Operation principle of the speed gates
When the device is connected to the power, the system will perform self-check. The device will
operate normally if no problem is detected. If a failure is detected, the system will display related
messages on the LCD display screen so that the user can have a quick knowledge of and solve
the problem.

When the reader detects a valid card/fingerprint, the display screen will show whether it is
successful or not. And the switch instruction signal is transmitted to the master control panel.
After receiving the signal from the reader and the infrared sensor, the master control panel will
send valid control signals to the servo motor driver. At this time, if the system is in forbidden
passing mode, the mode indicator light will turn red, and the master control panel will not accept
signals of card swiping/fingerprint scanning.
After the passenger passes the channel according to the opening direction of the swing arm, the
infrared sensor will keep detecting the movement of the pedestrian throughout the passage and
continue to deliver signals to the main control panel until the pedestrian passes through the
passage.
If the pedestrian enters the passage but forgets to swipe his/her card, or if the card held by the
passenger is invalid, the system will prompt an audible alarm to warn the pedestrian to stop
passing. The alarm signal will not be cancelled until the passenger retreats from the passage. A
pedestrian can pass through the lane only after successful verification with a valid card read by
the card reader.
