1. Anti-trailing function: The infrared light band detection area in the channel can be used to adjust the switch state according to the customer's accuracy requirements. The application of the light belt to adapt to different requirements avoids the point-to-point infrared detector being easily contaminated, which affects the reliability of judging reliability. Can effectively judge the trailing person of the unread card. When the system determines that a tail occurs, the system will respond based on the location of the active cardholder returned by the infrared detector. After the door opening signal is issued, there are still some abnormal use that will trigger the alarm system.
2. Irregular usage:
(1) When the door is closed, the reverse-entry pedestrian enters the body after the authorized door-opening signal is sent out. If the reverse sounding belt detects that someone enters before passing the first security photoelectric detection band, the buzzer will be provided as long as the person does not leave. The alarm will be issued all the time, the door will remain closed and the "ageing" function will not calculate the time interval.
(2) Reverse entry when the door is opened. After the door is opened, if an unauthorized pedestrian enters the door detection area in the reverse direction, the door is closed immediately. As long as the first protection detection belt detects the presence of someone, “aging†The function does not calculate the time at this time. When the person leaves the second detection zone, the door resumes normal work.
(3) When the pedestrian left, the reversed intruder passed the second security detection zone. Before the door returned to the basic state, the second security detection zone again detected that there was no entry, and the alarm system issued an alarm. However, as long as someone is still detected in the protection zone, the door will not close.
(4) The tail body detects the pedestrian from the first detector to the last detector that left the first security detection zone. The time gap is about 0.25 seconds. After the pedestrian leaves the first security detection zone, the reader signals. In the absence of an open door, a pedestrian (trailer) was detected in the first detection area. The alarm sounded and the door remained open.
(5) After the normal trailing pedestrian leaves the protection detection area, the first security detection area detects that an unauthorized person has entered and the door is closed immediately. The alarm sounds.
3, Drive: DC servo motor drive 4, the reaction of the door body in emergency: When the door is in operation, there will be a sudden power failure, the door wing will stop in the original position and can be pushed freely. According to the requirements, each device can be installed with an emergency button. The button activates the emergency response mode that has been selected. The channel is normally opened in the event of danger or panic. In case of emergencies such as alarms, the channel can be manually closed via the remote control button. After the power is turned on or after the emergency is released, the door will automatically reset after self-checking.

Polishing paste is the polishing material (such as diatomite, quartz sand, pumice, iron Dan, Vienna lime and chromium oxide, etc.) and some binder (such as stearic acid, paraffin, etc.) together into the form of oil paste. Polishing paste is generally divided into white, red, green three kinds, according to the material of polishing products is different, should choose different polishing paste
