1. A fire shutter control system comprising:
a fire detector configured to detect a fire outbreak and generate a fire signal in the event of a fire;
a fire shutter controller configured to apply a control signal to a fire shutter to enable a drive motor for operating the fire shutter to operate when the fire signal is generated by the fire detector; and
a power supply unit configured to supply power to the fire detector, the fire shutter controller, and the drive motor for operating the fire shutter,
wherein:
the fire shutter controller comprises a dual signal generation system configured to dually apply the control signal to the fire shutter to prevent failure of operation control of the fire shutter,
the power supply unit comprises a dual power supply system configured to supply emergency power to the fire detector, the fire shutter controller, and the drive motor for operating the fire shutter when main power is cut off so that the power can be supplied even in the event of a power failure,
the fire shutter controller comprises: a programmable logic controller (PLC) configured to apply a first control signal to the fire shutter when the fire signal is generated by the fire detector; a timer configured to apply a second control signal to the fire shutter after the lapse of a first time period when the fire signal is generated by the fire detector, and a relay configured to receive the first control signal from the PLC or the second control signal from the timer and transmit a close signal to the fire shutter, and
the fire shutter controller is configured as a dual signal generation system which is dually connected to the PLC and the timer and transmits dual disaster prevention signals to operate the fire shutter, by applying the first control signal to the fire shutter from the PLC through the relay to enable the drive motor and applying the second control signal to the fire shutter from the timer through the relay after the lapse of a first time period, when the fire signal is generated by the fire detector.
