1. Controlled by electricity, the door can be opened very quickly. 2. The inside-set controlled-circuit can efficiently avoid the man-made damage and being unlocked by the outside power-supply. 3. To unlock with the mechanical structure driven by the micro electronics machine, instead of being driven by electrical magnetic, overcomes the shortcomings and makes the lock have a longer service-life. 4. The lock can be locked up automatically or manually. Electric parameters: Input voltage: dc6v Input current: 200ma Static current:
