ShanghaiSongjiang DistrictGlass automatic doors, Sensor DoorOperating process: when entering, the infrared probe detects a person and immediately signals the automatic door to open; after the pedestrian enters, the door closes automatically. When leaving, as the customer approaches the door the sensor probe detects them and signals the door (the detection range is adjustable on the probe); the door opens and closes automatically after the person leaves. If the door needs to be locked at night when no one enters or leaves, an electric bolt lock can be fitted in the automatic door track; other brands of bolt locks work but are unstable. Their electric-lock delay is door-arrival delayed locking synchronized with the single opening signal, so the door may open before the bolt has fully retracted, causing jamming; repeated jamming easily burns out the main controller. At present only the dedicated automatic door electric bolt lock can delay 2 seconds after power-off before signaling the door, and also has a 2-second delayed locking function when closing; only this achieves the new concept of unlocking first and then opening, ensuring long-term system stability.
