7.具有⻔开关信号反馈，⽆源信号输出。

1. It adopts 433MHz registration-free frequency band, which has good bypassing ability, and the
straight-line communication distance can reach 100 meters
2. Using standard Wiegand 26, 34 transmission protocols, it can directly connect to third-party
access control systems, thus helping traditional access control systems to realize docking with
wireless electronic locks.
3.One-to-one transmission mode, fast pairing.
4. Using AES128-bit encryption for transmission, with high security.
5. The 12V/24V power supply is compatible with most security system voltages.
6. The working current is less than 50ma, no need to increase the power capacity of the original
system.
7. With door switch state feedback, passive signal output.
