flap barriers How it works:
1) Turn on the power, 3 seconds after the system into working condition.
2) When the card reader reads the valid card, the buzzer will make a melodious sound, prompting the pedestrians to read the card successfully. At the same time, the information read from the card is judged and processed, and an application is sent to the main control board through the flap signals
3) The main control board receives the signals from the card reader and the infrared sensor, and after comprehensive processing, sends valid control signals to the direction indicator and the motor so as to turn the direction indicator into the green arrow pass sign. At this time, if the system is in the normal Closed mode, the motor is running, the limit switch controls the motor rotation angle, the gate open (normally open mode, the motor does not move), allowing pedestrians;
4) After the pedestrians indicate through the channel barriers according to the direction indicator signs, the infrared sensor senses the whole passage of the pedestrian through the channel and continuously sends a signal to the main control board until the pedestrian has completely passed the channel;
5) Pedestrians will be forbidden to pass if the pedestrian forgets to read the card or reads the invalid card (for the normally open mode, the gate will be closed; normally closed mode, the gate will not move); and the alarm will be issued until the pedestrian exit the flap barriers Channel, before lifting the alarm; re-read the valid card side to allow traffic.
Of course, different turnstile system functions, principles are different, so see you must be based on their actual situation to choose from.
