Structural Features and Working Principle

The smoke exhaust fan control system consists of low-voltage electrical components including circuit breakers, AC contactors, motor protectors, phase sequence protectors, and over/under voltage protectors. The system supports both manual and automatic operation modes.

The phase sequence and over/under voltage protectors immediately activate protection actions upon detecting over/under voltage, phase reversal, or open-circuit conditions in a three-phase AC circuit, cutting off the main circuit power supply to rapidly protect the load while triggering audible and visual fault alarms.

For manual or automatic startup, the external leads of the fire damper must be connected and the corresponding relay powered before the fan can be activated. In automatic mode, when a fire linkage signal is received, the system emits audible and visual alarms while simultaneously starting the fire fan.

The operating principle of the smoke exhaust fan control system is as follows: When the fire control center receives a fire alarm signal, the system automatically activates the fire fan and opens the exhaust valve via the fire smoke exhaust fan control cabinet, thereby exhausting the indoor dense smoke through the ductwork to the outdoors and achieving effective smoke removal.

The smoke exhaust fan control device is used to manage fire protection smoke exhaust fans. It enables the control of the fans to perform predetermined actions, receives feedback signals from the fans, monitors their operational status, communicates information with higher-level monitoring systems, and provides audible and visual alerts to relevant personnel.

The Necessity of Smoke Exhaust Fan Control Equipment

During a fire, large amounts of dense smoke are generated, which can cause poisoning or fatal asphyxiation. Installing smoke control and exhaust systems within buildings reduces the hazards posed by dense smoke to humans. Fire protection and smoke exhaust fan control equipment is primarily installed in high-rise buildings, while primary applications include underground parking lots, hotels, shopping malls, office buildings, and similar facilities.
