32. The signal detection unit 32 monitors the digital signal and
When a signal less than V is detected, it is determined that the signal is an operation confirmation signal, and the delay timer 50 is operated. The delay timer 50 activates the relay operation stopping unit 33 after a predetermined delay time. With this activation, the relay operation stopping unit 33 causes the transistor 3 to stop the operation of the control relay 37-1.
Turn off 8-1.

When the transistor 38-1 is turned off, the operation of the control relay 37-1 is stopped and the relay contact 42-1 is turned off.
Is released. Therefore, the voltage of 24 V is not supplied to the automatic closing device 12, and the solenoid 45 is turned off. When the fire door is manually returned at the site without the disaster prevention monitoring control panel 1 being recovered, the limit switch 4
6 is switched from the b side to the a side, and the operation confirmation signal cannot be obtained. In this case, the relay operation stop unit 33 releases the stop of the operation of the control relay 37-1, and the MPU 14
Turns on the transistor 38-1 again.

As described above, the operation of the control relays 37-1 to 37-n is stopped by the relay operation stop unit 33 when the operation detection signal from the automatic closing device 12 is detected by the signal detection unit 32. When the number of control lines is large, current consumption can be reduced. As a result, the capacity of the battery can be reduced, so that the cost and the size of the device can be reduced. When the delay timer 50 is provided and the operation confirmation signal is received from the automatic closing device 12, the operation of the control relays 37-1 to 37-n is stopped after a predetermined delay time. Even if the closing device 12 outputs an operation confirmation signal before the startup is completely completed, the operation of the control relays 37-1 to 37-n is stopped after the automatic closing device 12 is securely started. Can be. Further, the timer time for setting the delay time of the delay timer 50 can be changed freely, so that it can be applied to any device.

Since the corresponding control relay is deactivated,
When the number of control lines is large, current consumption can be reduced. As a result, the battery capacity can be reduced,
Cost reduction and downsizing of the device can be achieved.
