1) has a self-test and fault alarm functions, user-friendly maintenance and use. 2) can be connected to any control device outputs a control signal or a button or remote control, to achieve a single two-way traffic control. 3) can be arbitrarily set a single, two-way free passage. 4) automatic reset function: 120/90 degrees per rotation is automatically reset, or (multi-speed adjustable time delay within a specified time) does not pass, the system will automatically cancel the prevailing permission. 5) lighting instructions: High brightness traffic light status indicator to guide traffic. 6) Anti-trailing features: Every one who rotates 120/90 degrees, if someone followed automatically locked gates and alarm. 7) Fire input: connect with the fire alarm signal, uninterruptible power off the pole normally open. 8) Memory function: When accurate signal memory, repeatedly receive legitimate signal detected after the last one through the automatic reset, greatly improving the access speed. (This feature can dial code selection) 9) Turn the power function: When receiving a legitimate signal booster nudge rotation, soft run smoothly without impact. 10) alarm function: the illegal traffic or when the red gates, automatic alarm prompts. 11) anti-reverse function: pass the course reversal occurs, the brake lever is automatically locked and the alarm until after the reverse force disappears automatically restore access. 12) Anti-buffering function: Illegal traffic or when the red gates, automatic rear brake lever angle of rotation corresponding locking, the realization of human anti-injury. When the external force disappears automatically reset. 13) unattended: Auto power off normally open, powered automatic detection reset. 14) Quick Mute: electric power, mechanical zero wear. About 45-60 times / min scalable functions: 1, remote control and management (required instruction butt) by managing computer. 2, counting function, to achieve the number of present statistics. 3, personalized voice prompts, so that the channel closer to life.
